On Android, full RAM usage is not necessarily a problem. We'd thus recommend the original version for reliability until the newer one replaces it. While it has a more modern look than the original, the developer notes that this app is still early in development. Note that at the time of writing, SD Maid 2 is also available. Take a look at what's on offer to see if upgrading to the Pro version is worth it for your needs. There are also tools for storage analysis (to help you find and delete big files) and mass app removal if you're considering a bigger phone tune-up. In our test, it cleared 40MB from Spotify this way. There's also a Databases area to help optimize any app databases in use. To use this feature, however, you'll need to upgrade SD Maid Pro. If you like the sound of this, AppCleaner performs the same action for your apps. SystemCleaner is another search-and-delete tool, this time looking for common files and folders that SD Maid believes it can safely delete.
The first, CorpseFinder, searches for and erases any orphaned files or folders left over from deleting an app.
