Built by a personal trainer around the question clients ask more than any other: when am I supposed to add weight? Bump is a workout tracker built around one idea: you should always know exactly when to add weight. Some lifters guess. Bump doesn't. Work from 3×8 up to 3×12 at the same weight, and when all three sets reach twelve, Bump shows that a weight increase is ready. Finish Workout saves the final result so the next session starts heavier. Lifters call it double progression. You'll call it the Bump. SMART PROGRESSION, DONE FOR YOU • Movement-aware weight jumps: +10 lb on heavy lower-body compounds, +5 lb on other compounds, +2.5 lb on isolation work • The next target is always pre-filled — walk in, lift, check it off • Ghost pre-fill shows last session's numbers right in the entry box • Optional warm-up suggestions stay separate from your three working sets PLANS THAT FIT YOUR WEEK • Two schedules: 2-day full body, or 3-day upper/lower/full body • Each comes in Foundation and Build — four movements a day, or five drawn from a different exercise pool • Read every day and every exercise before you commit, Pro plans included • Train the day you want: tap the day name to skip ahead or repeat one • Core is programmed twice a week, not bolted onto every session • Switch plans anytime — your working weights come with you • Or skip plans entirely: Custom Workouts with unlimited sets TRACK WHAT'S ACTUALLY CHANGING • Progress charts for every lift — watch the working weight climb • Optional body tracking: bodyweight, body fat %, and tape measurements • History keeps every session: duration, sets, volume, and the bumps you earned BUMP PRO — ONE PURCHASE • Build plans: five movements a day from a different exercise pool, on the same 8–12 progression rule as the free plans • Custom plan builder: assemble and name your own programs • IRON and PULSE themes, each with a matching home-screen icon • Apple Health sync for finished workouts, body weight, and body fat % • Buy it once. No subscription, ever. YOURS. ACTUALLY YOURS. • No account, no sign-in, no subscription • Everything stays on your phone — nothing is collected, ever • Export your complete training log to CSV anytime Weights in lb or kg. Works fully offline. iPhone, iOS 17 or later. Bump provides general fitness information, not medical advice. Consult a physician before starting any exercise program.
