Lensage: Astro & Photo Planner

Plan the shot before you leave. Saved spots, a Milky Way night calendar, golden-hour alerts, AR sky view, 13 calculators, 33 recipes. Free, no subscription.

Lensage plans the light before you leave — sun, moon, and Milky Way for your exact spot (current or saved), golden hour to the minute, a night calendar that rates every night for the Milky Way, and the thirteen calculators a landscape and astro shooter reaches for in the field. On-device math on iPhone, iPad & Apple Watch.

Open Lensage. See tonight's golden hour, moon phase, and Milky Way position on the Tonight card. Tap once. Get the number. Go shoot.

WHAT YOU GET

• Depth of Field & Hyperfocal — front-to-back sharpness in three taps. • NPF + 500 Rule — how long you can expose before stars trail. • Milky Way Exposure & Visibility — when the core rises, where it sits, whether tonight is worth the drive. • Exposure Equivalence — translate ISO 100, f/8, 1/60 into every shutter/aperture/ISO combination. • ND Filter Calculator — six stops, ten stops, fifteen. • Field of View — what 24mm sees on full frame vs. APS-C vs. your phone. • Focus Stack, Star Trail, Time-Lapse, Sun & Golden Hour, Moon Phase. • Saved shooting spots, a Milky Way night calendar, golden hour / blue hour / Milky Way alerts, and an AR sky view. • 30+ Cheat Sheets and 140+ camera bodies with sensor size and CoC preconfigured.

FREE

Everything is free — every calculator, planner and field theme, including Indigo for twilight and AMOLED with true black and red-shifted accents that protect your night vision under the Milky Way. No subscription, no paywall, no account. Lensage is supported by a single, unobtrusive banner.

WHY LENSAGE

For photographers who'd rather shoot than study an app. Every screen answers one question. The numbers are big, the inputs collapse, the math is honest — NOAA solar algorithms, Jean Meeus astronomy chapters 22 and 48 — but you never have to see it unless you want to.

PRIVACY

Your photography math runs on your device; solar and lunar positions are computed locally. The app shows one banner ad served by Google AdMob — ads are not personalized and Lensage never asks to track you across other apps or websites.

ON YOUR WRIST — APPLE WATCH A native Watch app, not a port: golden hour countdown, moon phase, and tonight's Milky Way at a glance during setup — plus depth-of-field, ND and golden hour calculators and watch-face complications.

Built for iPhone, iPad, and Apple Watch. iOS 17 or later.
