Publisher: AGUNA Wellness Ltd (RC 9590421) App: AI Gym Workout Planner: AGUNA, iPhone, iPad and Apple Watch, https://apps.apple.com/us/app/id6767250053 Guide · October 2026 # The AI workout app: what the AI does, and which one to pick Planning, adapting and meals. Here is what each AI fitness app actually automates, with prices read this week. Updated 18 October 2026 · Written by the team at AGUNA Wellness Ltd. We make one of the apps on this list, so we have said plainly where the others are the better choice. ## The short answer An AI workout app plans your training for you: the exercises, their order, the sets, the reps and the weight, and it changes the plan as you go. Fitbod is the most established. Alpha Progression and MacroFactor Workouts are good value for progression. AGUNA is the one that also plans your meals and adapts in the moment, when a machine is taken or the gym is packed. ## What does an AI workout app actually do? Almost every fitness app now says it uses AI. In practice the word covers three jobs, and only the first two change your training. - Planning. Picking the session from your goal, your days and what you trained recently. - Adapting. Changing the plan when reality does not match it: you missed reps, you skipped a day, the equipment is busy. - Talking. A chatbot that explains the plan. Nice to have, and the least important part when you are standing in a gym. ## AI fitness apps compared | App | Plans from your goals | Adapts during the session | Meals or calories | Price | | AGUNA | Yes, the whole week with rest days | Yes: Machine taken?, Busy gym? | Meal plan and photo calorie count | First full workout freeThen monthly or yearly, shown in your currency on the App Store | | Fitbod | Yes | Learns from your edits | Not built in | From $12.99 a month | | Planfit | Yes | Adjusts sets, reps and weight | Calories burned only | Free plan; paid from $11.99 a month | | Alpha Progression | Yes, on Pro | Sets weight and reps per set | Not built in | Free version; Pro $12.99 a month | | MacroFactor Workouts | Yes, rule based | Auto-adjusts | Separate MacroFactor app | $11.99 a month | | Freeletics | Yes, mostly bodyweight | Adjusts to feedback | Separate nutrition app | Plans from $34.99 | | Dr. Muscle | Yes | Updates every workout | Meal plan add-on | $49.99 a month | Prices are US App Store or official site prices read on 17 and 18 October 2026, and many apps show more than one price for the same plan. Check the listing before you buy. We make AGUNA. ## What AGUNA does, step by step - Your week, from your goals. Pick what you want (lose weight, build muscle, grow your glutes, get stronger) and the days you can train. AGUNA lays out Monday to Sunday with rest days built in. - An order for every session. Each workout trains two muscle groups, such as Chest and Shoulders, with six exercises in the order you do them, so you never stand there wondering what is next. - The weight, suggested. It remembers every set you log and suggests the next weight from what you lifted last time, so progress tracks itself. - Rest, timed. A rest timer runs between sets and calls you back when it is time. - Machine taken? Busy gym? One tap when someone is on the machine you need moves a free exercise up. One tap on a packed day turns the whole session into dumbbell work. - Edit anything. Swap an exercise, add a set, or change what each day trains. - Meals planned, calories counted. A meal plan from 15 regional menus that covers every country, plus Snap a meal: photograph your plate and AGUNA counts it. - Reminders and progress. Reminders to train and to eat, and a Trackers screen with your strength records going up. ## How to choose an AI workout app If you train in a busy commercial gym ### Pick one that adapts in the session A perfect plan that assumes the cable machine is free falls apart at 6pm. Look for a way to swap an exercise in one tap without losing the session. That is what Machine taken? and Busy gym? do in AGUNA. If losing weight is the goal ### Pick one that covers food too Training alone rarely moves the scale. Most AI workout apps leave food to a second app. AGUNA plans meals and counts a photo of your plate in the same place as your workout. If you already know how to lift ### Pick for progression depth Experienced lifters chasing numbers often prefer Alpha Progression, MacroFactor Workouts or JuggernautAI for their detailed progression rules. If you want a person ### Pick a human coaching app An AI does the planning. A coach watches your form and checks in. See our guide to the [best AI personal trainer apps](https://aguna.app/best-ai-personal-trainer-app), which compares both. ## Questions ### What is an AI workout app? An AI workout app builds your training for you. You give it your goal, your schedule and your equipment, and it picks the exercises, the order, the sets, the reps and usually the weight. The better ones change the plan when something changes, such as a missed session or a busy gym. ### Are AI workout apps worth it? For most people who do not have a coach, yes. The main value is not clever language, it is removing the decisions: what to train today, in what order, with what weight. That is where beginners lose time and confidence. ### What is the best AI workout app? It depends on what you need. Fitbod has the most refined workout generation and a large exercise library. Alpha Progression and MacroFactor Workouts are strong for progression on a budget. AGUNA is the pick if you want the workout and your meals planned together and an app that adjusts when the gym is busy. ### Do AI fitness apps replace a personal trainer? They replace the planning a trainer does, not the eyes on your form. If you need someone to watch you lift or keep you accountable by name, a human coaching app such as Future costs much more but gives you a person. ### Is there a free AI workout app? Several have free tiers, including Planfit and Alpha Progression. AGUNA gives you your first full workout free with no card, and the free AI workout generator on aguna.app builds a gym week without a sign-up. ### Does AGUNA work on Android? Yes. AGUNA is on iPhone, iPad and Apple Watch, and on Android through [Google Play](https://play.google.com/store/apps/details?id=com.aguna.app). ## Related guides - [Best AI personal trainer app](https://aguna.app/best-ai-personal-trainer-app): AI coaches against human ones - [Best personal trainer app for beginners](https://aguna.app/best-personal-trainer-app-for-beginners) - [Best AI workout app, compared](https://aguna.app/best-ai-workout-app) - [Best workout app for beginners](https://aguna.app/best-workout-app-for-beginners) - [Free AI workout generator](https://aguna.app/ai-workout-generator): your gym week in 30 seconds - [Gymtimidation](https://aguna.app/gymtimidation): why the gym feels scary and what helps ## Your workout and your meals, planned from your goals.
