Boost vs Keln

Boost is the minimal workout log for people who just want to lift and go. No bloated exercise libraries. No setup wizards. No account required. Just a clean, beautiful way to log your sets, reps, and PRs — and get on with your day. What you can do: • Log workouts in seconds • Save and reuse your favorite templates • Track sets, reps, and weight • See your personal records at a glance • Keep your full workout history Built for everyone: Whether you're brand new to the gym or you've been lifting for years, Boost gets out of your way. Beginners love that there's nothing to figure out. Experienced lifters love that there's nothing in the way. No accounts. No ads. No noise. Just your workouts. Boost. Lift. Log. Done.

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. — PLAN YOUR WEEK — 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. — WALK THROUGH EVERY SET — Stop tracking, start lifting. Live mode walks you through your session set-by-set, so you stay focused on the bar — not your phone. No scrolling, no losing your place, no "wait, what set am I on?" — EXERCISE LIBRARY — 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. — BUILD ONCE, REUSE FOREVER — Save your favorite routines as templates — Push Day, Pull Day, Leg Day, your 5/3/1 cycle, whatever you run. Reuse them on any date without rebuilding from scratch. — LOG SETS IN TWO TAPS — Sets, reps, weight, rest timer, notes. The logging screen is built for one-handed use between sets, not for scrolling a feed. — SEE REAL PROGRESS — A home dashboard you actually customize. Pick the widgets that matter to you: • Next workout — your upcoming session, front and center • Weekly activity — what you've trained this week • Monthly stats — sessions logged, favorite exercise • Total volume — every pound you've moved • Recent workouts — quick access to your last five sessions — STAY ON TRACK — Optional notifications on your workout days so you don't lose the thread of your program. — BUILT FOR LIFTERS — • Exercise history with full PR and volume tracking • Categories for push / pull / legs / cardio / custom • Pounds or kilograms, your call • Rest timer per exercise • Workout import / export — your data is yours • Light, dark, and system themes • Native iOS app, fully offline — WHO IT'S FOR — You follow a program, or want to. You'd rather plan Sunday night than improvise Monday morning. You don't need a community, you need a calendar that knows what "Push Day" means. — WHO IT'S NOT FOR — If you want food tracking, group challenges, or a chatbot telling you to hydrate, there are other apps for that. Keln stays out of your way. Plan your week. Track every set. Build the habit. Download Keln and schedule your first session.
