Yobox: Your mini toolbox

Yobox provides a few tools: 1, A Learning Machine / Randomiser You can define a list of things to learn, the app will randomly pick tasks from the list, one at each pick; once you've mastered a task, you can mark it as 'Passed', and it will not be picked next time. The app also provides daily report and item report to track the learning history and status. A built-in list of 'Piano Skills' is included, as requested by my daughter, which she used to practise her piano skills while preparing her ABRSM piano exams. 2, QR code scanner 3, Easy file transfer between mobile devices To send file, select a file from the device, the app will generate a QR code, another device can simply scan the QR code to receive the file, no cable and no PC is needed at all. Both devices must connect to same WIFI. This feature was mainly originated from Mobox, to allow transfer data easily while upgrading phone, as Mobox was designed to be fully offline. Acknowledgements I would like to thank the authors of the icons used in Yobox as well as the developers of some open source projects. I am extremely grateful to my employer LEO TECH Services Pte Ltd for their generous support on the developing of Yobox and some colleagues for their great suggestions.
