The demo of the app looks really fascinating!

I tried installing colar app on an Android 2.3.6 (Samsung GT-S5300) phone, but it seems it's not compatible with that device. It's a low-end phone, so I guess I will need something more powerful.

Since Google Play doesn't display the device compatibility anywhere in the store (besides "This application is not compatible with your device") could you please state the application requirements somewhere on your pages?
