It works in a basement.
Every set saves to your phone first and sends when you have signal again. You never wait on a network to log a lift.
Heart rate from the watch you already wear.
Mason reads heart rate and body weight from Apple Health or Health Connect, and saves finished workouts back. Any watch or app that saves there works.
Your watch can count the reps.
With Mason on an Apple Watch or Wear OS watch, your watch counts each set and fills in the reps for the workout running on your phone. You confirm before anything is saved.
Your history comes with you.
Export your workouts from Lyfta, Hevy or Strong and choose the file in Mason. It works out what each exercise is and shows you everything before anything is added.
You can see what changed.
Volume, workouts and time trained, week by week or month by month, a muscle figure showing what your training worked, and the personal records you set along the way.
You don't need a coach.
Build your own routine and log it, with a rest timer between sets and a food diary for calories and macros. Add a coach later if you want a programme written for you.
You choose what each coach sees.
Nothing is shared until you say so, separately for each coach. Switch it off in the app whenever you like.
Mason operates under Malaysia's Personal Data Protection Act 2010. You can request a copy or deletion of your data.

Questions we get asked
Still unsure? Email hello@masonfitness.app and a human will reply.
Which wearables does Mason support?
Two kinds of support. For heart rate and body weight, Mason reads Apple Health on iPhone and Health Connect on Android, and saves your finished workouts back there, so any watch or app that saves to Apple Health or Health Connect works with Mason. For counting reps, Mason has its own app for Apple Watch and Wear OS watches: it counts each set during a workout running on your phone, and you confirm the reps before they are saved.
Do I need a coach to use the app?
No. Mason works fully on its own: build your routine, log your sets, connect Apple Health or Health Connect. Add a coach later if you want a programme written for you.
How does online training differ from in-studio?
In-studio students book a time slot and the coach marks attendance on the day. Online students get the same routine and log it at their own gym; the coach reviews the logs and adjusts the next block. Coaches can offer either or both.
Exactly what health data can my coach see?
Only what you share, per coach, in three separate categories. Training and sessions covers your assigned routine, your logged sets, session attendance, and session heart-rate summaries such as average and peak BPM. Nutrition covers your food diary. Body metrics covers the measurements you enter. Coaches never see resting data outside sessions or anything from other apps. You can switch any category off at any time, and it is used for coaching only.
How is student data handled under PDPA 2010?
Mason operates under Malaysia's Personal Data Protection Act 2010. You consent to each coach separately, you can withdraw that consent in the app, and you can request a copy or deletion of your data. Coaches may only use student data to deliver coaching.
How are coaches verified?
A coach uploads their certifications and any supporting credentials, and our staff review them by hand. Until that review is done, a coach is not listed in search and cannot take bookings.
