That is the best feature of this app. Rumor has it that Apple forced the developer to delete it. Why? Without the free up memory button this app is only a shadow of what it once was. Come on Apple, let the developer put it back. ### 5/5 — Assistant *2021-12-29, version 6.1* Very good assistant’s ### 5/5 — Desempenho *2021-02-07* Funciona perfeitamente ### 1/5 — Running in late mode *2020-05-26, version 6.1* Can’t get this utility to run in advanced mode.
