Repp
Read full descriptionHide full description
Repp is your companion for strength training, whether you're just starting out or have been lifting for years. Track every workout for free, at the gym, in your home gym, or with no equipment at all. And when you want a clear roadmap, the AI builds you a training plan that fits your age, your level, and your equipment. TRACK WORKOUTS (FREE) Start a workout and log sets, weight, and reps with a single tap. The rest timer starts automatically. If you like, rate how hard each set felt (RPE). The weekly overview shows your workout count and total volume, and your recent sessions sit right on the Home tab. FOR EVERY LEVEL No experience needed. Before your first plan, you answer a few questions about your health: your age, injuries, and limitations go straight into the plan. Over 100 exercises come with instruction images so you can perform every movement safely. No gym? No problem. Repp also plans for your home gym or entirely with your body weight. And your plan explains everything in plain language. AI TRAINING PLAN (ONE-TIME PURCHASE) Answer a few quick questions about your goal, level, days per week, workout length, and equipment. From that, the AI builds a structured plan with training days, exercises, sets, and rep ranges. The plan runs over several weeks as a mesocycle, a training block where weight and volume increase step by step. A deload week, a deliberately lighter week for recovery, is built in. Every plan includes safety limits on weights and a medical notice. Prefer to do it yourself? Build your plan entirely by hand. And as a PDF you can take it anywhere, printed too. HOW YOUR PLAN IS BUILT Every plan follows established sports science principles: progressive overload, sensible rep ranges, and a planned deload week for recovery. What you share about your age, health, and injuries shapes the exercise selection. Safety rules also cap the starting weights, and every plan includes a medical notice. An AI plan is no substitute for medical advice. PROGRESS & STATS Volume trends, a heatmap of the muscle groups you train, your body weight history, and the progress of individual exercises. Repp detects personal records automatically, so you see every new best right away. ACHIEVEMENTS & MOTIVATION Collect badges for streaks, records, and more, as bronze, silver, and gold medals. Share your highlights with a single tap. LIVE ACTIVITY Your active workout runs on the Lock Screen and in the Dynamic Island, exercise image included. Rest timer and current set always in view, without ever opening the app. PRICING All workout tracking is free and stays free. The AI training plan is a one-time purchase, no subscription and no hidden costs. Your plan is yours to keep. YOUR DATA Your training data lives on your device and is transferred encrypted when syncing between your devices. No ad profile, no selling your data. Workouts can optionally sync with Apple Health. The answers from the health questionnaire are used only to create your plan. Repp is available in English, German, and Russian. Download Repp and turn every workout into real, visible progress.

Keln is a workout planner and tracker for people who lift. Plan your training week on a calendar, save your routines as templates, and log every set as you go. No social feed. No AI coach. No paywalls on the basics. Just a clean, focused app that respects your time at the gym. โ PLAN YOUR WEEK โ Open the calendar, drop a template onto Monday, Wednesday, Friday. Done. Your week is planned in under a minute, and every session is one tap away. โ WALK THROUGH EVERY SET โ Stop tracking, start lifting. Live mode walks you through your session set-by-set, so you stay focused on the bar โ not your phone. No scrolling, no losing your place, no "wait, what set am I on?" โ EXERCISE LIBRARY โ Never YouTube a lift again. Tap any exercise to see photos and how-to notes, right inside the app. Build templates faster, and walk into the gym already knowing every movement. โ BUILD ONCE, REUSE FOREVER โ Save your favorite routines as templates โ Push Day, Pull Day, Leg Day, your 5/3/1 cycle, whatever you run. Reuse them on any date without rebuilding from scratch. โ LOG SETS IN TWO TAPS โ Sets, reps, weight, rest timer, notes.

Pick the widgets that matter to you: โข Next workout โ your upcoming session, front and center โข Weekly activity โ what you've trained this week โข Monthly stats โ sessions logged, favorite exercise โข Total volume โ every pound you've moved โข Recent workouts โ quick access to your last five sessions โ STAY ON TRACK โ Optional notifications on your workout days so you don't lose the thread of your program. โ BUILT FOR LIFTERS โ โข Exercise history with full PR and volume tracking โข Categories for push / pull / legs / cardio / custom โข Pounds or kilograms, your call โข Rest timer per exercise โข Workout import / export โ your data is yours โข Light, dark, and system themes โข Native iOS app, fully offline โ WHO IT'S FOR โ You follow a program, or want to. You'd rather plan Sunday night than improvise Monday morning.

Keln stays out of your way. Plan your week. Track every set. Build the habit. Download Keln and schedule your first session.

Verdict
The clearest difference is in-app purchases: Keln at none against Repp's 4. Keln also leads on iOS requirement (18.0 vs 26.2). Repp's advantage is update cadence (every 3 days vs every 2 weeks). On price, ads and device support there is nothing between them.
