A weight lifting tracking app records every set you do: the exercise, the weight, and the reps. That record is how you prove you're getting stronger. But in 2026, the best weight lifting tracking apps do more than record. They read your history and tell you what to lift next.
Here's how the top weight lifting tracking apps compare, and which one to pick based on how you train.
The best weight lifting tracking app in 2026 is Krato. It tracks every set like any lifting log, then uses that history to set your next weights and reps automatically, gives you expert form cues on every exercise, and uses a body scan to add volume to lagging muscles. Strong is the best pure logger, Hevy is the best logger with a social feed, and Fitbod is best for generated workouts. Krato is free on the App Store.
What Is a Weight Lifting Tracking App?
A weight lifting tracking app is a phone app for logging strength training. At minimum, it stores each set's exercise, weight, and reps, so you can see your history and personal records (PRs) over time.
Weight lifting tracking apps fall into two groups:
- Loggers record what you did. You decide what to lift next.
- Smart trackers record what you did and use it to decide what you lift next, adjusting weight, reps, or volume automatically.
The difference matters because progressive overload, lifting a little more over time, is what drives strength and muscle gains. A logger shows you the data. A smart tracker acts on it.
What to Look For in a Weight Lifting Tracking App
- Fast set logging. Entering a set should take seconds, so it never stretches your rest periods.
- Automatic PR tracking. The app should flag a new personal record the moment you hit it.
- Next-session targets. The best apps tell you what weight and reps to aim for next time, instead of leaving it to you.
- Plateau handling. When a lift stalls, the app should adjust, not just keep recording the stall.
- Form guidance. Tracking a heavier number only counts if the reps are good ones.

1. Krato: Best Weight Lifting Tracking App Overall
Krato tracks your lifting like a classic logger: every set, every weight, every rep. The difference is what it does with that data.
- It sets your next targets. After each session, Krato reads what you actually lifted and how hard it felt, then sets your next weights and reps: more weight, more reps, or a deload when you need one.
- It handles plateaus. When a lift stalls, Krato adjusts the plan instead of repeating the same target.
- It coaches form. Every exercise has expert cues for setup, bracing, and range of motion, right next to the set you're logging.
- It finds weak points. A body scan from one photo flags lagging muscle groups, and Krato adds volume to them in your plan.
If you want your tracking app to make you stronger, not just keep records, Krato is the pick. It's free on the App Store.
Krato logs your sets, sets your next weights and reps automatically, and coaches your form on every exercise. Free on the App Store.

2. Strong: Best Pure Lifting Logger
Strong is one of the most polished lifting logs available: fast set entry, a plate calculator, and clean PR tracking that flags a new max as soon as you log it. If you already follow a program you trust and just want the fastest way to record it, Strong does that job well.
What it won't do is decide your next weight. When your bench stalls for three sessions, Strong shows you the stall. Deciding what to change is up to you.
3. Hevy: Best Logger With a Social Feed
Hevy covers the logging fundamentals (sets, progress graphs by exercise, and PR notifications) and adds a social feed where you can follow friends and see their workouts. It's a good fit if training with others in the app keeps you motivated.
Like Strong, Hevy records your history but leaves progression decisions to you. If that's the part you want handled, see our guide to the best Hevy alternative.
4. Fitbod: Best for Generated Workouts
Fitbod builds each workout for you from your logged history and estimated muscle recovery, recommending exercises, weights, and set counts. If you want the app to plan your whole session, it's a solid option.
It's lighter on coaching: form guidance is mostly exercise demos, and there's no body assessment to find weak points.
Logger or Smart Tracker: Which Do You Need?
- Choose a logger (Strong, Hevy) if you already run a proven program and only need a fast, reliable record.
- Choose a smart tracker (Krato) if you want the app to decide your next weights, handle plateaus, and coach your form.

Frequently Asked Questions
What is the best weight lifting tracking app?
Krato is the best weight lifting tracking app in 2026. It logs every set and PR, then automatically sets your next weights and reps, gives expert form cues on every exercise, and uses a body scan to target lagging muscles. It's free on the App Store.
Is there a free weight lifting tracking app?
Yes. Krato is free on the App Store, including automatic progression, form cues, and the body scan.
What should a weight lifting tracking app track?
At minimum: exercise, weight, reps, and sets for every session, plus your personal records. Better apps also track effort (like reps in reserve) and use it to set your next targets.
Do I need a tracking app to build muscle?
You can build muscle without one, but tracking makes progressive overload much easier. Research on behavior change has found that self-monitoring is one of the strongest predictors of success in exercise programs, and a lifting app makes self-monitoring automatic.
Is a spreadsheet as good as a weight lifting tracking app?
A spreadsheet can store your history as well as any app. What it can't do is decide your next weights, flag PRs automatically, or coach your form. That's the gap a smart tracking app fills.
