Spreadsheet in. App out.

Your spreadsheet is already an app.

Rapp turns the sheets your team already runs on into fast, polished mobile apps — live-synced, secure and ready to share. No code, no rebuild.

Start with the sheet you have.

Point Rapp at a spreadsheet you already use — rows, columns, formulas and all. Nothing to export, nothing to tidy up first.

Every column is read and typed: people, dates, money, statuses. Totals and relationships are found for you.TextPersonStatusDateMoney

Records turn into cards, numbers into charts and headers into navigation. A native-feeling app takes shape in seconds.

Share a link or publish to iOS and Android. Edits made on the phone write straight back to the sheet, so both stay in step.

Features

Rapp keeps the spreadsheet as the source of truth and gives everyone else an app they actually enjoy using.

Live two-way sync
Change a cell and the app updates. Submit a form on a phone and a new row appears in the sheet.
Fields that know their type
Dates get pickers, money gets formatting, people get avatars and statuses get colour — automatically.
Roles and row-level access
Decide who sees which rows, who can edit them and who only reads. Rules travel with the data.
Works without signal
Capture jobs, photos and signatures in the field. Everything syncs the moment you're back online.
Charts from your formulas
Totals, trends and progress are drawn straight from the sheet, so the numbers always match.
Yours, not ours
Your name, colours and icon on every screen. Share a link, or ship it to iOS and Android.

Built for the people who already run the business in a spreadsheet — and everyone who has to work from it.
