About as basic as you can get. Nice features to add include a description of what to expect for performance and a battery temp monitor and capacity stored along with stats. It's no unusual for the CPU speed to dial back with temp and battery life.

Sorry, but this app is totally useless on my phone with iOS 11.2. Not sure if the developer hasn’t updated it to correctly work with this version, but will not even start up. Too bad, because it would be a handy app... maybe another out there... I would even pay for it if it worked..

Just didn’t work at all. After starting the app I get a screen with a gauge and 10 seconds later the app crashes. Tried closing apps and rebooting my phone but no luck. Waste of time.

The description as of 12/29/2017 indicates that for a limited time if you rate this app, ads will be eliminated for free. NOT TRUE!! After downloading this app (and being besieged by full-page ads), I rated the app. Ads weren't removed. Bye, bye. This app is headed for the bit bucket. Replacing with GeekBench 4 (which is what I should have gotten in the first place…)

This app crashes with iOS 11.2.1. Apparently Apple doesn’t want us to know or find out how severe their throttle back program is!

The description of this app when I downloaded it, and still, offers free upgrade to ad-free if you rate the app. I did so (via the app) but ads remain. Restarting the app and my phone didn't change anything. Decided to in-app purchase the upgrade. Failed repeatedly due to "unknown product identifier." Went to their website – no products featured, described or supported. Argh. Is this abandonware? Goodbye five-star review. [Previous review deleted]

The “speedometer” shows upon opening. Nothing else: no branding, title, tools or hints. Really, the picture isn’t even that pretty..
