That couldn’t be how much memory is being in used. ### 3/5 — New version is buggy *2025-10-30, version 4.0.9* I have a new phone. This app has become a yearly subscription. When attempting to register my account, the @ is not permitted. Without it, the email is not valid. ### 2/5 — Why do we need an account now?? *2025-01-14, version 4.0.7* Now happy about this. Used this app for years. ### 3/5 — Sympa mais *2024-12-10, version 4.0.7* L’application est sympa mais comme souvent on est spamé de temps en temps pour passer à la version pro. Ras le bol ! ### 2/5 — Pretty *2024-10-10, version 4.0.4* Pretty, but that’s about it ### 2/5 — Subscription based, login required, privacy concerns *2024-05-27, version 4.0.4* UI looks great but it’s Subscription based, login required, and has privacy concerns with the amount of access needed. ### 1/5 — It’s a paid app *2024-02-22, version 4.0.3* They should of advertised that once you log in you have to pay immediately before using anything ### 1/5 — Used to be free *2024-02-19, version 4.0.3* Used it for a long time to see storage usage, opened today and it wants me to answer questions and sign up / monthly payments. Long press on app and confirm delete. ### 1/5 — This app has become an insult to users *2024-02-15, version 4.0.3* The application has become one of many others that asks for a subscription to show statistics that it has always shown, as well as asking to create an account without a justified reason. Should I sign up just to see how much RAM my phone has taken up? you are crazy. ### 1/5 — Disappointed *2024-01-16, version 4.0.3* Does not show what apps and/or processes are in use which makes the app basically useless! ### 1/5 — Gelöscht *2023-11-28* Für gelegentliche Nutzung jetzt bezahlen (Abbo). So umfangreich ist die App dann dochnicht. ### 1/5 — that price.. *2023-11-28, version 4.0.2* ..it’s a joke - right?!.? ### 1/5 — Nach dem Update *2023-11-25* Ist die App sehr abgespeckt worden. Vorher gab es mehr Informationen. ### 1/5 — Génial ! Non c’est loin d’être Génial ! *2023-11-23, version 4.0.1* J’ai payer cette app, il y a de cela quelque année et subitement par rapport a la dernière mise a jour ! il faut un compte pour éventuellement être dirigé vers un abonnement ! Ok je tien a faire savoir a tout les développeurs que tout les apps amenant ou obligeant les utilisateurs a s’abonné pour utilisé des apps qui ont était payer seront irrémédiablement viré a vitesse lumière de mes périphériques et si il y en n’a qui sont dans cette situation de procédé de la sort, faut arrêté de nous prendre pour des pigeo… bien a vous 😡 ## Most critical reviews (10 lowest-rated) ### 1/5 — era grátis *2026-07-29, version 4.0.9* era grátis agora agora não dá pra usar sem fazer uma conta ### 1/5 — iPhone 17 pro *2026-07-25* Despite payment the device is not updated to Pro version ### 1/5 — Cannot run it for free *2025-11-23, version 4.0.9* without an account. Jesus. ### 1/5 — Nur mit Abo nutzbar *2025-10-06* Sinnlos - geht nur mit einem Abo… nicht zu empfehlen !! ### 1/5 — Just Frosting no cake *2025-07-08, version 4.0.9* Graphical interface without useful purpose or functionality. A total waste of time and $ ### 1/5 — Now Requires Login Account *2024-12-03, version 4.0.7* I’ve been happily using this app for many years and I’ve always been happy with it. However, one of the recent updates now requires you to create a “login account” with Google, Apple, or with Tekton itself. There is NO reason to suddenly require me to “login” to use a free app for monitoring system activity. Shame on you, Tekton. I’ll be uninstalling this app and looking for an alternative that doesn’t require a “login”. ### 1/5 — Not free *2024-05-27, version 4.0.4* I downloaded this app thru AppAdvice, and it said “free”. So, this app that gets you free apps is supposed to be free for lifetime. However, this is not the case. So, I won’t be using this app. I could have downloaded this app any day. So, I’m a little frustrated that I downloaded only to use it with a payment plans. Had I actually received the app free (without a paid subscription, I would have used it and reviewed it as see fit. Why put this app in AppAdvise if there is no difference in me downloaded without the free tool? Not happy at all. ### 1/5 — Ugly UI *2024-05-26, version 4.0.4* And vastly inferior to apps that dpnt require a outrageous subscription. This is at most a 29 cent app. ### 1/5 — $1.99 + $7 a month? *2024-05-24, version 4.0.4* Unless you guys are gonna make me breakfast in the morning, I don’t see how you could possibly ask that much money. I just wasted $1.99. ### 1/5 — Kayıt olmak istemiyorum! *2024-05-08, version 4.0.4* 1 yıldız verdim ve siliyorum. ## Most praised reviews (10 highest-rated) ### 5/5 — Good *2025-03-28, version 4.0.8* Good ### 5/5 — This is an excellent app! *2024-12-13, version 4.0.7* I’d say this is not only a classically informative app in a technical sense, the latest version (as of 12/12/2024) actually makes it a “beautiful app” !!! … and it’s a real pleasure to use … Highly recommended! ### 5/5 — System monitoring *2024-11-29, version 4.0.7* Very up to day ### 5/5 — メモリ解放できなくなってる *2024-10-20, version 4.0.4* 無料版の最終ページのフレッシュマークをタップしたらメモリ解放からの、Apple基準でできなくなったていで その実、そのページでどこでも良いからタップすれば前のページへ戻る→それを合図に メモリ解放できていて 非常に重宝していたのに、夏前のアップデート後久しぶりにやるとできなくなってない？ 今回の隠しコマンドはどこにあるのか。誰かレビューで教えて。 開発者の方、期待してます。 ### 5/5 — جميل *2024-09-25, version 4.0.4* تطبيق رائع ### 5/5 — Efficace *2023-11-22, version 4.0* Application efficace précise complète ### 5/5 — Ottima *2023-02-04, version 3.15* Fa molto bene il suo lavoro ### 5/5 — Thank you creator for respecting privacy and not being stalker like most apps *2022-12-03, version 3.15* Awesome works great ### 5/5 — Works well *2021-10-15, version 3.12* Provides unique 3-D graphics. ### 5/5 — Problem in last update *2021-10-07, version 3.11* There is a problem in the last update. I can’t restore or buy to unlock app. It just hangs I was using it with no problems until the last update Hope this helps, John --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
