Tired of fiddly logging? With LuniFIT, you just chat, and the AI takes care of the rest. "Toast and eggs for breakfast" "Weight 65 kg" "Two glasses of water and a 30-minute run" Type it like you'd say it, snap a photo, or just speak. Luni sorts out the calories, nutrition, and records, then gently coaches your next step. What Luni helps with • Meals: name what you ate, or take a photo, and calories and nutrition are logged automatically • Workouts: say the exercise and amount, and calories burned are calculated • Fasting: a live intermittent fasting timer with routine reminders • Weight: trends and progress toward your goal • Water: track your daily intake, glass by glass • Cycle: log your period and see predicted dates and phases Three ways to log • Naturally by chat: type, dictate, or send a photo, even several things in one sentence • The + button: quick entry from a bottom sheet • Stats tab: review and add directly Luni remembers, and reaches out first Luni is a companion, not a nag. It remembers your goals, your habits, and what you told it, and keeps the thread going: "You slept better than last week." When it matters, Luni writes first with a reminder, a nudge, or a little care. Promises you actually keep Set small daily promises with an alarm. Mission alarms ask you to complete your selected mission before dismissing the alarm, helping everyday habits stick. See your progress • Daily, weekly, and monthly stats for meals, workouts, fasting, weight, and water • Reports written like a letter: how your day went, and one thing to try tomorrow • Connect your health app to bring sleep and steps into the picture Available in English, Spanish, Korean, and Japanese.

About

RekAi

RekAi builds you a workout, then coaches you through it. Tell it what equipment you have, how long you've got and what hurts today. It writes a session around that — the right movements in the right order, with the weight and reps already worked out for your bodyweight and experience. BUILT FOR YOU, NOT PICKED FROM A LIST Every session is written for the equipment in front of you, the time on your clock and the state of your body that day. Tweaked your shoulder? It programmes around it and keeps programming around it until you say otherwise. You are unique and RekAi makes sure that to keep it that way IT REMEMBERS YOU Finish a session and the next one starts where you left off. Loads climb when you handle them and hold when you don't. Muscles you trained hard get left alone to recover. Nothing repeats inside a week. A REAL PROGRAM, NOT JUST TODAY Train towards something — get stronger, lean out, a date in the diary — and RekAi lays out the weeks to get there, then writes each session in its place. WHILE YOU TRAIN A clear timer you can read from the floor. Audio cues so you can put the phone down. Demonstrations of every movement. Swap any exercise mid-session when the rack is taken. Log what you actually did, not what you were told to do. WHAT IT WON'T DO It won't invent numbers. Weights come from arithmetic on what you've lifted, and the session totals are the real totals. FREE TO TRY Three sessions without an account, seven once you've made one. After that, a monthly subscription keeps your coach, your program and everything you've logged. Subscriptions: RekAi offers monthly and yearly auto-renewable subscriptions. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings.
