The Best Light Meter Apps for Film Photography in 2026

Quick verdict

For Android film photographers who want serious depth (Zone System, large format, slide film, every analogue correction): Zone Light Meter. For iOS shooters who want the cleanest paid app: myLightMeter Pro. For iOS casual use: Pocket Light Meter or Lightme. For calibrated incident metering with a hardware accessory: Lumu. For anyone who wants the most minimal free tool: FilmMeter.

Most film photographers will eventually want more than one. A phone meter for everyday work, a handheld for studio, and a notebook for anything that matters.

The full table

1. Zone Light Meter

Free on Android (iOS in development), built around the Zone System with 693 film stocks, multi-spot biasing, false-color HDR, and first-class corrections for reciprocity, bellows, IR filters, and expired film. Bracketing wizards, shot log with CSV export and Lightroom preset, no ads, no account, no tracking.

The trade-off: more features means more to learn. The app is designed to teach as you go (every modal has a help icon explaining what it does and why), but it is not the simplest tool in this list.

Pick it if: you shoot Android, you work with the Zone System or want to, you do large format or slide film, you do long exposures, you want a shot log that matches scans back to frames.

2. Pocket Light Meter

The longest-running phone light meter, on iOS since 2009. Free with banner ads (which several reviewers have flagged as creating a blind spot directly on the spot meter reticle), $1.99 or $5.99 IAPs remove ads or tip the developer. iOS at $9.99 paid tier.

That fifteen-year run matters. A lot of film photography forums treat Pocket Light Meter as the default recommendation because it is what everyone was already using when those communities formed. Reciprocity uses per-stock factors. Spot, average, and an incident approximation are all there.

Pick it if: you shoot iOS, you want the most familiar option, the Zone System and large format are not part of your workflow.

3. myLightMeter Pro

$3.99 on iOS, one-time, no subscription. David Quiles built it to feel like a handheld meter on a phone screen: analogue dials, clean layout, Sekonic aesthetic. It works. Photographers who want a one-time payment and a focused tool tend to reach for this one.

What it does not do: Zone System in any systematic way. Multi-spot is not in the workflow. Reciprocity is manual. The film catalogue is thin. The same developer ships LightMeter on Android, a narrower subset of the iOS feature set.

Pick it if: you shoot iOS, you like the Sekonic aesthetic, and you want a paid app with a one-time fee instead of a subscription.

4. FilmMeter

Free, cross-platform, no paywall, per the developer's stated position. It came up on r/AnalogCommunity in early 2026 as the recommendation for shooters who want minimal. Core metering workflow, nothing else added.

Pick it if: you meter outdoors in normal light and do not touch the Zone System, large format, or expired stock.

5. Lightme

Free, cross-platform, tip-jar IAPs. Rated 4.9 on iOS and well-reviewed for everyday use. More polished than the bare minimum, without getting into Zone System or correction territory.

Pick it if: you want a free app that feels finished and you do not need deep analogue-correction workflows.

6. Lumu Light Meter

Free app, but it is a companion for the Lumu Power 2 hardware. The accessory plugs into the phone and provides calibrated incident metering, with cine workflow (footcandles, T-stops, frame rate). Hardware ranges from $249 to $499 depending on tier (Lite, Power, Pro).

Pick it if: you want truly calibrated incident metering without carrying a Sekonic, you shoot motion picture film professionally, or you want a single phone-attached tool for color temperature and flash metering too.

What about handheld meters?

Phone meter apps and handheld meters are not the same product. Phone meters are reflective by default, share the phone's optics and exposure, and depend on calibration. Handheld meters like the Sekonic L-308X, L-478DR, and L-858D are incident-capable, factory calibrated, and physically durable.

For studio and serious cine work, a handheld is still the right choice. For everyday film work, a calibrated phone meter is within a third of a stop and weighs nothing extra.

What to skip

Several light meter apps in the App Store and Google Play target casual digital photographers rather than film shooters: they read in EV, lack film stock libraries, and have no concept of reciprocity or bellows. Anything that does not explicitly support film stocks and ISO inputs in the 25-3200 range is not built for film work.

Avoid apps with subscription models for this category. Light metering is not a server-side service; there is no recurring cost that justifies recurring revenue. Reviewers have repeatedly pushed back against subscription pricing in the analogue photography niche.

How to choose

1. What platform do you shoot on, today?
2. What is your most common difficult scene? (Backlit, snow, contrasty slide, long exposure, large format close-up)
3. Do you log your shots?
4. Do you want a tool that teaches you, or a tool that just gives you a number?

Those four answers tell you the right app. For most serious Android film photographers, the answer is Zone Light Meter. For iOS, it depends.
