Rung — Support

Rung is a hangboard training app for iPhone and Apple Watch, made by one person. There is no support desk and no ticket queue — mail reaches the developer directly.

Reporting a problem

If you are on a TestFlight build, the fastest route is the TestFlight feedback button — it attaches a screenshot and the exact build automatically. Otherwise, including the following turns a report into something fixable:

• What you expected, and what happened instead.
• Whether it happened on iPhone, Apple Watch, or both.
• iOS / watchOS version, and the Rung version from Settings → About.
• Which routine was running, and at which phase — hang, rest, transition, set rest.
• A screenshot, if there was anything to see.

Things that come up

The watch shows different numbers from the phone

Open the routine list on the watch and tap Sync from iPhone with the phone nearby and unlocked. If the routine still looks wrong afterwards, that is a bug worth reporting — say which routine and which numbers.

A workout did not reach Apple Health

Check that Rung is allowed to write workouts: iPhone Settings → Health → Data Access & Devices → Rung. Sessions are written when they finish, so a session stopped early is logged in Rung but may not appear in Health.

I paid for Pro and it is not unlocked

Settings → Restore Purchases, on the same Apple Account you bought it with. Pro reaches the watch from the phone, so give the two a moment near each other. If it stays locked, mail the receipt Apple sent you and it will get sorted.

How do I get my data out?

Settings → Export Complete History gives you CSV and JSON of every session and progress event, with no account and no date limit. It is yours; nothing about the export goes through the developer.

How do I delete everything?

Settings → Delete All Data clears local storage and the iCloud copy. Deleting the app alone removes only the on-device copy — use Delete All Data first if you want the iCloud copy gone too. Workouts already written to Apple Health stay there and are removed in the Health app.

What Rung is not

It is a training app, not a medical service. Nothing in the Health Hub, the rehab protocols or the Science Library is a diagnosis or a treatment plan. If a finger hurts in a way training does not explain, that is a question for a physiotherapist or a doctor, not for an app.

Privacy

Rung has no account, no server and no analytics. The full privacy policy explains what is stored and where — the short version is that it stays on your device and in your own iCloud.
