Pull-Up Trainer takes you from wherever you are today โ€” even zero unassisted reps โ€” to 20 strict pull-ups, using the proven Armstrong Pull-Up Program with the rough edges fixed. Most pull-up apps just count. This one coaches. THE PROGRAM, DONE PROPERLY โ€ข A real 5-day week: max-effort day, pyramid day, grip-switch training sets, max day, and a "repeat your hardest day" finisher โ€” the actual Armstrong structure, not a watered-down copy. โ€ข Pyramid rest scaling that adjusts to the set you just finished, so you recover exactly as much as the program intends. โ€ข Training-set calibration: the app learns your repeatable, sub-failure number and adjusts it up when it's easy and down when you stall. START FROM ZERO โ€” WITH A BAND Can't do a pull-up yet? Start with a resistance band and do real pull-ups from day one. Pull-Up Trainer walks you down a clear path of less and less help โ€” both feet in the band, one foot, one knee, a lighter band, negatives, and finally your first unassisted rep โ€” based on your reps and sets, not band colour (which no two brands agree on anyway). The moment you get that first bare-bar rep, it hands you onto the full program. You watch your strength climb as the help comes off. A REST TIMER THAT REACHES YOU The rest timer keeps counting when you leave the app or lock your phone, and sends a Time-Sensitive alert the moment your break is over โ€” so it cuts through Focus and Do Not Disturb, and you never sit around guessing. Choose silent, sound, or haptic cues so you can train anywhere. A SAFETY NET THE ORIGINAL NEVER HAD โ€ข Overtraining guard: detects stalls and regressions and recommends a deload before you dig a hole. โ€ข One-tap injury/illness reset: rebuild back to full volume on a sane ramp instead of guessing. HONEST PRICING Free for 21 days โ€” the whole app, no crippling. Finish the 21-Day Challenge and lock in a discounted one-time unlock; otherwise a simple one-time unlock. Pay once, own it forever. No ads. No subscription. Ever. Your training history stays viewable even if you never buy. Built by a lifter who wanted the pull-up app that didn't exist. Clean, fast, and focused on one thing: getting you to 20.
