Does not support iOS 8. Telegram does.
Major issue: does not support iOS 10.
Critical issue: does not support iOS 11.
Critical issue: absence of y-values and dates animations. Not only the UX is suffering, but also it gives this contestant a HUGE advantage in performance over other participants.
Critical issue: 30 fps during 1st chart scaling on iPhone 5S. For more details read my comments about performance of entry213.
iPhone 5S, iOS 12.2
Vertical and horizontal scrolls do not cancel each other. It's not user-friendly when you select the dates with tooltip
Critical issue: filter toggle is not animated at all.
