Bring the program you already follow, or get one built. After your first session, every set shows what to lift next: last 175 × 8, today aim 180 × 8. One tap logs it.
Snap a notebook page, or add a coach's PDF, a Word or Excel file, screenshots or pasted text. Fortium reads it and flags the lines it isn't sure about for you to confirm.
Logging, your full history, targets, PRs, the rest timer and Strong or Hevy import are free. Fortium Pro adds the AI coach (your first 5 messages are free), more AI imports and deeper progress analysis.
IMPORT YOUR PROGRAM
- With your OK, Fortium's AI turns it into a program you review line by line. "RDL" becomes Romanian Deadlift.
- Supersets, percentages and RPE carry over as written.
- Your first AI import or AI-built plan is free.
PROGRESSIVE OVERLOAD, EXPLAINED
- Targets come from your program and last workout and go up by double progression. Tap the aim to see why: "Top of the range on every set → +5 lb."
- One tap logs a set, saved on your iPhone even with no signal. A keypad built for weights, a plate calculator and warm-up sets.
- The rest timer keeps counting when you lock your phone, and a notification says when rest is over.
RECORDS YOU CAN TRUST
- PRs show the moment you log them: estimated 1RM, weight and reps.
- Ties and warm-ups never count as PRs.
- The summary shows PRs, near misses and volume against last time. A lighter day isn't a failure.
SEE WHAT'S WORKING
- Volume, workouts, PRs and an estimated 1RM chart, free.
- A weekly streak that counts weeks that hit your target, so rest days are safe.
- A free muscle map of your hard sets. Pro adds muscle balance against your goal, 8-week muscle trends and a Strength Score.
A COACH THAT READS YOUR LOG (PRO)
- Ask why a lift stalled or what to swap when an exercise doesn't suit you. The coach answers from your own sets and shows which ones it used.
- It suggests changes as a before and after. Nothing changes until you approve.
- It doesn't diagnose pain or injury. For that, see a doctor or physical therapist.

PRIVACY
No ads and no tracking. Nothing goes to Anthropic, the company that makes Claude, until you say yes. It processes what you import, your plan answers and coach chats, with a summary of your training and bodyweight, never your name or email. It doesn't train on it and deletes it within 30 days unless it's flagged for a safety review. No sign-up: your training log backs up on its own to servers in the EU.
A gym log and workout tracker for strength training and weightlifting. There's no Apple Watch app yet.
