Cannot recommend this one, just lost all my data that I had backed up, tried to restore after and it simply does not work anymore.

Restore functionality is very limited even when it works, it just overwrites all data, doesn't give any options to keep the current data or anything.

Also only shows the history of the previous 3 days, if you want more you have to pay.

There's a far better option: Web Habit Builder

Weird tracking behaviour for 8 minutes of a website it only recorded 3. Maybe inactivity dunno doesnt work for me

Warning: this is not actually completely free. You need to pay to see more than 3 days of detailed history. I wouldn't mind if this was clearly written in the description, but this is conveniently not mentionned anywhere, not even on the homepage!
