Roomier vs your phone's built-in cleanup
Your phone already does some of this, and it's reasonable to ask why you'd install anything. Here is the honest version — including the cases where you shouldn't bother.
What the built-in tools actually do
iOS has a Duplicates album that finds identical files and offers to merge them, a Screenshots album, and a storage screen that tells you how many gigabytes Photos is using. Android has much the same through Files by Google and the Google Photos storage manager, which also flags blurry shots and large videos — for the library you've backed up to Google.
All of that is real and all of it is free. The gap is that “duplicate” on iOS means the same file twice, while the thing eating your storage is usually the same moment shot eight times — a burst, a retake, a photo and its edit. Those are different files, so they never appear.

When you don't need Roomier
If your library is under a couple of thousand photos, the iOS Duplicates album will probably clear what little there is to clear. If you already pay for enough iCloud or Google storage and space simply isn't a problem, tidying is an aesthetic preference, not a need. And if you back everything up to Google Photos anyway, its storage manager covers blurry shots and large videos without another app.
Roomier earns its place when the library is large, mostly camera roll, and full of near-misses that nothing else can see — and when you'd rather not upload it anywhere to sort that out.
