How we compare
Prices carry a date
Prices come from each app's own plan page, with the month we looked. Some we couldn't pin down, and plans change, so check before you pay.
We say when they're better
Every page says where the other app is stronger, and who'd be better off with it than with Otto.
No affiliate links
Nobody pays us to be here and the links are plain links. A dash in a table means we couldn't confirm that detail. It doesn't mean the feature is missing.
Try your next step in Otto
Core mail, calendar and tasks are free. AI has an allowance.
