Why a workout tracker without a subscription
Logging a set is a weight and a number of reps. Most of what a lifter needs from a tracker, a log, a program, charts and a timer, is simple, and it should not stop working when a trial ends or a routine limit is reached. SigmaGains keeps the whole app free so your training history is never held behind a paywall.
No account, no ads, your data
You can use the whole app as a guest. Nothing is sold, nothing is shared for advertising, and there are no ad networks in the app. If you stop using it, you can delete your account and your workout history from inside the app, or ask us to by email.
What it does not do
SigmaGains is a lifting log, not a coach. There is no AI that writes your workouts, no social feed, and no food or calorie tracking. If you want those, a different app will suit you better. If you want to log your training quickly and see it improve, this is what it is built for.
Questions
Is SigmaGains really free?
Yes. Every feature is free to use. There is no paid tier, no subscription, no free trial that runs out and no limit on workouts or routines.
Does SigmaGains show ads?
No. There are no ads, and SigmaGains does not sell your data or share it for advertising. Our privacy policy says so in writing.
Do I need an account?
No. Tap Continue as guest and start logging. Your workouts are saved to a guest account, and you can sign in with Google or Apple later to keep them across devices.
Can I delete my data?
Yes, from inside the app. Profile has a delete option for guests and signed-in users alike, and it removes your account and your workout history.
Which devices does it work on?
