A person reads every email.

Any fully manual or semi-manual camera. You describe the body's shutter ladder and each lens's aperture range and click step, and Obtura only ever recommends settings that exist on your gear — if f/1.7 is not on your lens, it will never suggest it.

Yes, completely. Metering, the exposure solver and the on-device model that reads your description all run on the phone, so the app behaves the same in airplane mode as it does on Wi-Fi. Once Obtura knows you have paid it keeps honouring Pro offline — a lost connection is not a refund.

Because that is the light meter. Obtura reads the scene's luminance through the lens to derive an EV, and renders the previsualisation from the same live frames. Images are processed as they arrive and are not written down; a frame is saved only when you log a shot yourself, and it stays on the device. Refuse the permission and the app says it cannot meter rather than failing quietly.

Pro removes the weekly limit on coached intents. The light meter, previsualisation, the shot journal, calibration and your camera profiles are free and unlimited without it; the one metered thing is a coached card that arrives with settings on it, which is capped at three per rolling seven days on the free tier. A scene the solver declines to answer costs nothing. Pro is sold monthly, annually, or as a one-time lifetime unlock, at prices shown in the App Store.

Open the camera chip at the top of the viewfinder, tap Obtura Pro, then Restore purchases, signed in to the same Apple Account you bought with. There is no receipt to find and no account with us to log into. If the store has no purchase on that Apple Account it tells you so rather than failing quietly, and once Pro is found the row stops being offered.
