Free is no better than on board review. Cleaning is the game and its all PAY PAY ### 2/5 — Please fix the color of the app *2026-07-15, version 26.6.1* There are so many apps that are white. I keep looking for the black app with the green details. Doesn’t matter what I choose in the settings, it stays white. Please fix it and I’ll delete this review. Otherwise you’re golden. This has be the most frustrating design change ever. I get it, you want to make something new and fresh - but let people choose legacy design. It was one of the most unique standout apps for its display. Now I literally can’t stand it. ### 4/5 — Not really sure I didn’t do anything to my phone *2026-07-10, version 26.6.1* Cool all layout though looking for something to change my WebKit (no st) let me know ### 4/5 — need atuto RAM cleaning without PiP *2026-07-02, version 26.6.0* Hey developers please make the auto cleaning possible without needing to have picture and picture active cause i want to watch yputube on pip at the same time rune auto cleaning of ram in the background hope i see it in the next update thanks👍✌️ ### 5/5 — Peak *2026-06-22, version 26.5.0* The best ### 5/5 — Nice app *2026-06-12, version 26.5.0* The widgets help but sometimes takes it awhile to appear after changing wallpaper ### 5/5 — Best of it’s kind *2026-06-11, version 26.5.0* Absolutely the most comprehensive app of its kind. The ram cleaner does make a noticeable difference. When my phone starts running slow and glitchy I run a deep clean and it starts running smooth again without having to shut the phone down completely. Very well thought out and developed app. ### 5/5 — Nice *2026-06-11, version 26.5.0* I can do a lot of things clean my ram is the best one ### 5/5 — Latest PIP Update *2026-06-11, version 26.5.0* Hello, First, I want to thank you for developing Device Monitor². One of the main reasons I use the app is the RAM monitoring and automatic cleaning functionality. Before the recent update, I used the Live Activity RAM monitor with the auto-clean threshold set to 90%. I would activate the Live Activity and leave the app running in the background. This worked extremely well because it allowed me to monitor and automatically clean RAM while still using other iOS features, including Picture-in-Picture video. After the recent update, I noticed that the Live Activity option was removed and replaced with a Picture-in-Picture mode. While I can see some advantages to the new implementation, it created a problem for my workflow. Because iOS only allows one active Picture-in-Picture session at a time, I can no longer use Device Monitor’s RAM monitoring and YouTube (or other video) Picture-in-Picture simultaneously. My feedback is not that the new Picture-in-Picture feature should be removed. In fact, I think it is a useful addition. My suggestion is to consider offering both options: * Live Activity mode * Picture-in-Picture mode This would allow users to choose the implementation that best fits their needs. Users like me who rely on video Picture-in-Picture could continue using the Live Activity version, while others could take advantage of the new Picture-in-Picture monitoring mode. I really appreciated the uniqueness of the Live Activity RAM monitor, especially its Dynamic Island integration, and I hope you might consider bringing it back as an optional feature alongside the new Picture-in-Picture implementation. Thank you for your time and for continuing to improve the app. Best regards, A Device Monitor² User ### 5/5 — Simple, easy *2026-06-11, version 26.5.0* One time payment, simple easy interface, well designed, everything properly explained. Stellar app 10/10 ### 5/5 — Excellent *2026-06-10, version 26.5.0* The developer is very responsive and Device Monitor is worth the price. PiP 😁 ### 5/5 — A remarkably good technical app! ✅ *2026-06-07, version 26.1.0* This is one of the best device status tech apps I’ve seen and I’ve tested over 100. The king remains System Status by Jiri Techet but this one shows a lot more detail and has way more features. ### 5/5 — Good *2026-05-27, version 26.1.0* Great no issues ### 5/5 — Must purchase pro features functionality! *2026-05-27, version 26.1.0* Must purchase pro features functionality! ### 5/5 — 唯一の *2026-05-21* 使いやすいししっかり機能してる。