The best light meter apps for film photography in 2026
Starting priceFree
Free planYes
Lightme is the app film photographers recommend to each other, and the reason is respect for the craft. It opens to a meter, not a storefront. Its view shows the scene with your reading held steady, its companion logbook records the frame you just shot with the settings you used, and its whole design assumes you are holding a Leica or a Hasselblad in the other hand and want answers, not content.
Free covers the working meter, which is all most shooters need, and the paid extras are the kind of thing a photographer happily funds once: this is a one person craft tool in a category of utilities. If you shoot film on an iPhone, install Lightme first and learn metering on it; the more specialized apps below become upgrades for specific needs, not replacements.
What we like- Designed by a film photographer, with the film workflow in its bones: frame lines, zone style thinking and a reading that stays on screen, free to use, with a companion logbook app for recording frames and settings, spot and averaged readings through a clean, glanceable interface, a loyal following in the film community, which keeps it maintained and improving
Watch out for- IPhone centred, so Android shooters must look elsewhere on this list, advanced extras ask for in app purchases or the paid tier, incident metering needs a diffuser trick rather than a true dome, like all phone meters it inherits the phone camera's limits in very low light
Starting price$3.99
Free planNo
myLightMeter Pro is the value engineering pick: for $3.99 it does the two metering jobs, incident and reflected, remembers your cameras and lenses, and has been maintained for years by a developer who plainly uses it. The incident mode matters more than newcomers expect. Measuring the light falling on the subject, rather than the light bouncing off it, is how studio and portrait photographers have always worked, and this app brings a workable version of it to a phone.
It is not the prettiest screen here, and its density reflects its ambition. Spend one evening metering your home under different lamps against a camera you trust and you will learn both the app and its limits. After that, it is the meter most likely to still be on your phone, and correct, three cameras from now.
What we like- At $3.99 in June 2026 store checks, the cheapest serious meter here, incident metering using the front camera, plus reflected metering, in one app, saves readings per lens and camera, the memory film shooters with several bodies actually need, highly rated across years of updates, 4.8 stars in 2026 store data, works on both iPhone and Android, rare in this category
Watch out for- The interface is dense with information, which beginners must learn to read, incident readings through a phone camera are an approximation next to a real dome, no free version to test before buying, though the price is two coffees, low light sensitivity is bounded by the phone's camera hardware
Starting price$9.99

Pocket Light Meter is the outdoor photographer's entry. Spot metering a shadow and a highlight and placing them deliberately is the zone system in practice, and this app makes the phone do it with a tap, holding both readings while you decide. Then, when the light drops and the exposure stretches past a second, its reciprocity calculator applies the correction each film stock needs, the detail that saves night frames.
At $9.99 it asks you to be sure, and the surety test is simple: do you shoot slowly, on a tripod, in changing light, with films whose reciprocity tables you currently keep as screenshots. If yes, this is your app and the price is trivial against one ruined sheet of large format film. If no, Lightme's free meter covers your life.
What we like- Tap to spot meter any part of the scene, the control that high contrast film work demands, reciprocity failure calculations for the long exposures where film stops behaving linearly, logs readings with a photo of the scene, so your notes carry the evidence, at $9.99 it is a considered purchase that has stayed maintained across many iOS versions
Watch out for- The priciest stills app on this list, iPhone only, so Android film shooters are excluded, reciprocity data covers common films but your emulsion may differ, the log feature's organisation is basic next to Lightme's logbook

Cine Meter II is what happens when a cinematographer writes the meter. Stills apps think in shutter speeds; sets think in shutter angles, frame rates and filter stacks, and this app computes exposure in that language natively, then tells you the colour of the light as well, so mixed lighting stops being a surprise in the grade. Its maker's public accuracy testing is the most rigorous in this category.
Film photography readers should take from it only what they need. If you also shoot motion, or your stills work borrows cinema lighting, it is unmatched. If your world is a rangefinder and daylight, its power is ballast. The store price moves and bundles vary, so it is listed as See website, so check the live figure against the set features you will actually use.
What we like- Built by Adam Wilt for film and video sets, with shutter angle, frame rate and ND and filter compensation in the reading, reads colour temperature and green magenta shift, information stills meters ignore, false colour style waveform views help judge a scene's range, pairs with the Luxi diffuser for incident readings, from a maker who publishes his accuracy tests
Watch out for- Priced for professionals, historically in the mid twenties of dollars, with the current store figure best checked live, its cinema vocabulary is surplus for stills only shooters, iPhone only, like most of the serious tools here, the interface serves working camera crews, not casual users
#5
Lumu
Best for: Incident and colour metering with hardware
Visit lumu.com
Starting priceFree
Free planYes
Lumu is the bridge between this guide and the hardware meters it keeps recommending for critical work. The app is free and competent. The dome you plug in is the product: a proper incident sensor with colour measurement, in a pebble that lives on a keyring. For a hybrid shooter who lights portraits and shoots film between digital jobs, it replaces a $500 meter with something already in the bag.
Read the connector warning in the cons twice. The Lumu Power line grew up on Apple's Lightning port, and the phone world has moved to USB-C. Confirm the current model's compatibility with your exact phone before ordering, directly from Lumu. The concept is excellent and the installed base is loyal; the homework is yours.
What we like- The free app alone is a capable reflected meter with exposure, ambient and flash modes, the Lumu Power sensor turns it into a true incident, flash and colour temperature meter with its own calibrated hardware, measures the things phone cameras cannot: colour and flicker among them, the system is a favourite of cinematographers who travel light
Watch out for- The hardware costs about $299, a different universe from the $3.99 apps, the current Power sensor connects by Lightning, so USB-C iPhone owners must check compatibility carefully before dreaming, in app purchases gate some software features even after the hardware spend, as a pure free app it is outclassed by Lightme

