Terms of Use

These terms apply to the GymDex iPhone app, published by Jude Okun. Your use of the app is governed by Apple’s Standard Licensed Application End User License Agreement together with these terms. Where the two conflict, Apple’s agreement prevails.

Price and purchase

GymDex is free to download and includes your first five machines. A one-time in-app purchase, Full Access, unlocks every machine. It is not a subscription and never renews. Apple processes the payment, and refunds are handled by Apple under its policies. Full Access is tied to your Apple Account: restore it on another device from Settings › Restore purchase. Machines you have already added stay unlocked whether or not you buy.

Training safety

GymDex is a reference and logging tool. It is not medical advice, and it does not replace a qualified coach or doctor. Check with a doctor before you start a new exercise programme, especially if you have an injury or health condition. Stop if you feel pain, dizziness or shortness of breath. Follow your gym’s rules and the manufacturer’s instructions on each machine. You train at your own risk.

Machine identification

Scanning identifies a machine from its instruction plate or appearance, and it can be wrong. Always check the machine itself and its plate before you use it. Weights on machine stacks are not comparable between manufacturers or gyms, so treat logged figures as your own notes, not as a standard.

Your record

Your training record lives on your device and you are responsible for it. Export backups regularly, especially before deleting the app or changing phones. We cannot recover data that was never exported.

Content and licences

Exercise data and animations come from ExerciseDB, and the on-device recognition uses open-source models. The app lists their licences and attributions under Settings › About & legal. Gym equipment names and brands belong to their owners. GymDex is not affiliated with or endorsed by any gym or equipment manufacturer.

No warranty

The app is provided “as is”, without warranties of any kind, to the extent the law allows. To the extent the law allows, Jude Okun is not liable for any injury, loss or damage arising from your use of the app or from relying on its content. Nothing in these terms limits rights you have under consumer law that cannot be excluded.

Changes and contact

If these terms change, we will update this page and the date above. Questions: jude.okun@gmail.com.
