The short answer
Fitbod for gym lifting, Aion for a week that moves
Pick Fitbod if you lift in a gym, use Android or an Apple Watch, or want an app with years of history and a large user base behind it. It picks your weights from your log. Pick Aion, which we make, if your week changes often, you train at home or outdoors, you want a calisthenics skill like a first muscle-up, or you would rather not pay for the plan. Aion's plan is free on iPhone, and its chat coach is a membership.

How this comparison was made
Both apps are compared on the same rows, using only what each says about itself. For Fitbod that means its US App Store listing, including the In-App Purchases section, its FAQ and the company facts on its site. For Aion it means the same kind of listing and our own pricing page. The ratings come from Apple's public lookup for the US store. We did not test Fitbod for this guide, and where its listing and its website give different prices, both are shown.
Aion is new and has no US ratings yet, so on track record the comparison is lopsided, and it should read that way. Where the two apps do different things, the rows say what each one does and leave the choice to you.

Pick Aion for a changing week, skills and a free plan
Aion Coach
Aion is ours, and it is new. It builds the week around your days, minutes, kit and goal, using only exercises the kit allows, and it progresses from your log: a session that goes well moves the next one up one small step, and two misses back it off. That plan costs nothing. The membership adds a chat coach that swaps a move, shortens a session or moves a day, and shows a before-and-after card so you choose Apply or Keep.
Where it is strong
- The whole plan is free, including progression and one swap per workout
- Ten calisthenics skill ladders with exit criteria
- Running and HYROX plans
- Injuries and limits you mention are remembered, and aggravating moves are eased or swapped
- A 594-exercise catalog, filtered by your kit
Where it falls short
- iPhone only; the listing shows no Apple Watch app
- The app is in English only
- New, with no US ratings yet
- The chat coach needs the membership
- No camera form check, and no nutrition or calorie tracking
- Price
- Plan free. Coaching membership $3.49 a week, $9.99 a month, $59.99 a year; the annual one opens with 7 free days
- Free
- The whole plan: every workout, every new week, the logbook, progression and one exercise swap per workout
- App Store rating
- Too new to have ratings yet (US)
- Platforms and languages
- iPhone. English.

Who should pick Fitbod
- You train in a gym with barbells, dumbbells and machines, and mostly want the app to choose the weights.
- You use an Android phone or a Wear OS watch. Aion runs on neither.
- You want an Apple Watch app. Fitbod's listing says it has one, and Aion's shows none.
- You value a long track record. Fitbod's site says it launched in 2015 and counts 15 million downloads; Aion has no ratings yet.
- You want an exercise library of more than 1,000 moves, each with multi-angle video.
- You would rather use the app in Portuguese or Spanish.
In any of those cases Fitbod is the better choice, and its 7-day trial is long enough to confirm it.
Who Aion suits better
- Your week changes, and you want a plan built around the days and minutes you actually have. Members can also ask for a shorter session or another day when the week moves.
- You train at home, outdoors or while travelling, with whatever is there. The plan only uses exercises your kit allows.
- You are working towards a skill: a first pull-up, a pistol squat, a handstand, a muscle-up or a front lever. Each of the ten ladders has exit criteria, so you know when to move up.
- You are training for a run or a HYROX race and want the strength work in the same plan.
- You do not want to pay for the plan. Aion's plan, progression included, is free; you pay only for the chat coach.
- You have an injury or a limit you want remembered, so that moves which aggravate it are eased or swapped.
How each one decides your next session
This is the core of both apps, and they go about it differently. Fitbod's listing describes AI-generated workouts that vary and balance your exercises, use non-linear periodization and learn from the edits you make to its recommendations. Its site adds that plans adapt to your goals, recovery, history and equipment. The weight on each set is the app's call, and your edits teach it.
Aion plans the week first, around the days, minutes, kit and goal you gave it, then moves each session from your log. When a logged session goes well, the next one goes up one small step. When you miss twice, it backs off. Those rules are part of the free plan. If the week itself changes, members ask the chat coach for a swap, a shorter session or another day, and see the before and after before anything moves.
Neither approach does anything clever without a log. Both are only as good as the sets you record, so whichever you choose, log what you actually did.
What a year costs
| Option | Aion | Fitbod |
|---|---|---|
| The plan on its own | $0 | $95.99 a year on Fitbod's site, or $79.99 for the App Store's yearly plan |
| Paid monthly for 12 months | $119.88 for the membership | $191.88 at $15.99 a month |
| Paid yearly | $59.99 for the membership, after 7 free days | $95.99 on Fitbod's site |
With Aion the membership pays for the chat coach. The plan and its progression cost nothing, and that is the biggest difference between the two apps on price. With Fitbod, the subscription is the plan.
Questions people ask
Is Aion better than Fitbod?
For gym lifting with weights chosen for you, Fitbod has the longer record, more platforms and a large rating base, and we would not claim otherwise. Aion is the better fit for a changing week, bodyweight skills, running or HYROX, and for anyone who wants the plan for free. We make Aion, so try both if you can.
Is Aion free?
The plan is: every workout, every new week, the logbook, progression and one exercise swap per workout. The chat coach is a membership at $3.49 a week, $9.99 a month, $59.99 a year, and the annual one opens with 7 free days.
Does Aion work on Android or Apple Watch?
No. Aion is iPhone only, and its App Store listing shows no Apple Watch app. Fitbod has Android, Apple Watch and Wear OS apps, so if you need any of those, Fitbod is the one.
Does Fitbod have a free version?
Fitbod's FAQ describes a 7-day free trial and then monthly or yearly plans at $15.99 or $95.99. Neither the FAQ nor the App Store listing describes a free plan after the trial.
Which is better for home workouts?
Both can work. Fitbod's listing says it supports home training with no equipment. Aion builds the plan only from exercises your kit allows, and its ten calisthenics ladders give bodyweight training a clear direction, so a pull-up bar goes a long way.
Can I use both?
You can, but two apps setting your training from two separate logs will disagree with each other. Pick one to own the plan, and log every session there.
