Summer'12 Device Program/Qt 5 Mobile Projects

We are looking for brave & experienced developers willing to port or develop apps running on top of Qt 5 before its finally release. Currently Qt 5 alpha is released, the beta version is expected during June and the final in August/September.

The main motivations for this activity are mixture of:

  • Helping testing Qt 5 itself and providing feedback while it's alpha/beta.
  • Helping testing the Qt 5 libraries for the Nokia N9.
  • Getting stories of real apps ported from Qt 4 to Qt 5. Trivial? Horrible? What are the pain points? And what about Qt Creator and the documentation available?
  • Getting developers to play with the new toys: Qt Quick 2, textures, transitions, graphics / video effects, raw OpenGL ES stuff, post-Mobility APIs, the new Qt WebKit, JSON DB, ongoing R&D on PhoneGap own JQuery based experiments...

This is the same motivation we have for the QtonPi program, but for mobile development the N9 provides a touch display and many more sensors and hardware features that bare bones boards are missing.


How to apply

Developers with a good Qt development track must apply to that thread pointing to any of these sources:

  • Your Qt 4 applications, all the better if they are ready for mobile e.g. with QML UI.
  • Your profile, Qt DevNet profile, Ohloh profile or anything showing who are you and what have you done in terms of development and community involvement.

Questions and feedback about the submissions are welcome in this forum thread.


Add yourself at the end of the queue and follow this template:

    • FirmaXML is an application to digitally sign document under BDOC standard (a profile of XAdES - XML Advanced Digital Signatures). This app is developed using QML, Qt and C++. The idea is porting FirmaXML to provide an intuitive application in order to verify digitally signed documents and sign them in mobile devices.
  2. MagicTag (Anylize song wave and tag it with the right tag), by Tong Zhang (lovewilliam) - Experienced at qt development and embedded system. Had been contributed a lot of patches to the community. Had been working on an linux distribution for a long time MagicLinux. writing patches and build the distribution. And I have experience developing hw and software on other meego based devices :) OpenWaveRadioeg. . Qt Ambassador. Some of my patches can be found here. Now I'm currently studying in Software college , Shandong University and having a good time in the Embedded system lab. I'm doing some porting job recently on an TI board(cortex-a8) to get qt5 run on it. :-) Willing to get a N9 to port my qt4-qml based apps to work with Qt5. And develop more interesting things with qt5 on n9.
    • Can you please point to your patches / contributions? Thank you.--qgil 20:50, 30 May 2012 (UTC)

We are very active in testing new Qt platforms, like necessitas, RaspberryPi, Blackberry ( We are very keen to test Qt 5 on N9 and other smartphones with our current and upcoming applications.
    • This program is for community developers working on free software projects. Is Bord open source? In any case the proposal needs to be presented by an individual developer.--qgil 21:36, 1 June 2012 (UTC)
  9. Tinger Calc, by Zeyu Pan - Tinger Calc is a powerful scientific calculator environment. It supports elementary math ( +, -, *, /, ^), trigonometric functions (sin, sinh, asin, cos, cosh, acos, tan, tanh, atan), exponential functions (exp, ln, lg, sqrt), math constants (pi, e), system functions (exit, quit, print). You can use keyboard or system input method to enter equations, and then click "Ok" to calculate results. In addition, you can use the "=" symbol to remember your temporarily value, such as "x = sin(pi/4)". Website: Nokia store: I'm a Qt Ambassador, and also participating in QtonPi program. I am very glad to port "Tinger Calc" to Nokia N9 and test Qt5 libraries.

Profiles: ohloh, gerrit, github, gitorious
  15. OpenGL ES Demos, by Ken Phillis (Kphillis) - A Series of OpenGL ES Demos aimed at introducing developers how to use OpenGL ES and QT5 features found on the N9 or N950 series of Smart Phones to create games.
    • Nice idea but what demos and how can we trust you? The link doesn't tell much about your experience on Qt and OpenGL ES.--qgil 20:00, 5 June 2012 (UTC)
    • I did not have a link ready because I am waiting for the Raspberry pi to create the OpenGL ES demos. However, in the mean time, I quickly implemented a few QT5 demos that make use of OpenGL 3+ contexts using the Core profile. These starter demos are located in this github repository, and follow a format similar to graphics tutorials that are released publicly for graphics programmers. --kphillis 00:31, 8 June 2012 (UTC)
  16. zNotes (Lightweigh crossplatform application for notes management) by Peter Savichev (proton).

