Photometer downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Photo & Video apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Photometer
There used to be an entire industry based on red lights, that would have nothing (or very little) to do with scarcely dressed women - they called themselves photographers.
If you remember these times you probably call at least one of the mechanical wonders your own, which are today known as analog cameras and the best of them didn't have something called "in-camera metering" on the feature list.
Well, here's an App for you - dust off your Leicas, Hasselblads and Linhofs or whatever brand you fancy, stop looking for Mercury batteries and worrying about Selenium, what you need is already in your pocket!
Photometer will turn your iPhone into a reliable Exposure Meter, a modern interpretation of what it should be in times of retina displays and touch screens - for old times sake we have included a classic skin that feels and behaves just like the real thing.
Now go out and start taking pictures with grain, not noise!
Feature List
- digital light meter
- aperture or time priority
- 10% steps towards the next value (white bars)
- color measurement
- lock measurement (grid and lock icon)
- underexposure warning (only grid)
- modern and classic view
