Trackist vs FitnessAI: today’s workout or a whole plan?

Which one should you pick?

Pick FitnessAI if you want short sessions, an Apple Watch or Android app, and a clear answer to what you lift today.

Pick Trackist if you want to see the weeks ahead, and want the plan to react when a session was too hard or your shoulder hurts on the bench.

What FitnessAI does well

FitnessAI keeps the gym simple. Open it and today’s workout is ready, with the sets, reps and weight already chosen. Tap a set to log it. The app tells you how long to rest and adjusts the difficulty for next time. Its site advertises sessions of 5 to 30 minutes, which suits a lunch break.

It works with the equipment you have, at the gym, at home or on the road, and you can swap exercises. Guided videos and muscle visuals show you the form. It runs on iPhone, Apple Watch and Android, and syncs workouts with Apple Health. On the US App Store it has a 4.7 rating from about 56,000 ratings.

It also has extras Trackist does not:

• a real person: you can message the FitnessAI team in the app when you need advice
• challenges: every workout earns a point, and the top of the leaderboard wins prizes
• BodyScan: a 3D scan with the iPhone camera that estimates body fat and lean mass, sold as a $9.99 a month subscription

The US App Store lists several memberships: $9.99, $14.99 or $19.99 a month, $59.99 or $89.99 a year, plus weekly and quarterly options. FitnessAI’s own site shows its Premium Plan at $89 a year.

Where Trackist is different

You see the plan, not only today

FitnessAI is built around the workout in front of you. Trackist is built around the plan. From 14 questions about your goal, experience, equipment, joints, schedule, session length and age, it writes a plan of 4 to 12 weeks on the weekdays you pick. You see the training week and the shape of the whole plan before you start.

Above each exercise, Trackist suggests today’s weight from your last session, in steps that fit the equipment: 2.5 kg on a barbell, 2 kg on dumbbells. In a plan of 6 weeks or more, the last week is a deload, a lighter week at 60% of the sets, so you recover before the next plan.

You can tell it what went wrong

• Too hard or too easy: said once, it is noted. Said again in a later week, Trackist rewrites the day or rebuilds the rest of the plan.
• Pain: tell it the exercise, the joint and how bad it is. You get a swap that trains the same muscle, picked by the coach or chosen by you from the library. A shoulder that hurts when pressing still gets rows and pulldowns. Trackist stores the limitation, so later plans avoid it.
• The plan ends: you get a recap, and the coach writes the next plan from how this one went, including what you skipped and where you stalled.

It shows where you stand

The Strength Score reads 90 days of loaded squat, hinge (deadlifts and similar), push and pull sets, and gives you a score out of 100 and a Strength Age. Momentum is a reading out of 100 that builds as you train and fades slowly when you miss sessions, without resetting like a streak. Trackist also tracks your body weight and 9 measurement sites.

Compare them side by side

We checked prices and limits on the US App Store and on each app’s own site in September 2026. Both change, so the App Store has the final word.

What Trackist does not have

• No Android app yet, and no Apple Watch or iPad app.
• No exercise videos. The library has 201 exercises with written form cues and a muscle map.
• No offline logging. Logging needs an internet connection.
• No human to message, no challenges or prizes, and no body scan.

Which one fits you

FitnessAI, if you want to open the app, see what to lift and be done in half an hour, or you train with an Apple Watch or an Android phone.

Trackist, if you want to know what the next 8 weeks look like, and want the plan to change when you tell it something is wrong. Read how an AI personal trainer adjusts your plan, or pick a split and see how Trackist runs it for 4 to 12 weeks.