  19. Wayr - Location sharing App Wayr is a location sharing application, one can send messages one at a time or repeated over a preriod of time. There are also a lite version of it with much less options Wayr-lite. I am the lone developer behind both these applications. I had much bigger plans for this application back then But mobility for symbian was not in a very great shape at that time and I didnt have a maemo device. I will love to port it to Qt5/harmattan with the features that I wanted to do in the first place. Here are my profiles gitorious,, Qt Devnet. I prefer N9.


Please add below your preference for N950 or N9 and send an email to quim.gil nokia com with your Nokia Developer userID. Make sure your Nokia Developer profile contains the right contact & shipping details. Thanks!

I have created many applications on Qt4 and submitted to different channels and would like to port them on Qt5 also.I prefer N9
  6. Qt5 on Mer timoph Qt project profile.Going to work on porting Qt4 applications and writing new ones to help test Qt5 on Mer (Qt5 will already be partly included in the next Mer release). Will start with something simple - making a bit fancier version of the Yatzy game I recently wrote using Qt4/qml and some other existing things such as Qt flying bus, same game and planning poker cards. I prefer N9
  7. DATA RECEIVED Puzzle Master, by Timur Kristóf (Venemo) - I'm mostly interested in experimenting with Qt Quick 2, including the deep C++ level. Considering that my app contains lots of custom-written QDeclarativeItem code with non-rectangular items, it would be nice to see how Qt 5 can cope with it. I'd like to port my app over to the Qt Quick 2 API, rebasing my code on top of QQuickPaintedItem and seek out other possible improvements with exciting new stuff such as QML shader effects. here is the source code and the Nokia Store link. I also wish to take a brief look at how Components would work on top of Qt 5. (Note: Because I participated in last year's device program too, I'm only applying for an N9. Don't want to deprive anyone of an N950. Note 2: I may apply at the other category too.)
  8. DATA RECEIVED VirtualVoiceNet, by Stuart Marsden (stuartmarsden) - This application provides a push to talk all informed very low bandwidth voice network. It uses multicast and encodes voice using codec2 which provides very low rate voice. It is currently a QtWidget based app but plan to port to Qt5 with a QML interface. This would be an ideal mobile app as it would allow disconnected communities to form a mesh network using B.A.T.M.A.N. and then talk. Could also be used at conferences or family gatherings to aid communication. Planning to have this true multi-platform (am waiting for a QtonPi and already runs on the desktop). I prefer N9
  9. DATA RECEIVED Frosty Window, by Nishith Mahajan (Nishith) - An Open GL project which will try to paint random crystallized water on the phone based on the users interaction.

Also, the upcoming "sensors" module ( )in VSXu can make use of the local sensors (if available) and remote sensors of another device (via. a Qt Client which sends the sensor data Wifi) to control various parameters and transitions of VSXu visuals. I am just another KDE contributor and one of the developers of VSXu. ( )I prefer N9
  14. Mash - Mobile Yammer client for N9/N950, by Saija Eteläniemi (matrixx) - The Yammer client is mostly created using QML, so it would be a point of interest for me to port it to use Qt5. In addition, I've been working on several projects for Harmattan: my stuff on github, which also uses QML and Qt components and would be fun to port. I'm Also participating in QtonPi program, a Qt Ambassador and a certified Qt Specialist. As a device preference, N9.
  15. DATA RECEIVED EmuMaster, by Marcin Kazmierczak (elemental) - It emulates popular consoles such as NES, SNES, GBA, PSX, SMD, SCD and Amiga. I am interested to port whole project to Qt5 and QtQuick 2.0, but not only. With second N9 I would be able to make multiplayer mode using NFC - I would test that functionality in Qt5 too. I prefer N9 (as mentioned).

