How to cancel Lux Meter Pros subscription ⁉️

User reviews

It is far from a good app

It is not suitable for testing emergency lights . First problem is that you cannot even reverse the camera so you can make a picture with the light which you are measuring ( how do you prove that the light is the one you are testing if you cannot place the phone on the illuminated surface?) .

Second, you cannot create an emergency lighting certificate ( which I hoped it was in the app) . A completion certificate.

No offence but the developer should work together with a competent professional to better understand the process of testing a light.

I was so enthusiastic about this and i have paid the yearly subscription of £25 which i honestly regret.

All the best

Response from developer

Thank you for taking the time to write this. You were right on both points, and I am sorry the app let you down after you had paid for a year. Since reading your review we have rebuilt that part of the app. The next version adds a camera switch: the front camera lets you lay the phone screen-up on the floor or surface being lit and measure the light actually reaching it, and the rear camera photographs the luminaire so the reading is tied to the fitting you tested. It also adds a full set of BS 5266-1 emergency lighting certificates: completion (full and small installation), periodic inspection and testing, site compliance for existing installations, a luminaire test schedule, an illuminance report built from the meter readings, a central battery service report and a remedial works report, all produced as PDFs you can email straight from the app. We are fine-tuning it now and it will be on the App Store on or before 25 September 2026. If you can give the update a try, I would value your view of it. If it still does not do what you need, we will support a full refund. Subscription payments are handled by Apple rather than by us, so the request goes through reportaproblem.apple.com, and we will back it. We build this app with working electricians and add what they ask for, so if there is anything else you need, email support@luxmeterpro.com and we will look at building it. Mathew, Lux Meter Pro
