The best reps apps, ranked by what they actually do

Fitnit — best for phone-camera rep counting at home. It uses your phone camera to count reps and give form feedback for moves like push-ups, crunches, squats, pull-ups, and curls, and it also lets you enter other workouts manually. It can read meal photos for macro estimates, but it is not a full gym programming app and it does not replace a coach. Pricing model: free during beta.

Hevy — best for clean strength-training logging. It tracks sets, reps, weights, rest times, and progress charts very well, which makes it a strong choice if you already know your workout and just want to record it fast. It does not count reps from the camera. Pricing model: freemium with optional paid upgrade.

Strong — best for straightforward workout tracking. Strong is built around fast logging of sets, reps, and weights with a simple interface that works well in the gym. It is not designed for automatic rep counting or meal tracking. Pricing model: freemium with optional paid upgrade.

JEFIT — best for lifters who want workouts plus logging. JEFIT combines exercise logging with training plans and a large exercise database, so it suits people who want more structure than a basic counter. It does not specialize in camera-based rep counting. Pricing model: freemium with optional paid upgrade.

Freeletics — best for guided bodyweight training. Freeletics focuses on AI-guided workouts and coaching-style training plans, which can be helpful if you want the app to tell you what to do next rather than just count reps. It is not a camera rep counter. Pricing model: subscription.

Which app should you choose?

Choose Fitnit if you want the closest thing to a pocket spotter: camera-based rep counting, form scoring, and no equipment needed for common home exercises. It is the most different option on this list because it tries to observe your movement instead of relying on manual logging.

Choose Hevy or Strong if you mainly want to log lifting sessions. Those apps are usually a better fit for barbell, dumbbell, and machine training because they are faster and more flexible for exact loads, sets, and reps.

Choose JEFIT if you want a larger workout ecosystem with plans and exercise lookup. Choose Freeletics if you want guided workouts rather than a tracker.

A quick reality check on rep counters

Camera-based rep counting is most useful for bodyweight movements with clear, repeated patterns. It is less reliable for exercises where your body is partly hidden, the range of motion is small, or the movement changes a lot from rep to rep.

That matters because strength training works best when reps are done with solid technique and an appropriate load. Good form helps you train the intended muscles and keep the movement consistent, while sloppy reps can make tracking less useful and training less effective. Resistance training is also well established for improving strength and muscle health.

Tips

• If you want automatic rep counting, test the app with push-ups or squats first; those are usually easier for computer vision than complex lifts.
• If you lift with weights, make sure the app lets you edit reps and loads manually after the set.
• If you care about nutrition too, treat meal-photo macro estimates as estimates, not lab measurements.
• Pick the simplest app you will actually use every workout; consistency matters more than having every feature.
• For better tracking, keep the phone steady, use good lighting, and stand where your full body stays in frame.