LM-3000 represents the honest free tier: a maintained, well reviewed meter that asks nothing and reads light competently, including the white balance readout that helps when a room's colour is lying to your eyes. For a film shooter whose camera has no meter and whose budget is committed to film stock, free and current beats famous and abandoned.
Its ceiling is its generality. Nothing in it knows what film is. You bring the judgement about latitude, reciprocity and which part of the scene to trust, and it brings a number. Plenty of good photographs have been made with exactly that division of labour, and the June 2026 update date means its maker still cares, which in the free tier is the feature that matters most.
What we like- Free, well rated at 4.5 stars across thousands of reviews in June 2026 store checks, and updated in April 2026, so it is alive, measures ambient light levels and white balance information useful on shoots, a clean, quick interface for grab and go readings, the zero risk way for an iPhone shooter to test whether app metering suits them
Watch out for- A general light meter rather than a film photographer's instrument, so no reciprocity or logbook thinking, the website field points to its app store home, as the maker sells through the store rather than a product site, free apps in this category are often supported by ads or data light upsells, check the current listing, its maker is a small developer, so long term support is a hope, not a contract

Android film shooters are this category's second citizens, with most craft tools launching on iPhone alone, so a free Android meter with this one's record, highly rated, widely installed, freshly updated, deserves its line. It reads the light, shows lux beside exposure values, and costs nothing while you decide whether app metering fits your shooting.
Calibrate your expectations by your handset. Android phones differ wildly in their sensors, so test it against a camera meter you trust across a day of light before betting a roll on it. That ten minute check, which this guide recommends for every app here, matters most on the platform with the most hardware variety.
What we like- The Android pick from June 2026 store checks: 4.8 stars, over 100,000 installs, updated in May 2026, shows lux and exposure values together, bridging the lighting and photography readings, free, which suits the second phone or the meterless camera experiment, simple enough to hand to a student on a photo walk
Watch out for- Android only, obviously, and Android's fragmented camera hardware makes accuracy vary more by phone, a general meter first, so film specific helpers are absent, the website field points to its Play Store home, as with many small Android utilities, free tier support and ads depend on the current listing, so inspect before relying on it for a trip
How we chose
Apps had to meter light for exposure, not merely display lux for lighting design, and had to be alive: updated within the last year in the June 2026 store data we used, since abandoned meters rot as phone cameras change. We favoured tools built for film and cinema practice, spot readings, incident modes, reciprocity and filter maths, over general utilities, and stated platform limits plainly because this category is split hard by phone brand. Prices are app store figures from June 2026 checks; where a price moves or bundles vary, the entry says See website.
Calibrate before you trust
Whichever app you choose, spend ten minutes earning confidence in it. Meter the same evenly lit scene with the app and with a camera whose meter you trust, at several light levels from window light to a dim room. Note any consistent offset, a third of a stop bright, say, and either use the app's calibration setting or simply remember it. Phone cameras differ, and this small ritual converts a stranger's app into your meter.
Then remember what the number cannot know. A reflected reading is an average of whatever you pointed at, fooled by snow, beaches and black cats on black sofas exactly as camera meters are. Meter the part of the scene you care about, your subject's face, the shadow that must hold detail, and let the extremes fall where they may. That judgement, not the app, is metering. The app just does the arithmetic in better light than a dial.
Frequently asked questions
Are light meter apps accurate enough for film?
For colour negative and black and white, comfortably: their latitude forgives small errors, and checked comparisons put good apps within about a tenth of a stop of handheld meters. For slide film, meter carefully, bracket important frames, and prefer a dedicated meter for paid or unrepeatable work.
What is the difference between incident and reflected metering?
Reflected metering reads the light bouncing off the subject and is fooled by very dark or bright scenes. Incident metering reads the light falling on the subject, from the subject's position, and ignores its colour entirely. Portraits and studio work favour incident; wide outdoor scenes favour reflected spot readings of chosen areas.
Which app suits a complete beginner with a film camera?
Lightme on iPhone, for its film first clarity at no cost, and Light Meter Lux on Android while you learn. When a specific need appears, spot work, reciprocity, incident readings, the paid entries here answer it for the price of a coffee or two.
Why does my long exposure come out underexposed even with a meter?
Reciprocity failure: past about a second, film needs more exposure than the meter's linear maths suggests, differing by stock. Pocket Light Meter builds those corrections in. Otherwise, consult your film's data sheet and add the stated stops before blaming the app.
Can I use these apps for digital photography too?
Yes. Exposure is exposure: the reading sets any camera, film or digital. Cine Meter II and Lumu are in fact used mostly by digital cinema shooters. The film specific entries simply add the tools, reciprocity, logbooks, frame notes, that digital shooters no longer need.
