The Ambient Temperature app for Galaxy S4 phones has just been updated with bugfixes and more sensor data.
I have received a lot of feedback, in comments, emails and Google Play, and I have listened to many of the wishes.
Donate app version
I also released a “Donate” version of the temperature app, which you may get to support the development.
It uses a different purple icon, to separate the two apps.
The free app will continue to be free.
