Reporting a bug? Tell us your iPhone model, iOS version and Fortium version (Profile › About), what you did and what happened. Screenshots help.

Getting started

Do I need an account?

No. Fortium starts right away with an anonymous account, with no sign-up, and your training backs up on its own to servers in the EU whenever you're online.

What does Fortium cost?

Fortium is free to download and use. Logging, your full history, targets, records, the rest timer, calculators, a program of any length, unlimited routines and CSV import are free. Fortium Pro adds the AI coach, more AI imports and AI-built plans, a weekly check-in and deeper analysis. It costs $59.99 a year (with a 7-day free trial) or $11.99 a month in the US; your local price is shown in the App Store.

Which devices does Fortium support?

iPhone with iOS 18 or later. There is no Android version, and no Apple Watch app yet (a simple Watch logger is planned after launch).

Importing

What can I import?

A photo of a handwritten page, a PDF, a Word or Excel file, screenshots or pasted text, in English. Fortium can't read Google Sheets links or videos yet. Your first AI import (or AI-built plan) is free; Fortium Pro includes up to 20 imports in any 30 days.

How does import work?

Choose Import, then pick a photo, file or text. Fortium reads it, matches each line to an exercise and flags every line it isn't sure about, showing what you wrote next to what it matched. Anything it couldn't use is listed. Check the flagged lines, then save. Nothing is saved until you confirm.

Fortium misread a line. What do I do?

Tap the line on the review screen and pick the right exercise, sets or reps. After saving, you can still edit any exercise in the Program tab.

Switching from Strong or Hevy

  1. In Strong or Hevy, use the app's data export option to save your workouts as a CSV file.
  2. In Fortium, open Program › + › Import a program, tap Strong export (CSV) or Hevy export (CSV) and choose the file.
  3. Fortium imports your workouts, records and "last time" numbers, so your targets are right from the first session.

CSV import is free and runs on your iPhone; no AI is involved.

Subscriptions

What does Fortium Pro add?

The AI coach, which reads your log and proposes changes you approve (up to 150 messages in any 30 days); up to 20 AI imports and 15 AI-built plans in any 30 days; a weekly AI check-in; and muscle balance against your weekly target, 8-week muscle trends and your Strength Score.

How do I cancel?

Open iPhone Settings › your name › Subscriptions › Fortium › Cancel Subscription. Cancel at least 24 hours before the renewal date or the end of your free trial to avoid being charged. You keep Pro until the end of the period you paid for.

How do I get a refund?

Apple handles all payments and refunds. Request a refund at reportaproblem.apple.com.

I bought Pro but it isn't unlocked

Tap Restore on the Fortium Pro screen, or Restore purchases in Profile › Fortium Pro, signed in with the same Apple ID you used to buy it. Still stuck? Email us.

Your data

How do I move to a new phone?

Fortium has no sign-in yet, so your backup can only be reached from the iPhone that made it. Before you switch, export your data (Profile › Privacy & data › Export my data) to keep a copy of your own.

How do I export my data?

Profile (top right of Today) › Privacy & data › Export my data gives you every set you've logged as a CSV file you can keep or open in a spreadsheet, plus your programs, routines, exercises, body weight and coach chat.

How do I delete my account?

Profile (top right of Today) › Privacy & data › Delete all data on this device erases everything on your iPhone and deletes your account and its backup on our server, at once or as soon as you're back online. This can't be undone. If you have a subscription, cancel it in your iPhone Settings too, because Apple handles billing. You can also email us to ask for deletion.

AI and privacy

How do I turn AI off?

Profile (top right of Today) › Privacy & data › AI features, then Turn off. Logging, history, targets and records keep working.

What is sent to the AI?

Only what a feature needs: the files you import, your messages to the coach, your onboarding answers, a summary of your training, and injuries or limits you told Fortium about when they matter. Never your name, email or Apple Health data. See How Fortium uses AI.

Apple Health

Apple Health integration is planned for a future version. When it's available, you can change what Fortium can read or write in iPhone Settings › Privacy & Security › Health › Fortium.
