OmniFocus 4 is a GTD® app for Apple devices: projects, tags, custom perspectives, a Forecast view with calendar events and a built-in review mode, on Mac, iPhone, iPad, Apple Watch and Apple Vision Pro, with web access as an add-on. Its site lists one-time licences at $74.99 (Standard) and $149.99 (Pro), or a subscription at $99.99 a year including the web, with a 14-day trial. The Over Achiever runs the full GTD flow, the horizons of focus and guided weekly and monthly reviews on iPhone, iPad and any browser, so Windows and Mac users get the complete app, at $4.99 a month or $39.99 a year, with a free trial. An Android app is coming to Google Play.
A note on method: we make The Over Achiever. The table is built from what each vendor publishes on its own site, features, platforms and prices as of September 2026, not from our opinion of the other app. Check both sites for current prices.