  17. ProfileMatic, by Arto Jalkanen (ajalkane) - ProfileMatic changes device's various settings (such as used profile) based on given conditions like time of day or location. The frontend is written in QML and backend in C++. I'd like to try Qt5 on it. Lively discussion and more information about the application is at TMO's ProfileMatic support thread. I'm applying for N9, as I have N950 and N9's NFC would be useful for my NFC related testing on the application. I prefer N9
  18. TEDTalksQuick - A Qt/QML app for enjoying TEDTalks, by Dhi Aurrahman- profile page (diorahman), I'm a Qt developer (Qt Ambassador), the man behind aegislabs. I hope I could port this app to Qt5 by adding more features and better user experiences, especially in browsing the available videos, managing video archives, download manager and player. Currently the code is in this repo on github, tested on borrowed N950. Since everybody pick N9 as their preference, I prefer N950 :-)
  19. Wordsler, by Slocan - This is a word game that is written in Qt/QML, and published in the Ovi Store (Harmattan and Symbian), Maemo5 Extras, Android store and the BB Playbook store, with a single codebase. I'd also be interested in improving FeedingIt RSS Reader with QtQuick 2 features, once the python bindings are available.
  20. Stories (QML n9/n950 app. You can create Infographics and graphs about your experiences.) by Victor Bravo Bravo (victorrrbravo) - Engineer. Qt developer. Qt Ambassador. I prefer n9.
  21. Shutdown,GApp,WakeOnLan and QuickCall for Harmattan (Qt/QML), by Felipe Crochik (fcrochik@maemo, fcrochik@qt-project).

  22. Security Audit, PulseAudio Remote Audio GUI, Google Voice Integration, and VPN Tunnel Manager, by Jason A. Donenfeld (zx2c4), blog code email - The projects outlined on that page are a PulseAudio Remote Audio Interface, integration for Google Voice services, and an easy way to manage different VPN tunnels, including the awesome Iodine project that allows tunneling internet traffic through DNS relays. As for me, I'm extremely involved with Qt, attended all the FOSDEM talks, have been following very very closely the development of Qt5, write a blog on PlanetKDE, and pretty much the whole Qt-shebang. I grok pretty low in the Qt5 stack, and I'm up for not only porting, but testing internal Qt5 performance. Secondly, listed on that page is a few examples of public security experience. Face it: mobile security is important, and nobody is going to want to use a Qt5 phone if the platform is insecure. I'm interested in doing a large audit of the N950 userland and kernelland, with particular focus on aegis & webkit2, to make sure Meego users don't become easy targets. We don't want our platform to become another Android. here is a commit for a buffer overflow in Qt from a few days ago. It even has an advisory. Qt security is a real and important thing. I prefer the N950.
  23. CuteSoma ( client for N9/N950), by Andrea Grandi - Qt Profile (andreagrandi) - My intention is to port CuteSoma to Qt5 for any future devices and to release a Desktop version as well. Source code is available [3]. Qt Ambassador. I prefer N9


