Launch Duolian from your Home Screen. Use your usual sign-in method if you already have an account, or follow the instructions to sign up or sign in.
Already using the App Store version? The beta replaces it, so you do not need to delete the app first. Keep the original files of important training videos.
02 / Try it
Try one training session
Start with a workflow you use regularly. You do not need to try every feature at once.
Allow the permissions you need
Allow camera and microphone access for recording, and select photo access when importing videos.
Start with posture correction
Open Training → Posture Correction, choose a technique, and follow the steps to practise and compare your movement.
Review the result and tell us how it felt
Was the feature easy to find? Did the workflow run smoothly? Was the result clear? We welcome all of this feedback.
Before each update, open TestFlight → Duolian → What to Test to see the focus of that build.
03 / Purchases
Try purchases without real charges
In Duolian downloaded from TestFlight, subscriptions and in-app purchases through Apple do not charge real money. Prices may still appear while you test the purchase flow.
Want to try membership?
Open Profile → Membership & Benefits, choose a plan and follow the Apple confirmation prompts to test a subscription.
Need more analysis credits?
Open Profile → Usage & Limits → Buy Credits and select a pack. You can buy additional packs as needed for testing without real charges.
