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.
Good but broken on some devices

As the title says, this app is great for checking all the specs of your device and it helped me greatly while testing out how much RAM a beta game was using. Only problem is that this app only works on my iPhone XR but fails to even open on my iPad Pro 11”. The app just crashes when opening it. For now I’ve switched to something else but please fix this.
Amazing

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!
EULA MODIFICATIONS REQUIRED
Jon&Alicia
Section 4 (user responsibilities) of the End User License Agreement is woefully in need of revision. A lawyer advised me not to accept the EULA as written because of section 4."You agree not to use (or rely on) the App for safety-critical, emergency, medical, legal, financial, or other high-risk decisions or use cases where errors could lead to harm, loss, or liability."Change it to something like:"User acknowledges that this app is not a substitute for professional persons when undertaking high-risk decisions, including, but not limited to safety-critical situations, emergency, legal and financial options. User further acknowledges the developer is not responsible for any unfortunate outcome(s) of relying upon this AI's advice."
This update adds faster navigation, broader diagnostics, and clearer guidance.
- Find tools faster with the new tool search.
- Follow a manual hardware test checklist for more structured device checks.
- Optionally share benchmark results anonymously to improve device performance comparisons.
- Explore new network tools and expanded diagnostics.
- Updated documentation and general usability improvements.
