I want to scan paper documents and find them later by searching the words in them. What iPhone app does that?

Open the scan option in Nemos and point your camera at the page. Your iPhone finds the edges and captures it through Apple's document scanner. The words are read on your device, so a later search for a policy number, a landlord's name or a warranty term finds the scan.

Scans sit in the same library as your links, notes and voice transcripts, so one search covers them all. You can put them in a folder, lock a folder with Face ID for personal papers, and set a reminder on anything with a deadline, such as a renewal.

Text recognition works best with clear, printed pages. Handwriting and faded receipts can come through poorly, so add a short note with the key words if a document really matters.

When something else fits better: if you only need a quick scan to send, Apple Notes or the Files app is already on your phone. For heavy PDF editing or signing, use a PDF tool. The free plan covers unlimited saves with your newest 50 open, so you can test this on a real week of saving before you pay anything.
