On the play store or arriving to your device via automatic updates soon.
Please also leave a (nice!) review on the play store - it really helps increasing exposure.
An experimental DailyChess branded version of the RHP app also exists, which will remain current with the RedHotPawn app for the foreseeable future, should you choose to use it.
It does remove Facebook and Google login though, so email & password are required to log in.
Daily Chess branded Android App
@russ saidVersion 5.0.7 will be arriving on phones today which will fix this issue for zoomed displays.
If you are experiencing oversized buttons since this update, please see this thread Thread 194561.
@nick812 saidThe Android Daily Chess branded app doesn't appear to be that interesting to people, unfortunately, which doesn't fill me with motivation for producing an iPhone version.
@Russ Are there any plans for an iPhone Daily Chess branded app?
But if I can do the same trick of auto-magically creating the Daily Chess branded version from the RHP build (using scripting), then I may try it. I am not clear on Apple's position about doing this is either. (Same app, different branding.)
