This app does not work the calculations are way off They’re not even close to where they should be. Don’t bother with this app it does not work. As a matter of fact I want my money back. ### 1/5 — Not compatible with IPhone *2019-03-24* Not sure why they are selling this in the Apple apps store. It doe not work with IPhones. Don’t waste your money. I give 0 stars. Someone should take this app out of the App Store. ### 1/5 — Useless. Won’t connect to camera to work *2019-03-21, version 2.0* Like others, I am now getting a Permission Error, where it says I need to grant permission to access the camera in Settings, but then I go to Settings and it doesn’t give me that option ### 1/5 — Don’t buy *2019-02-11* Doesn’t work on iPhone X. Setup doesn’t see the app. ### 4/5 — Error message *2019-02-08, version 2.0* It shows an error message that requires access to the camera, but no permission can be given in the settings. ### 1/5 — Not working on iPhone XS *2018-12-16* Can’t turn on the camera permission. ### 1/5 — Doesn’t work *2018-12-14* This doesn’t work for iPhone X - no way to let the app have permission to access camera ### 1/5 — Does not work on iPhone XS and iPad Pro *2018-12-05* I loved this simple app for years. My recent update to new iPhones made this app useless. I am having same problem as others. Asking for camera access permission on launch and takes me to settings. There I do not see this app to hand the permission. I hope the developer fix the issue. ### 1/5 — Unusable *2018-11-25* I just downloaded it to my phone. I can’t give it permission to access the camera because it doesn’t show up in my settings. I’ve tried hard booting twice with no success. It won’t work without this permission, so I’m screwed. Waste of a dollar. ### 5/5 — GREAT APP!! *2016-10-21* Enjoying this app for it's simple manual-like operation and accuracy. ## Frequently asked questions about FotometerPro ### What does FotometerPro do?
