A monitor App that EVERYONE should use

Finally an app that covers exactly what I was looking for without complicating anything. I am technically fluent but not a Pro and this app can be utilized by all. Easy to understand and track with several features. I appreciate that so much. I love the info provided for things such as what the acid test feature is. I enjoy the simple layout and reasonable price for all features. Several valuable tools are all in one app instead of scattered throughout individual ones. By far the best app I have found to monitor the performance and connections that is actually supported, up to date, plus without ANY data tracking. Give these devs $2 to support them back:) We all should be monitoring our devices! Btw I don’t often leave reviews like this but I applaud the Devs and thank you. I am curious about the capabilities of the NFC feature. I keep seeing this pop up on $ app connection at a place that has nothing to buy. There’s not an option settings to turn it off and I’m not comfortable with openly broadcasting the connection.

Cool app

Has been useful especially the ability to add “hey Siri, clear ram“ to my Shortcuts. I am surprised that Apple actually allowed this functionality to be included with a utility like this. Because they added all kinds of restrictions to the “Battery Life“ app by RGM to the point where it no longer gives any useful information at all. They also destroyed the “Cleaner One“ app by Trendnet, which used to be called “Dr. Cleaner“, that one used to allow you to clear your caches. The latest versions are pretty worthless.

But this app as it is has this one extremely useful RAM clearing function, and I use it at least two or three times for a day because it helps speed up my work.

It was worth the in app purchase.

This app is amazing! BUT I have ONE REQUEST

My favorite thing about this app is the clear ram memory function. This app does the best job of clearing ram compared all the other alternatives out there on the App Store for iOS operating system.

However, my biggest pet peeve with this clear RAM memory function is the checkmark screen---it shows how many megabytes of RAM it cleared after the clear memory function has been used. My problem is that I like to spam the clear memory function so I can reuse it to clear the most memory possible to make my phone extremely quick. However, with the checkmark screen taking so long to disappear after each time I use the clear memory function, It takes too long to actually clear all the memory I can clear on my phone

Request: can you shorten the checkmark screen to nearly nothing so that I can spam the clear memory function more often? that would be an amazing fix imho! I will change this to 5 stars when you fix this THANK YOU FOR YOUR CONSIDERATION DEVELOPER TEAM!!!
