Clearspace puts a gate in front of the app: breathe, or do a set of pushups, before Instagram opens. It also lets a friend see when you break your own rules. Both of those are real features and Otto has neither. What Otto has is no bill and no sign-in.

The pause and the accountability partner are the product, and they work on a problem a timer does not touch: the reach for the phone you make without deciding to. If someone else seeing your slips is what would actually change your behaviour, pay for Clearspace. Otto cannot tell anyone anything, by design.
Otto is for the person who wants the app shut, not coached. No partner, no account, nothing about your usage leaving the phone, and a greyscale switch Clearspace does not have.
No paid tier, no trial that expires, no account. There is a tip jar in the settings and that is the whole business model.
