Still work fine on my android phone. *2026-03-20, version 2.3.8* App doesn’t open on iPhone 14 anymore. Still work fine on my android phone. ### 1/5 — New update *2025-07-16, version 2.3.3* New update and the app won’t connect to devices anymore. Frustrating. ### 1/5 — Could be great, needs work *2022-06-28, version 1.5.12* App needs work, crashes on boot up and needs to be uninstalled to solve sometimes. Sometimes it won’t start for a week. Other times it starts right up like normal. Love the tools but this app may be the reason to switch to testo ### 4/5 — First time on new app *2020-07-17, version 1.4.7* I purchased the ion gauges last year. I tried them once and didn’t like the old app. I used this app today on a split system start up. I need to play with it more but I thought it was convenient. I would like to export my saved data in a pdf. Both times I’ve used the charging tee it didn’t come off the system easily( user error possibly). The core depressor just needed to be adjusted, it works very well now. The ability to export data is nice, I will be using this on my start ups now. ### 1/5 — Ridiculous *2019-12-08, version 1.3.2* Locks up, freezes, loses data, micron scaling is awful. Chart in general is awful. Your tools are amazing, what happened to the software guys? ### 1/5 — Good device Bad App *2019-08-30, version 1.2.5* This is a revised App from the original. The original app had lots of bugs but was way better. My favorite function that this one does not have was the trending rate. This app is very dissatisfying and can no longer recommend this device. ### 5/5 — Great products *2019-06-30* Great app for great products, keep up the awesome work. ## Frequently asked questions about Appion Central ### What is Appion Central?
