About Lenjo: AI Fitness Coach
Lenjo is a local-first AI fitness coach that connects your workouts, recovery, nutrition, and Apple Watch signals in one continuous coaching loop. PLAN THE NEXT SESSION - Build practical strength-training plans from your goals, experience, equipment, preferences, and recent training. - Adjust the next workout from the sets, loads, reps, RPE, and recovery signals you actually record. - Keep your training history and coaching context together instead of starting over every day. TRAIN WITH IPHONE AND APPLE WATCH - Run and log workouts on iPhone for free. - With Lenjo Pro, send the plan to Lenjo Watch and track sets, reps, loads, RPE, rest, and completion from your wrist. - Lenjo Pro also adds live heart-rate recovery guidance on Watch and the post-workout heart-rate-by-set timeline when Apple Health access is granted. UNDERSTAND YOUR PROGRESS - Review weight, activity, recovery, and training trends. - Log meals manually or analyze a meal, equipment, or body-report photo you choose. - Get coaching summaries that connect training, recovery, nutrition, and your next check-in. LOCAL-FIRST AND USER-CONTROLLED - Core records are stored on your device. - Sign in with Apple and Apple Health access are optional. - Before the first AI request, Lenjo explains what will be sent to its gateway and third-party model providers. - You can decline AI processing and continue using local logging features. - Lenjo does not use your data for advertising tracking. Lenjo Pro is available as monthly and yearly auto-renewable subscriptions. Both plans unlock the same Pro benefits, including Apple Watch workout execution and recovery guidance, higher AI coach and photo-scan allowances, and deep reports. The yearly plan includes a 7-day free trial for eligible new subscribers. Payment is charged to your Apple Account after confirmation or when the trial ends. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription in the App Store or Apple Account settings. Lenjo provides fitness, training, recovery, and nutrition references only. It is not a medical device and does not provide diagnosis or treatment.
