How do I join the GymBook ・ Strength Training TestFlight beta on watchOS?
First, download Apple's official TestFlight app from the App Store on your Apple Watch. Then return to this page and select "Get Early Access" above. Your device will automatically open TestFlight and prompt you to accept the developer's beta invitation. Tap "Accept" and then "Install" to start testing GymBook ・ Strength Training. If it says "This beta is full", tap "Get Slot Alerts" to be told when a slot opens.
Is testing GymBook ・ Strength Training on TestFlight safe and free?
Joining is free, and TestFlight is Apple's official beta testing service. Apple reviews beta builds before they can be shared through a public link, and beta apps run in the same sandbox as App Store apps, so they can't access your data without your permission. Betas can still have bugs. The beta is made by Appwise GmbH.
Do in-app purchases or subscriptions cost real money during TestFlight beta testing?
No. In TestFlight, Apple connects all transactions to its free Sandbox environment. Any in-app purchase, pro feature tier, or subscription inside GymBook ・ Strength Training will display "[Environment: Sandbox]" and costs $0.00. Your Apple Account or credit card will never be billed for purchases made within a TestFlight beta build.
Does the GymBook ・ Strength Training beta work on Apple Watch?
If the build includes a watchOS app, you install it from the TestFlight app on your paired iPhone. TestFlight shows the minimum watchOS version for each build.
What should I do if the GymBook ・ Strength Training TestFlight beta says "This beta is full"?
A TestFlight beta can have up to 10,000 external testers, and developers can set a lower limit. Spots open up again when testers leave the beta or when Appwise GmbH removes inactive testers, which often happens around a new build. Select "Notify Me" on this page for an email the moment a seat opens (CodeWing Plus) or follow our free Telegram channel. You can also find similar betas in the Health & Fitness category.
Will installing the beta replace my current App Store version of GymBook ・ Strength Training, and will I lose my data?
Installing the TestFlight beta will replace the App Store version on your Apple Watch, but all your local app data, documents, logins, and configurations are safely preserved. If you ever want to switch back to the stable public release, you can simply redownload GymBook ・ Strength Training directly from the App Store at any time without losing your data.
How long does a TestFlight beta build last before it expires?
Each TestFlight build has a maximum lifespan of 90 days from the day the developer uploaded it to Apple. You can see the countdown days directly beneath GymBook ・ Strength Training's title in your TestFlight app. Developers regularly release new builds with improvements, which automatically resets the 90-day timer so your testing is uninterrupted.
How do I send feedback or report bugs for GymBook ・ Strength Training?
You can send feedback directly to Appwise GmbH by taking a screenshot while using GymBook ・ Strength Training and tapping "Share Beta Feedback", or by opening TestFlight, tapping GymBook ・ Strength Training, and selecting "Send Beta Feedback". You can include notes, screenshots, and system logs to help the developer fix issues before the official App Store launch.
