The iOS app is buggy - no doubt about it and in no way something that can replace the web app. Considering that more and more, mobility is an issue then this is not acceptable.
On a fresh install, I log in and need two tries with the password manager for the app to accept the password.
When entering, the first thing that greets me is a blue bar covering half the buttons (screenshot below).
Everything jerks as soon as I touch it.
It needs two clicks to add a task on a different day.
It does not work offline.
Wouldn’t it be easier to simply say that you don’t have an iOS app?