  1. CMake (cross compiling with Qt 5) by Stephen Kelly (steveire) - Qt maintainer, KDE developer and Qt based library developer.
    • Although an interesting project, it doesn't really fit in the original purpose of this activity. Doesn't really help showcasing Qt 5, or directly testing it before release. Thank you for your understanding.--qgil 18:02, 30 May 2012 (UTC)
  2. Some free apps on Qt-apps, by Manoj Agrawal (manoj) - Nokia Certified Qt Specialist, Qt Ambassador and QtOnPi member. Created many complex GUI applications and Qt widgets on desktop and embedded systems. Also created a App Store kind of trial application for one client who proposed it to Nokia.
    • Qt Widgets applications are in fact out of scope in this Qt 5 Mobile Projects activity. Already in Harmattan QWidget was not supported.--qgil 20:53, 30 May 2012 (UTC)
  3. Tutorials and Docs, by Johan Thelin (e8johan) - Qt5 and QML needs to be documented for it to gain a larger audience. I'm willing to do this.
    • This is an interesting area of contribution but fall out of the scope of this activity. Please reach me via email to know what do you have in mind. Thanks!--qgil 20:58, 30 May 2012 (UTC)
  4. Dynamic QImage tools for the Quru Image Server by Roland Whitehead We’ve developed an image server used for the world’s biggest single source collection of on-line dynamic images (1.6mil and growing) and we want to produce a toolkit based on QImage and QML image elements to run on multiple Qt platforms (Desktop and mobile). Currently working on desktop version. More info
    • Sorry, out of scope for this Qt 5 Mobile Projects activity.--qgil 21:01, 30 May 2012 (UTC)
  5. OBD-II based Information Center for Automobiles, by Pablo J. Rogina, QtonPi Member. Qt developer since version 3.x, I would like to integrate Qt5 + Qt Quick (dials, knobs, gauges) plus leveraging Qt Mobility (specially Bluetooth module) along with libodb to build an On Board Diagnostic application, both for the technician and the car driver. I’m a current contributor to Digital Forensics Framework (DFF), tool for digital forensics investigators written in Python and C++ using PyQt and Qt.
    • Sorry, out of scope for this Qt 5 Mobile Projects activity.--qgil 21:42, 30 May 2012 (UTC)
  6. Fire Department Management System, by Joseph Dougherty (jdougherty) - A management information system for fire departments. Joseph has worked with the Youngsville, NY fire department to develop and deploy a management system to track personnel, inventory, training, and emergencies. Joseph has been accepted into the QtOnPi device program for another project based around open source electronic voting. I would love to be able to port the FDMS to this mobile platform. The existing desktop development has been delayed due to academic responsibilities, but the project is active.
    • Previous mobile experience is appreciated for this activity. The project itself seems to be really focused for desktop.--qgil 21:39, 1 June 2012 (UTC)
  7. Updating the telepathy stack, by Rohan Garg (shadeslayer) - With my Kubuntu Developer hat on, I'd like to apply to update the entire Telepathy stack on the N9. Apparently it's pretty outdated. This also relates to Qt5 since the N9 uses telepathy-qt which will need testing against Qt 5. The latest release for telepathy qt4 is 0.9. I'm well versed with debian packaging and fixing ARM builds. The new telepathy releases also support Peer-to-Peer DBus calls, enabling developers to make P2P games.
    • Too soon for this project in the context of Qt 5? We are giving preference to projects with a tangible outcome while this one still would depend on someone else developing an app using those libraries.--qgil 21:45, 1 June 2012 (UTC)
  8. Move PDF Reader, by Naser (TheHost) - Move Reader is a new animated way of reading pdf Documents on mobile devices without the need to keep moving the view window and zooming in and out all the time.(Under Construction) + Qt Ambassador, QtonPi member, Inventor and Graduate student.
    • Project under construction. Not much info to decide.--qgil 20:01, 5 June 2012 (UTC)
  9. Infoctopus (site is under construction) - by Mikalai Arapau (kollya) - Infoctopus is a Personal Time and Resource Tracker/Manager/Analyzer mobile app (desktop app is also planned). QML and effects for UI, sqlite/JSON DB for underlying database.
    • Under construction. This activity os for Qt developers backed with existing mobile projects.--qgil 20:15, 5 June 2012 (UTC)
  10. Media center smart remote, by João Paulo Rechi Vita (jprvita), blog ohloh - I'm one of the selected developers of the QtonPi program, where my project will be a media center with web browsing abilities, using Qt5 and WebKit2. This project will become way cooler with a smart remote controller, and there is no better device to make this controller than the N950, because of its awesome built-in keyboard, touchscreen that can be used as a remote touchpad, acelerometers, plenty of conectivity options, hackable software platform, and native Qt5 suport. The Smart Remote application will talk to the media center device over Bluetooth and WiFi to control the playback, browse the media colection with content preview, display metadata about the content being played, and control the web browser. It will be the perfect showcase application of Qt5's portability and fancyness. Latter the smart remote application can be extended to control other media centers and devices, as a HTPC or a regular tablet / phone media player. I prefer the N950.
    • Project under construction.--qgil 20:15, 5 June 2012 (UTC)
  11. Snowshoe, by Rafael Brandao Lobo (rafaelbrandao) - Software engineer at INdT, I've been working most of the time with QtWebKit. Snowshoe is a Qt5-based web browser with mobile and desktop modes supported. We've been noticing some performance issues regarding scrolling on N9 which I'd like to help fixing, besides bugs on QtWebKit Qt5 API. Profiles: qtbug-reports, webkit, qtdevnet, github. I prefer N9.
    • Happy to help INdT and the Snowshoe project but let's not take more slots in this activity. Contact me if you or a colleague attends Qt Contributors Summit. Thank you for your understanding.--qgil 20:38, 5 June 2012 (UTC)
