Frequently asked questions
Quick answers about the AI workout planner, gym logging and tracking your progress.
How does the AI workout planner work?
You tell the coach your goal, which days you can train, what equipment you have and your experience level. From that it builds a balanced weekly program in about a minute, with exercises, sets and suggested weights. Afterward you can tweak anything by hand or ask the coach to revise it.
Is Workout Buddy free?
Yes. The app is free. You can create an account, generate AI programs, log every set in the gym and track personal records without paying or entering a card.
Can I log workouts without wifi?
Yes. Once the workout screen is open, you can keep logging sets and using the rest timer even if the connection drops. Everything is stored on your phone and syncs to your account when you are back online.
Is Workout Buddy suitable for beginners?
Yes. If you are new to lifting, the coach chooses a sensible split, exercises and starting weights so you are not guessing on day one. As you get more confident you can take over any part of the program yourself.
Can I change my workout program?
Anytime. Swap exercises, rearrange days, add or remove sets in the editor, or describe what you need - for example an injury, less equipment or a new goal - and let the AI coach rebuild that part of the plan.
Does it support kg and lbs?
Yes. Choose kilograms or pounds in your profile and the whole app switches: workout logging, history and personal records all stay in the unit you picked.
Is there a light mode?
Yes. In your profile you can switch between light, dark or system. System follows the light or dark setting of your phone or computer, so the app matches the rest of your device.
Which languages are available?
Workout Buddy is available in English and Dutch. Guests get the language of their browser when possible; once you have an account you can lock English or Dutch in your profile, or leave it on automatic.
