Most workout apps hand you a template. Sessionz builds your week from your actual data โ€” and explains every choice it makes. AN AI COACH THAT KNOWS YOUR NUMBERS Every set you log feeds your next plan. Press 20 kg for 8 this week, and next week's plan targets 20 kg for 10 โ€” or steps you up to the next dumbbell you own. Real progressive overload, computed from your history. IT LISTENS TO YOUR BODY With your permission, Sessionz reads your Apple Health summary โ€” resting heart rate, HRV, sleep, recent training. Slept badly? Volume comes down and rests get longer. Coming off a break? Your week ramps up instead of burying you. YOUR EQUIPMENT, RESPECTED โ€” ABSOLUTELY Tell Sessionz exactly what you own. Two dumbbells and a floor? You'll never see a bench press, a machine, or "elevate your feet on a box." Suggested weights are only ever plates you actually have. EVERY PLAN EXPLAINS ITSELF Each plan opens with a coach's note citing your numbers: "Your floor press is at 20 kg, so week one pushes for 10 reps before moving up." No black box. No generic filler. MAKE THE PLAN YOURS Swap any exercise or add a new one โ€” type it yourself, or let the AI suggest an alternative that fits your equipment and the muscles you've already trained that day. Adjust sets, reps, and rest in a tap. YOUR LAST WORKOUT WRITES YOUR NEXT ONE Finish your week and tap Generate Next Week. You get the sequel, not a reroll: the same program structure, mostly the same exercises, and every target advanced from what you actually lifted โ€” with a note on exactly what changed and why. TRAIN WITH A GUIDED SESSION PLAYER Weights, reps, rest timers, and progress on one screen. Log sets from your iPhone or Apple Watch, see what's next during every rest, and finish with a summary that calls out your PRs. SEE YOURSELF GET STRONGER Your History tab is a performance hub. A Personal Records wall shows your best lift on every exercise. Tap any exercise for a progression chart โ€” best weight or estimated 1RM over time, with gold markers on every record. Sessions where you set a PR wear a gold badge. The data is the reward. TRAIN ANYWHERE โ€” ONLINE OR NOT The whole app works offline: browse plans, run sessions, log every set, and review your history with no connection. Only generating new AI plans and suggestions needs the internet, and Sessionz tells you clearly when those are paused. BUILT INTO YOUR APPLE ECOSYSTEM โ€ข Apple Watch companion: log sets and run rest timers from your wrist โ€ข Workouts save to Apple Fitness and credit your rings โ€ข Health data is read at plan time and your training history stays on your device TRACK WHAT MATTERS Day streaks, weekly session counts, top weights, and personal records โ€” celebrated properly. Every plan is a complete 7-day week โ€” training days and rest days both programmed, and validated before it ever reaches you. Sessionz.ai is powered by Claude, Anthropic's AI. An active subscription includes a monthly pool of AI credits โ€” spend them on fresh 7-day plans or smart exercise swaps, and check your balance any time in Settings. Download Sessionz, tell it what you own and what you're chasing, and get a week of training that was written for exactly one person: you.

Body Charge

Read full description

Body Charge turns your Apple Watch data into one simple number: how much energy you have, from 0 to 100. Like a battery, you recharge overnight with sleep and drain through the day with activity and stress. One glance tells you whether today is a day to push hard or take it easy. HOW IT WORKS Body Charge reads your sleep, heart rate, heart rate variability (HRV), breathing, wrist temperature and activity from Apple Health, and learns YOUR personal normal over time. Everything is compared to your own baseline โ€” not generic averages โ€” so the number actually fits you. WHAT YOU SEE โ€ข A live energy level, shown as a real battery that fills and drains โ€ข Your morning charge and how the day has spent it, hour by hour โ€ข A forecast of where your energy is heading before bedtime โ€ข What drained you most today โ€” and what helped you recover โ€ข Sleep, HRV, resting heart rate and activity, each compared to your norm โ€ข A plain-language breakdown of exactly why your number is what it is TRENDS See your morning charge across weeks and months, track sleep debt as it builds, and keep your training load in a healthy range. ON YOUR WRIST A Watch app and complications put your charge right on your watch face. HONEST BY DESIGN When there isn't enough data, Body Charge tells you the number is an estimate instead of pretending to be precise. DATA AND PRIVACY Body Charge calculates your energy on your device. Raw Apple Health samples are not sent as analytics events. Firebase Analytics and Crashlytics collect app usage, derived energy scores, self-reported energy ratings, purchase events, device information and crash reports to improve the app. We do not use these data for advertising tracking. Optional Body Charge AI sends a limited derived summary when you ask a question, after separate consent. Body Charge is free to download. Optional Body Charge Pro subscriptions unlock additional features. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Body Charge is a wellness app, not a medical device. It does not diagnose, treat, or prevent any condition.
