Average to poor performance, no data points info on tap, parts of the expected animations are missing.

Many design issues - insets for view with chart, insets for range selection, spacings between buttons.

Column visibility changes are not animated. Biggest visible y-axis label is 85%, but it should be 100%.

I was unable to select a date on any chart by tapping on the chart area.

Thanks for the feedback. Physically did not have time: (

Taking this opportunity, I want to thank the Telegram team for organizing this event, and all the guys for the feedback!
I first participated in this kind of event. In general, there was not even a certainty that there would be at least some result.
I did not participate in the first stage, and the second stage began with a delay of 1 day. Just -7 days of life, work in the mode of 20 hours a day, euphoria, adrenaline, the spirit of competition. I did everything I could, but participation was worth it!
Special thanks for the fact that the app still got to the contest, since I mistakenly sent an IPA signed for the AppStore - this was at the last minute of the deadline, since the public link in TestFlight was still not available.

— The app is laggy and blinks when filtering.
— The app supports iOS 12+ only.
