Weight and reps are prefilled. Fine-tune them with big, simple controls.

Log. Rest. Repeat.

Complete a set and your rest timer starts automatically, unless you turn it off. Follow it on your Lock Screen or Dynamic Island.

Then review. Your next target.

YOUR EFFORT.
YOUR NEXT
TARGET.

Your targets follow what you actually lift, from your first session to your next breakthrough.

You approve every suggested change. Accept it, adjust it or keep your current target.

How targets adjust

Setting your first targets is always Free. Target suggestions are included in your first three workouts that have them, then with Pro.

  1. Your first session sets the target.

    Sets without targets take the values you actually lifted, included in Free.

    60 kg × 8 becomes your target

  2. Beat it. Approve what comes next.

    Lift more than your target and SmartGains suggests what you actually lifted. Accept it, adjust it or dismiss it.

    Previous target60 kg × 8
    You lifted62.5 kg × 8
  3. Miss it? Your target adapts with you.

    Miss it once: off days happen, and your target stays. Miss the same set twice in a row: review a lower target before your next session.

A few things worth knowing

GOOD
QUESTIONS.

The details, before your first set.

For iPhone with iOS 26.1 or later.
Apple Watch requires watchOS 26 or later.
Available in English.

Is SmartGains free?

Yes. Log workouts, build programs, use Apple Watch and keep your training history for free. Pro adds ongoing target suggestions, charts, trends and workout version history.

What does Pro include?

Ongoing target suggestions whenever your result justifies a change, progress charts and trends, the estimated 1RM chart and workout version history. Free includes target suggestions in your first three workouts that have suggestions.

What happens if Pro ends?

Nothing you created is deleted. Your workouts and history stay yours; suggestions, charts and version history return to the Free plan’s limits.

Do I need an Apple Watch?

No. SmartGains works on iPhone on its own. Apple Watch adds logging from your wrist, heart rate and active energy, and is included in Free.

Can I train without my iPhone?

Yes. Sync your workouts to Apple Watch beforehand, then complete your session without your iPhone. Results sync when you reconnect. Review target suggestions on iPhone.

Does it work offline?

You can log your sets and run rest timers offline. Your workout stays on the device and syncs when a connection is available. Account and subscription checks may need a connection.

How are new targets suggested?

SmartGains compares completed sets with their targets. When a set qualifies as an improvement, it proposes the result you actually lifted for next time. You can accept, edit or dismiss the suggestion.

Can I use my own workouts and exercises?

Yes. Create workouts and programs, add custom exercises, build supersets and adapt the session as you train. You can also start an empty workout and save it for later.

Does it work with Apple Health?

With your permission, SmartGains saves workouts to Apple Health. Apple Watch can record heart rate and active energy during your session and contribute to your Activity rings.

Can I export my training history?

Yes. Data export is included in Free. You can also edit finished workouts and delete your account from the app.
