Context. Scanly is my own iOS app: it turns the phone into a document scanner. Free on the App Store since July 2026, in 22 languages, with a weekly and a yearly plan.

  • Scanly onboarding: what do you scan most, Documents picked
  • Scanly paywall: scan, sign and share in seconds, the yearly and the weekly plan
  • Scanly: PDF Tools, with Add a Document, the AI tools and the converters
  • Scanly: add a document by camera, from Photos or from Files
  • Scanly: My PDFs, a tenancy agreement, an invoice, lecture notes and a receipt
  • Scanly: a tenancy agreement, page 1 of 2, with Sign, Sort, Edit, Add Page and AI

Problem. A photo of a contract is not a document. It is crooked, lit from one side and saved as a picture, so the next step is always another app: to crop it, to read the text, to sign it, to merge it into one file.

  • Scissors

    Crop it

  • Lines of text

    Read the text

  • A signature

    Sign it

  • Two pages

    Merge into one file

Goal. One app that takes a page from the camera to a finished PDF someone else can open ✦

  • Scanly onboarding: edit PDFs in seconds, a scan line sweeping over an invoice
  • Scanly onboarding: convert anything to PDF, the converters popping up one by one
  • Scanly onboarding: shrink files, keep quality, 1.4 MB compressing to 342 KB

Scan anything. Edge detection and perspective correction turn a photo of a receipt, a contract, a note or an ID into a crisp page, and several pages into one document.

The tools that usually live elsewhere. Text through OCR, a signature drawn with a finger, and converting, merging, splitting and compressing PDFs, all in the same place as the scan.

  • Scanly: a signature drawn with a finger above the line
  • Scanly: the signature placed on the tenant's line of the agreement
  • Scanly: compressed, 413 KB down to 151 KB

Ask the document. An AI summary of what a document says, and answers to questions about it, so a long file does not have to be read end to end.

  • Scanly: the AI tools, Summarize, Translate and Ask
  • Scanly: a summary of the tenancy agreement with its key points
  • Scanly: asking the agreement whether you can move out early and keep a cat

Twelve days. From the first commit to the App Store, built with Claude Code. Day one already had the home, the converters, the AI tools and the onboarding quiz.

Shipped solo. Designed in Figma, built in SwiftUI with Claude Code, submitted to the App Store and instrumented with PostHog, all by me. The App Store page, its screenshots and their localisations into 22 languages are part of the same design work.
