## Most critical reviews (9 lowest-rated)

### 1/5 — Does not work on iPhone 12

*2021-11-03*

This app does not work on iPhone 12 and I fully intend to demand a refund and have my credit card refused to charge.

### 1/5 — Valores em metrô não funciona

*2018-07-25, version 8.0*

Não consegui os valores em M somente em ft 😑😑😑😑😑😑

### 2/5 — It works in meters only once and stop

*2020-04-22, version 8.0*

Whatever the value I choose the App don’t show me in meters and the flash power shows the limit of 1/64, my flash works until 1/128.

### 3/5 — Good app, but ...

*2019-11-09*

Would’ve given 5 stars if it was possible to set power level down to 1/256 as many strobes offer this level of power adjustment. Otherwise, perfect app.

### 3/5 — Update?

*2017-06-21, version 7.0*

Update?

### 5/5 — Works Great!

*2022-01-05*

Running great on the iPhone 13 Pro MAX, and assists me in numerous occasions when it comes to photography setup in various situations. Not sure what the iPhone 12 guy is talking about- he’s probably very confused on how to open an application without a home button? I could even help him it’s that easy, but he may lack the mental fortitude to understand how to press buttons? I certainly have enjoyed the app and its complex calculations.

### 5/5 — Wonderful app

*2016-11-14*

I would love to see an option to select flash power divided into 1/3 or 1/2

Thank you for making this app. This makes the guesswork from film much easier.

### 5/5 — Works great!

*2014-08-13*

This is exactly what you need if your off-camera manual flash doesn't assist in these calculations. This takes the guess work out of determining flash to subject distance, aperture, or power. Just enter your flash's guide number and you're good to go. Thank you!

### 5/5 — Better than expected

*2013-06-14*

Very handy for pre-planning a major shoot.
