The phone is nearly 1 year old. The lack of support means that I am you able to sample our testing sites…. ### 1/5 — Teurer Müll *2024-02-15, version 3.8.0* Die Kamera von meinem iPhone 15 Pro funktioniert offensichtlich überhaupt nicht mit dieser App. Die Kamera wird sofort unscharf sobald man sich dem Testkärtchen nähert. Ich bin wirklich sehr enttäuscht, gerade weil das Produkt viel Geld kostet. Absolut keine weiterempfehlung!! ### 5/5 — Great Product *2023-05-09, version 3.6.8* I love the microbiometer but lately the app has been very slow, especially the camera when taking the picture. The app use to work wonderfully but this past month I have been experiencing issues. I have the app on multiple devices, and all the devices are experiencing the same camera/pic delay as well as inability to access previous sample data. I do hope there is an update to fix any issues, I love the info from these tests. Thanks ### 1/5 — Camera problems *2023-03-08, version 3.6.6* If you have an I phone 14 pro the app doesn’t work with the camera I try everything With the old iPhone 10 ore x it works ### 1/5 — In app camera can’t focus on the test *2022-10-06* There needs to be a the ability to sub tests for analysis from the photo library. The in app camera can’t use the iOS multi camera focus function for the close focus required for the test ## Frequently asked questions about microBIOMETER® Reader ### What is the microBIOMETER® Reader? microBIOMETER® Reader is a mobile application that works with a low-cost testing kit to provide on-site soil analysis.
