Intervals bug

Good app overall, but the ability to include/exclude days when calculating intervals (one of the “premium” features) isn’t available, even though I paid for the upgraded version.

Very useful

I use this at least one per week when choosing dates or calculating time to appointments

Only shows 1 interval - not useful for tracking more than one due date

£4.99 wasted for the use i wanted.

It works

It works

Only helpful in wasting time

This app is a complete waste of money. It doesn’t save dates, like holiday periods, so every time I want to find out what the range is between two dates, and there’s holidays between them, I can’t manually add the holidays and save them. I tried emailing the developer but got no response.
