What's New in Light Meter Wheel

1.2.5

September 15, 2026

Updated for iOS 27. Minor improvements.

User reviews

WOW, this is the best meter on the entire iOS store

So I tried out a bunch of free lightmeters and they had terrible interfaces, were plagued with ads and were slow to boot.

Then this one came along.

It loads super fast, goes from opening to working with a proper reading in 3 seconds flat. And this is on my super old iphone 5s. Goes from lock screen to reading in about half a second.

Its so damn accurate. Tested it against my digital camera, nailed the exposure every time.

It operates in lower light than the newest DSLRs. The d750 goes down to -2.75EV, this one goes to -4.0EV (which is basically blackness).

The UI IS AMAZING. The person who made this is clearly a photographer because it works so well. Smooth and responsive. Controls are simple, no extra fluff and the design is nice an modern.

The only issues I have with it is that it is apperature priority only. You set the apperature and then the shutter speed adjusts. And its a little hard on my small screen to adjust the exposure compensation. But those are super minor and everything else is perfect. UPDATE!! It has shutter priority now! Great app.

It's a shame this gem is buried in the app store. So worth the 2 bucks.

Good but…

Help is confusing and also Volume + and volume - have functions switched. Report a problem from app does not work either.

Simple, fast

Simple, fast and just works. I have looked for an app that shows me all possible exposures at the same time and is really simple. Which this one does and is.

Camera issue

This app hasn’t been updated in three years. The camera lens won’t view forward. Only views in selfie direction mode. Useless.

Essential for blackmagic!!

Have used Both apps from developer with much success. The spot metering is extraordinarily powerful when shooting video as it protects the highlights. It is very accurate and convenient. Criminally cheap!
