How we compare
Prices carry a date
Every figure comes from the other app's public pricing page and is labelled with the month we checked it. Offers change; confirm before subscribing.
We name the better pick
Some of these apps do a job Otto does not. Each comparison says who should stay where they are, and why.
No affiliate links
Nothing here pays us. Links to the other apps are plain references, and a dash means we could not verify a detail, not that a feature is missing.
Try your next step in Otto
Core mail, calendar and tasks are free. AI has an allowance.
