Slow. Y-scales always start from zero. Part of the expected animations are missing.

— Upper bound values are cut when scaling (the attached video #1). 
— The app is slow and shows incorrect Pears value when scaling the third chart.
— Not possible to view the box with the details about points on the graphs.   
— Values on the Y-scale are cut (the attached screenshot #2).

Does not support iOS 8. Telegram does.

Major issue: Minimum value is always 0. Not only the UX is suffering, but also it gives this contestant a major advantage in performance over other participants.
Critical issue: 17 fps during bar chart scaling on iPhone 6+. For more details read my comments about performance of entry213.
