Device Requirements
GapFix keeps this simple: it runs on iPhone and iPad with iOS 18.5 or later. That's the whole requirement.
The one rule
If your iPhone or iPad can update to iOS 18.5 (or iPadOS 18.5), GapFix runs on it — no model lists to squint at. You can check your current version in the iOS Settings app; if an update to 18.5 or later is available, install it and you're set.
GapFix fully supports the latest iOS releases too, including the iOS 26 Liquid Glass design.
Platform by platform
- iPhone — yes. Native app, built for one-handed daily lessons.
- iPad — yes. Native layouts designed for the bigger screen, not a scaled-up phone app.
- Android — not yet. It's in development and coming soon; your account will sync over when it arrives.
- Web browser — no. GapFix is a native mobile app; there's no web version.
- Apple Watch — no watch app. The lock-screen widgets are the closest glance-and-go option.
Connectivity
You'll need an internet connection (Wi-Fi or cellular) for most of GapFix: generating your 12-week plan, loading lessons and Boosters, and syncing progress. Your Day-1 lesson is pre-cached so it opens instantly after your plan is created, and a full offline mode is coming soon.
Accounts and multiple devices
GapFix starts anonymously — no account needed on a single device. To use GapFix on more than one device (say, iPhone and iPad), sign in with Apple, Google, LinkedIn, or email so your plan, streaks, XP, and progress sync between them.
Widgets
The home-screen Streak and Progress widgets and the lock-screen widgets ship with the app on iOS 18.5+ — no extra requirements.
Meeting the requirements but having trouble?
If your device runs iOS 18.5+ and GapFix still feels slow or unstable, the App Performance Issues article walks through the fixes — and help@gapfix.app is always open.
