Tap once. Keep the whole class.
ClassStamp listens to a yoga class on your iPhone and hands back the flow: every pose, in order, with sides and the peak. The audio never leaves your phone.
Can I record a class?
You can listen to any class you take or teach. Getting permission to record is up to you: some studios and teachers ask that you check first, and some places require everyone's consent. When in doubt, ask the teacher. They usually love getting the flow.
Where does the audio go?
Nowhere. ClassStamp turns the class into words on your phone, finds the poses, then deletes the audio and the words. No recording is ever saved or uploaded.
What does ClassStamp keep?
Only the flow: the poses, their order, sides, phases, times and the style. Plus, when you fix a pose, the few words it misheard, so it gets that pose right next time. All of it stays on your phone until you share a card or delete it.
Other people's voices?
Never kept. Only pose names make it into the flow, and the words they came from are deleted with the audio.
Why is a pose grey?
ClassStamp wasn't sure it heard it right. Tap it to say it was right, change it, or remove it. Your fixes help it hear you better next time.
What does it need?
An iPhone on iOS 26 and a class taught in English. It works with the screen locked for up to two hours.
How do I delete my flows?
Delete a flow from Your flows, or delete the app to remove everything. There is no account and nothing is stored anywhere else.
How do I turn off the microphone?
On your iPhone, open Settings > Privacy & Security > Microphone and switch off ClassStamp.