ショートカットで使えるのは最高 ## Most critical reviews (10 lowest-rated) ### 1/5 — ***RANDOMLY SHUTS ITSELF DOWN*** *2026-08-02, version 26.6.1* The app will not remain active in the background. It randomly shuts itself down and has to be restarted. There are better apps out there, chose something more reliable! ### 1/5 — PIP *2026-07-04, version 26.6.0* This is terrible for use of Automatic Cleaning. Live Activities was a better option. ### 1/5 — SCAM! *2026-06-27, version 26.6.0* I checked my storage before clearing RAM in my settings, then I checked afterwards, and it did nothing, DO NOT DOWNLOAD THIS APP AS IT IS MADE BY SCAMMERS! ### 1/5 — Nooo *2026-05-31, version 26.1.0* I use this app and after I do I go on Roblox and it kicks me from whatever server im in ### 1/5 — Consome Muita RAM *2026-04-25* Aumentou em 15% o consumo de RAM no meu iPad A16. Muito pra um app que deveria otimizar. ### 1/5 — false *2026-03-14, version 26.1.0* scam ### 1/5 — Ios 26.3 *2026-02-05* Not working on iOS 26.3 ### 1/5 — Malo *2026-02-04, version 26.1.0* Se paga para engañar no funciona se tiene que pagar para todo el que creo esta app es un singa su madre ### 1/5 — Guys dont get this app *2026-01-31, version 26.1.0* Your device automatically cleans its ram and if it’s full thats because it needs to be. If you clear a bunch of necessary systems it will probably make the device slower, it’s useless in terms of ram management ### 1/5 — ***RANDOMLY SHUTS ITSELF DOWN*** *2025-12-29, version 26.1.0* The app will not remain active in the background. It randomly shuts itself down and has to be restarted. There are better apps out there, chose something more reliable! ## Most praised reviews (10 highest-rated) ### 5/5 — Cool *2026-07-15, version 26.6.1* Best ### 5/5 — Great informative app *2026-07-11, version 26.6.1* We need more informations ℹ️ on the device realtime temperature 🤒 it’s confusing when I open the link 🔗 And more realtime information ℹ️ on the ram usage with accuracy ### 5/5 — Excellent *2026-07-11, version 26.6.1* Would it be possible to have the option for dynamic island live activities and pip when it comes to monitors? Edit, sorry dev, Apple can really be ridiculous with all these restrictions stifling any kind of innovation. ☹️ ### 5/5 — Rare Find *2026-07-10, version 26.6.1* I have a new iPad Air M4 but still enjoy my old 8th Gen regular iPad. It doesn’t want to give up; so, it gets equal time. That being said, this old 8th Gen iPad has a first generation bionic chip (still a cool name) and just the standard 3 GB of DDR. The last few updates are making the old iPad show its age. There used to be plenty of apps to free up RAM but not so much anymore. This program does a deep RAM clean that snaps my old iPad back to where it can handle the new IOSs and continue for a multiple application session workout. Your program will be fun to run on the M4 Air with 12GB RAM! Thanks. ### 5/5 — This is a good app *2026-07-05* Very nice very nice beta good app u made ### 5/5 — app doesn’t lie *2026-07-04, version 26.6.0* This app does what it says it does, it tells my phones temp( low, mod, high), it shows how much ram im using, storage, cpu etc etc. overall im impressed with this app. Recommend it. ### 5/5 — Money *2026-07-04, version 26.6.0* Why do you have to pay for a better gaming experience ### 5/5 — Good *2026-06-30, version 26.6.0* Good things for looking at things on phone and about phone it's good for that and other things like tempurature of phone and RAM and GPU and CPU and stuff so I like it ### 5/5 — Best thing ever! *2026-06-27, version 26.6.0* This app actually works!!! ### 5/5 — Display the actual temperature *2026-06-23, version 26.6.0* I really like this app still, right? I would love for the temperature to be actually displayed (like say 88°F), instead of it saying "moderate temperature," "normal," or "high." Display the actual temperature, thank you. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
