The Settings are uncrowded. There is comprehensive documentation. Thank you, sincerely. ### 5/5 — The free version is kinda of insane *2026-04-09, version 5.1.16* It’s a really solid app for anyone who wants to know more about their device or keep an eye on how it’s performing. Useful, well designed, and definitely worth having on hand… it combines all the tools I need: a better activity monitor kind of thing, a storage analyzer that combines what other 3-4 apps do (some paid, some free), but its good to see all of these features in one single app. I don’t even know what the paid version has ### 5/5 — Thank you *2026-04-07* Don’t know where to start when it comes to all the positives about this well made and aesthetically pleasing little app. The updated version beautiful and the functionality is smooth and user friendly. Absolutely try this app, it outshines all the other apps in its category,and has set new standard. ### 5/5 — I thought it was abandoned but it’s better than ever! *2026-03-30, version 5.1.15* I remember finding out about lirum back in 2018 when i was a nerdy middle schooler but now i’m in university and it’s better than ever, Thanks devs ### 5/5 — Best *2026-03-29, version 5.1.13* Best app i have used to know about my iPhone .. ### 4/5 — Jimmy *2026-03-23, version 5.1.13* All i ask is exact temperature measurements if it is possible dont know if there are exact thermal sensors in the iphone but would be amazing if that where added to the lite version ### 5/5 — Super app *2026-03-21, version 5.1.13* The app is such a great application to learn things about your own phone the app overall is fantastic it shows the usage of all the cores and most of the information about your phone that you can learn ### 5/5 — Fantastic app does everything possible *2026-03-13, version 5.1.13* I've used dozens of system status apps and this is the best one for hardware information I've seen. Ppl you all need to recognize that in iOS 10, Apple REMOVED, DELETED the ability for apps to access much of the battery data that was available on iOS 9 and earlier. In iOS 11 Apple removed 3 of the 4 things left. Now in iOS 12, Apple has left ALL developers with nothing more than the current battery charge. This is an unavoidable fact. ALL BATTERY APPS WILL HAVE THIS SAME PROBLEM ON IOS 12! BLAME APPLE because they're the ones who removed it. There is literally NOTHING any app developer can do to make the app get that old information on iOS 12. However you can use the amazing free Mac and PC software "3uTools" and it will show you EVERYTHING about your battery, twice as much as any app ever showed on any iOS!! Trust me you'll be astonished!!! I think it's 3uTools.com ## Frequently asked questions about Lirum Device Info 2 ### What does Lirum Device Info 2 do?
