Free to start. No ads. Ever. No subscriptions. Works offline. [Please read before downloading] Re:plan is designed to record the revision process itself. Because of this unique architecture, it does not sync with iOS Calendar, Google Calendar, or any external calendar apps. Each revision branches and saves as separate history β a data structure fundamentally different from external calendars that hold only a single version of each event. By operating entirely on-device with no server sync, Re:plan offers an ad-free, subscription-free, one-time purchase model with fully offline functionality. This is your personal space. Revise your plans as many times as you need.

Verdict
The clearest difference is in-app purchases: Manabuild at none against Re's 1. Re's advantage is ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.
