Fitness tracker app that shows your progress
The GrabGains fitness tracker app keeps track of every workout, set and personal record, and turns them into progress you can actually see: volume per week, strength per exercise, consistency over the months and which muscle groups get enough work. No wearable needed, just your phone.

Fitness app for tracking workouts
Every workout logged, set by set
Start a planned Smart Workout or your own routine and log weight and reps as you go. Your previous session is one tap away while you train, and in your exercise log every set sits next to what you lifted last time, so tracking your workouts takes seconds and each session builds on the last.
- Planned workouts or your own custom routine
- Your previous session one tap away, set by set
- Warm-up sets kept apart from working sets
Fitness app for tracking progress
See your strength grow per exercise
Every exercise has its own history with max weight, volume and reps per session. The app calculates an estimated one-rep max from your best set, so you see your strength develop without ever testing a max.
- Charts for max weight, volume and reps
- Estimated 1RM from your best set
- Personal records with weight, reps and date
Consistency tracking
Streaks that make consistency visible
Progress starts with showing up. The training calendar shows every day you trained, and your weekly streak counts how many weeks in a row you have trained.
Along the way, milestones such as your first rep, a new record or never skipping leg day are marked with an achievement.
- Weekly streak and workouts per month
- Training calendar with every completed workout
- Achievements for milestones in your training
Muscle Zone Tracking
Know which muscle groups need more work
Your logged sets are turned into volume per muscle group. Grow shows how many sets each muscle group has had in the last seven days, measured against the growth zone for your level, and every exercise shows which muscles it works, front and back.
- Sets per muscle group against the growth zone for your level
- Target muscles shown for every exercise
- Priority Zones to focus on the two areas you want to improve
Monthly Deep Dive
Your month in numbers
Once a month, the AI coach sums up your training: total volume, training time and number of workouts compared with the month before, how your sessions felt and where your sets went. It ends with a concrete focus for the weeks ahead. The Monthly Deep Dive is part of GrabGains Pro.
- Volume, training time and workouts vs last month
- How your sessions felt, at a glance
- A clear focus point for the weeks ahead

What the best fitness tracker app should do
The best fitness tracker app for strength training does more than count workouts. It records what you lifted, compares it with last time and turns it into progress you can see: per exercise, per muscle group and over the months. That's what makes tracking worth the effort.
Consistency
Streaks, a training calendar and workouts per month show how consistently you train over the weeks and months.
See Smart WorkoutsProgress per exercise
Charts for max weight, volume and reps, plus an estimated one-rep max calculated from your best set.
Weight training appMuscle Zone Tracking
Volume and distribution per muscle group, so you see which body parts get too little work.
Plans built around your Priority ZonesMonthly Deep Dive
A monthly review of your volume, training time, workouts and how your sessions felt, compared with the month before.
Meet the AI coachStronger together
Follow friends, share workouts and celebrate personal records together. Leaderboards for the bench press, squat and deadlift and for consistency keep you sharp.

Wearable app, notes app or GrabGains
A wearable app is great for steps and heart rate, but tells you little about your strength training. A notes app stores your sets, but calculates nothing. GrabGains is a fitness tracker built around what you do in the gym.

Frequently asked questions
What is the best fitness tracker app?
For strength training, the best fitness tracker app logs every set, rep and weight quickly, shows your previous performance while you train and calculates your progress for you. GrabGains does all three and adds volume per muscle group, streaks and a monthly review of your training.
Is the GrabGains fitness tracker app free?
The app is free to download and new accounts get 14 days of Pro. Logging workouts, your previous session, personal records, the exercise library, the feed and leaderboards stay free after that. The full exercise history with charts and estimated 1RM, the muscle maps in Grow, generating Smart Workouts and the AI coach with its Weekly Review and Monthly Deep Dive are part of Pro. Pro prices for your country are shown in the App Store and on Google Play. Subscriptions renew automatically until you cancel in your App Store or Google Play account settings, at least 24 hours before renewal.
Do I need a smartwatch or wearable?
No. You log your workouts in the app on your phone, so you don't need a smartwatch or other wearable to track your training and progress. The app does not connect to a smartwatch and does not count steps or measure heart rate: it is built around sets, reps and weight.
How does the app show my progress?
Per exercise you see max weight, volume, reps and an estimated one-rep max over time. On top of that, the app shows your weekly volume, volume per muscle group, personal records, your streak and a Monthly Deep Dive.
Can I track my body weight?
Yes. In the Body tab on your profile you log your weight and, if you like, your body fat percentage, and you see how your weight trends over time. Body weight tracking is free.
Is the fitness tracker available on iPhone and Android?
Yes. GrabGains is available on iOS and Android. Download it from the App Store or Google Play and start with 14 days of Pro for free.
Does the app track which muscle groups I train?
Yes. With Muscle Zone Tracking you see your training volume and distribution per muscle group, so you notice which muscle groups are getting too little attention.
