Thingspeak 8000 limit workaround

I have a few Thingspeak channels that stores temperatures and various data and sometimes I like to se historical data. Then this 8000 rows limit makes it hard and takes long time to view.
I decided to make an app that make a workaround to this problem. The app seemlessly adds 8000 rows chunks to your data until the desired timespan is filled. Then next time you start the app only small updates is needed.
I also made the drawing in OpenGL so its smooth even if you have many datapoints.
However I want to make it public but at the moment I have it in beta on PlayStore and it would be appreciated if somebody wanted to test it.

Thank you!
