Intervalo vs AstroOwl

Intervalo is a dead-simple interval camera (intervalometer) for iPhone. Set how often it should take a photo, set how many photos you want — or leave it unlimited — tap start, and Intervalo shoots automatically until it's done. That's it. No ads, no account, no subscription, no in-app purchases. Completely free. WHAT IT DOES • Interval shooting from 1 to 60 seconds • Stop after 10, 25, 50, 100 photos — or run unlimited • Live countdown to the next shot and a running photo counter • Every photo saves straight to your Photos library A REAL CAMERA, NOT A TOY • Tap to focus and expose anywhere — using the iPhone's native autofocus • Pinch to zoom • Front and back camera • Flash: off, on, or auto BUILT TO STAY OUT OF YOUR WAY • Clean, single-screen design • No filters to wade through, no clutter • No data collection — nothing ever leaves your device Perfect for time-lapse source frames, monitoring a slow change over time, hands-free group photos, product shots, plants growing, skies moving, or any moment you want captured on a steady rhythm. Set it. Start it. Walk away. Intervalo handles the shutter.

AstroOwl is the night photographer's whole workflow in one app: find the night, frame the shot, prove the exposure, then drive the camera — without juggling three apps and an intervalometer at 2 AM in the dark. PLAN THE RIGHT NIGHT • Best-nights calendar scores the next several months for your location — moonlight, Milky Way visibility, darkness windows, weather, and light pollution, distilled to an honest verdict ("Fair — moonlight") instead of a mystery number • Milky Way core position, rise/set and darkness windows for any date • 33,000+ locations with offline time zones and measured/modeled sky darkness, including DarkSky International certified places • Scrub time with a knob and watch the whole sky move COMPOSE THE SHOT • Pick your camera and lens (or browse presets) and see the real field of view framed on the sky • Exposure recipes with NPF-aware shutter limits — start from presets matched to your subject (Milky Way, star trails, moon, timelapse…) and save your own • Simulate the result before you commit: realistic star trails, stacking, and noise for YOUR gear and settings • AR mode — hold the phone up and see targets over the live camera view SHOOT — HANDS OFF (Pro) • Connect your Sony Alpha camera over Wi-Fi and fire recipes directly • Multi-frame sequences run on the camera body itself — stacks, star trails, timelapses keep shooting even if the phone sleeps • Focus magnifier, session progress with ETA, automatic reconnect, and session recovery if anything drops mid-shoot • Your photos stay on your camera's card — they never pass through us FREE VS PRO The planner, composer, and simulator are free. AstroOwl Pro unlocks camera control and removes the free tier's monthly caps and watermark — as a subscription or a one-time lifetime purchase. Payment is charged to your Apple Account at confirmation; subscriptions renew automatically unless cancelled at least 24 hours before the period ends, and can be managed in your Apple Account settings. CAMERA COMPATIBILITY Camera control supports Sony Alpha bodies with built-in Wi-Fi (validated on the a7 IV). Planning, composing, and simulation work with any camera — or none at all. No account, no sign-up; the app works offline at dark-sky sites once you've planned. Terms of Use: https://astroowl.app/terms/ Privacy Policy: https://astroowl.app/privacy/
