Most fitness apps treat your plan as static — you follow a spreadsheet and log reps. ApexBody flips that: its AI coach reads your recent workouts and macro patterns, then reorders and adapts your training plan so you're always progressing instead of stalling. It's a native SwiftUI iOS app built on the iOS 17 SDK.
What's in the free tier
The free tracker is genuinely useful on its own: a workout library (Upper Sculpt, Lower Power, Core Ignite), nutrition logging with calorie and protein totals, and streak plus completion tracking. You can use ApexBody free forever for logging.
Apex Pro: the adaptive AI coach
The subscription unlocks the differentiator — an AI coach with rule-based prompts (nudges, wins, plans, recovery, nutrition), an adaptive workout plan that reorders around your recent training, editable macro targets, a 7-day insights chart, and Apple Health sync. The coach isn't a generic chatbot; it's grounded in your actual logged data.
Why it's built natively
ApexBody is SwiftUI with MVVM stores, StoreKit 2 subscriptions, and UserDefaults persistence via a debounced Combine pipeline. Native means the workout UI is fast, Apple Health integration is first-class, and the subscription flow is rock-solid.
Who it's for
Lifters who've outgrown a static plan and want their app to actually respond to what they did last session — without paying for a human coach. Browse more health & wellness apps in our directory.
