Thank you for your feedback!
Could you please be more specific about how "the graphs are slow when filtering"? Do you mean it's slow in terms of performance? If yes, could you provide specific information about the scenario and the device where the app is slow? And how it's measured?
I'm so curious just because I've put much efforts into making the app super fast in terms of performance. According to my tests and measurements (systrace, gfxinfo etc) the application runs smoothly with zero dropped frames in all scenarios even on very old devices such as Samsung Galaxy S III.
I admit my app has drawbacks and it's definitely not the best. However, I was sure it was one of the fastest submitted apps and it barely can be said to be "slow".
So, if you provide more technical details, I would greatly appreciate it! It could give me clue about what I missed maybe in terms of performance.
Thank you!
