Plan every shot by the sun, moon and stars
Photo Expert tells you exactly where the light will be — golden hour, blue hour, moonrise, the Milky Way core — and then fires your camera for you over Bluetooth. Built by MIOPS for photographers who plan before they shoot.
What it does
From celestial math to a fired shutter
Every calculation runs on your device. Everything else — planning, weather, gear — is there to get you to the right place at the right minute.
Moon phases & widgets
Illumination, rise and set times, and the next 7 or 28 phases at a glance — on your home screen and on your Apple Watch.
Milky Way & astro modes
Track the galactic core, plan star trails, and get exposure guidance for sun, moon, star and Milky Way sessions.
Map planner
Drop a pin, drag the timeline and watch sun and moon lines sweep across the map. Includes an AR compass and a light-pollution overlay for dark-sky hunting.
Weather & conditions
Cloud cover, visibility and forecasts scored against your plan, so you know whether tonight is worth the drive.
MIOPS trigger control
Pair a MIOPS SMART+ over Bluetooth and run timelapse, exposure and interval ramping, plus lightning, sound, laser and rocket-launch sensor modes — and update its firmware.
Shot plans & calendar
Save locations, build shot plans, and get reminders for eclipses, supermoons and other events worth setting an alarm for.
Gear-aware suggestions
Add your bodies and lenses to a camera bag and Photo Expert tailors its shot recommendations to what you actually own.
Works offline, guest-first
All astronomy runs locally on your iPhone. The app is fully usable without ever creating an account.
