Lazee is a strength training tracker built for weight lifters who want a simple, fast way to log workouts. BUILD YOUR ROUTINE Create workout days like Push, Pull, Legs, Upper, Lower, or whatever split fits your training. Add exercises from the built-in library or roll your own. Set target sets, rep ranges, and starting weights once. LOG FAST, LIFT MORE Logging a set takes two taps in the common case. Suggested weights appear based on your past sessions. The rest timer fires automatically between sets with subtle haptics and an optional chime. Swap exercises mid-workout if the machine is taken. Pause when life happens, resume when you're back. SEE YOUR PROGRESS Every session is saved with full history — sets, reps, weights, dates. Dive into any exercise to see how your top set has moved over weeks and months. Watch the line go up. APPLE HEALTH Every finished workout is written to Apple Health as a Traditional Strength Training session, so your lifts show up in the Fitness app and count toward your activity rings. The integration is optional, toggle it on or off any time in Settings › Apple Health. Lazee writes only the workout start and end time, and never reads any data back from Apple Health. PRIVACY FIRST, NO EXCEPTIONS Lazee has no servers. No analytics. No third-party SDKs. No advertising. Your workout data lives only on your device and in your private iCloud — synced across your iPhones automatically. The developer has zero access to your data, ever. BUILT FOR iPHONE, MADE FOR iOS Native SwiftUI. Dark mode. Dynamic Type. VoiceOver-friendly. Apple Health integration — Lazee writes your sessions to the Fitness app so they show up alongside your other workouts. FREE TO USE No subscription. No paywall. No ads. No tracking. OTHER NICETIES • Export every set you've ever logged as a CSV • Share a workout-day template with a friend via a simple link • Reorder your workout days to match the order you actually train them • Optional water reminders during workouts • Built-in exercise library covering the major lifts • Switch between lbs and kg without losing history Whether you run Upper/Lower, PPL, Arnold split, or your own program, Lazee gets out of the way so you can focus on the lift.
