plus one

Now in beta on TestFlight

Beat last time. Every time.

The workout tracker built on progressive overload. Every set gets a target: one more rep, or the next weight once you've earned it.

How it works

One more than last time.

Progressive overload is the one rule every strength program agrees on: to keep getting stronger, do a little more over time. Plus One turns that into a single number to beat on every set.

Bench Press Range: 8 to 10 reps
135lb×8

  1. Log your sets.

    Weight and reps, set by set. Plus One remembers every one, so it always knows what you did last time.

  2. Beat it by one.

    Each set gets a target: one more rep, until you reach the top of your range. Then the weight goes up and the reps start over.

  3. Stuck? Change one thing.

    Two flat sessions in a row and Plus One suggests one change: add a set, slow the lowering, or rest longer. If nothing moves, it plans a lighter day and builds you back up.

Features

Built for the next rep.

Everything in Plus One points at one thing: doing a little more than last time, and knowing when not to.

Targets

Know exactly what to beat.

Start a workout and every set already has a number on it, based on last time. No mental math, no scrolling back through old logs.

  • Reps first, then weight. Climb a rep at a time until you top out the range, then move up.
  • Jumps sized to your gear. Plates, dumbbells, machines and kettlebells each step up by the amount they really can, in lb or kg.
  • Tell it how it felt. Tap Easy, Solid or All out. Easy days earn a bigger step next time.

Every finish

See what moved.

Finish a workout and Plus One shows how many sets beat last time, which lifts moved up, your new personal records, and the next target for every lift.

  • Fair comparisons. Sets are compared by estimated strength, so 140 × 8 and 135 × 10 are measured on the same scale.
  • Records that mean something. Change your grip or depth? Mark it as a new variation and it starts a fresh comparison.

Programs

A program built for you, with a score to prove it.

Answer a few questions about your goal, experience, days per week and equipment. Plus One builds a program from evidence-based templates, from a one-day Big Six to Push / Pull / Legs.

  • Program Score from 0 to 100. Rated on weekly sets per muscle, how often each muscle is trained, and session length.
  • Live as you edit. Change a routine and watch the score move, with suggestions for the biggest wins.
  • Flexible schedule. Train any days you like, or pick set weekdays. 1 to 6 days a week.

Progress

Watch your strength climb.

A strength chart for every lift, with a plain-English explanation of what's changed. See your real gains since you started, not just your heaviest day.

  • Muscle heat map. See which muscles you trained this week, month or quarter, on a 3D body.
  • History in chapters. Workouts grouped by program, with a training calendar and streaks.

Recovery

Push on good days. Hold on bad ones.

Connect Apple Health and Plus One turns your sleep, overnight HRV and resting heart rate into a daily recovery score, measured against your own normal.

  • Sleep-aware targets. When recovery is low, Plus One holds your weights instead of pushing them up.
  • Early warnings. A raised breathing rate or wrist temperature overnight can flag an off day before you feel it.
  • Saves to Apple Health. Workouts, how hard they felt, and weigh-ins you log.

Apple Watch

Log from your wrist.

Start a routine on Apple Watch, log sets with the Digital Crown, and see your heart rate and calories live. Your iPhone follows along.

  • Rest timer everywhere. On your wrist, on the Lock Screen and in the Dynamic Island, with +15s and Skip.
  • Heart-rate zones. See your zones, your peak, and how fast your heart rate drops between sets.
  • Closes your rings. Watch workouts count toward Activity.
