Frequently Asked Questions

Got questions? We have answers.

Is Featherweight free?

Free for early adopters with no ads. We plan to introduce a small monthly subscription in the future to sustain development costs, but early users will always get the best deal.

How does AI programme import work?

Paste any text describing a training programme - from a coach email, Reddit post, PDF, or spreadsheet. AI parses it into structured workouts with exercises, sets, reps, weights, and percentages.

What makes voice input different?

Tap the microphone, speak naturally ("bench press 3 sets of 8 at 185 pounds RPE 7"), and AI transcribes, parses the structure, and matches to exercises. Hands-free logging during rest periods.

What does "% of 1RM" mean?

Every set displays your current weight as a percentage of your estimated 1RM, calculated in real-time as you log. "225 lbs (81% of 1RM)" - immediate context for intensity.

How is 1RM calculated?

Exercise-specific formulas: Brzycki for compounds, adjusted calculations for weighted bodyweight movements (pull-ups/dips), and 10% reduction for isolations where smaller muscles fatigue faster.

What is deviation tracking?

When you swap exercises, skip sets, or modify weights from your programme, the app tracks it. See: exercises swapped, exercises skipped, volume deviation %, intensity deviation %. Know if you actually followed your plan.

Can I export my data?

Yes. Export all workout data in OpenWeight format - an open standard for strength training data. Your data is portable. No vendor lock-in.

Does it work offline?

Yes. Featherweight is offline-first. All workouts stored locally on device. Cloud sync is optional and works when you have internet.

What exercises are included?

300+ exercises with muscle groups and equipment tags. Create unlimited custom exercises. Teach the app your shortcuts ("DB bench" → "Dumbbell Bench Press") via aliases.

Is it available on iOS?

Android first. iOS planned based on demand.
