Editors’ Notes

All-in-one hardware diagnostics for your brand-new phone.

Amazing App!!! A Must Have


Love this app! I’ve never found an app that does everything this app does. It works perfectly and does everything exactly like it says it does. Great app to have and to use if you are selling or buying a phone or even just to check your own phones functions and hardware. A must have app to have. The only thing I’d like to have other than what it has already is a Battery Check and iCloud Unlock.

Great Diagnostic App


This app is great for testing your phones functionality. All the tests works great except for a glitch I found on the 3D Touch test. I’m unable to get a response pressing down on the areas it asks when the setting is set for firm on my iPhone X. The test tells me it failed. Works fine on light and medium settings. Possibly a glitch as I don’t have any issues on firm for 3D Touch on any apps I’ve used.

Add a battery test too and I think the entire phone is covered.

Thank you for the review and the feedback! We will look into it :)
