This app is great for tech savvy people like me, and tells you all you need to know about the specs of your device. Despite this being the lite version, I haven’t found a need to buy the full version. But if you need to compare devices, the full app works good for that. But I think the full version should be a bit cheaper, maybe around 1 dollar instead of 2 or 3. I also think this app would be better if it had a built in benchmark test even if it was a full version only feature. Over all, this app does what it says. It’s not perfect, but it definitely shows potential I’m glad an app like this exists, because I like to know about the inside of my phone/tablet. Thanks for reading.
☹️Notifications don’t work
timmy0&7
I’ve tried your suggestions. It still does not work. the app must be running and in the front in order to see the notifications. This defeats the purpose of having notifications. I got the app so that it would warn me when my device was getting hot. But that will only work when actually running and in the front. I understand your explanation as to why this is a limitation of the operating system, but still, what’s the purpose of having features that has no value? I would suggest they should be removed. Too bad, it was a great idea.☹️=Previous review = The notifications don’t seem to work in the latest version unless the program is running and brought to the front. Even with the program running in the background, the notifications don’t come up until you switch to the program. I’ve tried this with the battery charge levels, but I assume the same problem will exist in the thermal warning indicators and storage notifications. I hope you can get these to work. It would be a really great thing. Thanks for all your great work.

Hello,Thanks for flagging this. What you're seeing comes down to how iOS handles background execution. Local notifications can only be delivered while the app process is running, and Apple places strict limits on what an app is allowed to do in the background. That part is out of our hands.We do use several techniques to keep the process alive for as long as possible, such as background transfers. One thing worth trying is enabling the metrics server: active data transfers give iOS more reasons to keep the app running, which can help notifications get through.So this is a platform restriction rather than a bug we can patch on our end. If the metrics server solves it for you, we'd be grateful if you considered updating your rating.Best regards,The Lirum Device Info 2 Team
Amazing
dalechen2513
I’ve been reading other reviews, saying how u can’t use most of the features, and how there’s not even a task manager. I personally think that the app is amazing as it is, since it provides so much info that stock iOS apps can’t provide. I understand that a task manager can be implemented since this is only an app from the Apple store, but it sure is a step in the right direction(perhaps giving Apple some ideas ;)). If u like monitoring ur phone like me, this is the perfect app. Great job!
Thank you

Thank you for taking the time to update this app after 2 years ! It means a lot to us who are using the paid version of the app to still see support. I do have a suggestion though, I believe iOS 15 now offers more battery info. You may want to check out if there are any features you can bring back.
Developer Response
Thanks for sticking with us through the quiet stretch. You're right that recent iOS releases expose more battery data than older versions did, and we're going through the current APIs to see which readings we can surface again and which new ones are worth adding. If there's a specific metric you'd like to see first (capacity estimate, cycle count, temperature), drop us a line and we'll take a closer look.Best regards,The Lirum Device Info 2 Team
This update brings Mac specs to Lirum and introduces two brand-new tools.
- Device Grid: a new tool that lays out the complete specifications of every Apple device in one easy-to-browse grid.
- Mac models are now part of the device database: look up any Mac's specs on iPhone, iPad, and Vision Pro, and the Mac version of Lirum now includes the full device database too.
- AI Assistant: a new on-device assistant that answers questions about your device — from looking up specifications to tips on how to fix problems. Everything runs locally on your device.
