One photographer, one camera,
and a coach that reads the settings.

Max Camacho

Founder and developer of Aperi. The company behind it is RecompFit LLC, the seller of record on both app stores. There is no team page because there is no team: the app, the relay that meters the coach, this site and the camera protocol work are one person's.

Why it exists. Every photography coach I could find works on the picture after the fact: export it, upload it, remember what you shot it at, read a critique. By then the light has changed and the moment is gone. I wanted the coach standing next to the camera while I shoot: reading the actual shutter, aperture, ISO and focus mode from the body, looking at the frame I am about to take, and telling me in a sentence or two what to change before I press the button again.

Why it took reverse-engineering. Sony publishes a camera remote SDK for Windows, macOS and Linux, and nothing for phones. So Aperi speaks the camera's own USB protocol, PTP with Sony's extensions, worked out one device property at a time against an A7 V on a desk, and reaches the same body over its Wi-Fi through an encrypted tunnel so the phone can stay in a pocket. That is also why the compatibility list on the home page is so blunt: the A7 V is the body it was built on, and the others are exactly as tested as it says.

What I promise. Aperi never touches your photograph. It does not generate, retouch or edit anything. When you ask the coach, the frame goes to the AI provider and comes back as words; our relay keeps none of it, and the privacy policy says exactly what it does keep.
