    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.

    Is there to set or choose to dynamically clean ram?

    I purchased Device Monitor and its $1.99 Pro Plan for my iPhone and iPad Pro, especially for the RAM cleaner. I was hoping that cleaning the RAM would help speed up the iPad a bit because I use the iPad as a laptop replacement to write reports and do spreadsheets. (I have a Macbook laptop, but I prefer the iPad because it has a touchscreen, which the Macbook lacks. Someday, I hope that Apple will make touchscreen Macbook Airs). Both of these devices tend to run close to being out of RAM even with only a few apps open. As I write this, the usage of the iPad’s 16Gb of RAM is at 97%. After running deep RAM clean, it dropped to 84%. The other features are useful to monitor the system status. I know that RAM can be cleaned on startup but is there a way to get the Device Manager app to automatically clean or deep clean RAM dynamically as it is needed?

    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!!!
