Ngumba
Scan, invoice, sign, keep
Free · Designed for iPad. Not verified for macOS.
Scan a document, send an invoice, sign a contract — free, and without an account. Everything stays on your phone.
Ngumba does the things people go to a business centre for.
Scan a page with your phone and get a clean, straight document — not a
photograph of paper. Make it small enough for a portal that keeps rejecting it.
Write an invoice and send it in under a minute. Sign a contract without
printing it. Put several documents into one PDF for an application.
Everything you make is kept, named, and searchable by what the pages actually
said — so the second time somebody asks for your documents, it costs nothing.
There is no account. There is no sign-up, no email to confirm, no subscription,
and no free trial that ends. Open it and it works.
Your documents stay on your phone. Not "encrypted in the cloud" — there are no
servers. When you send something it goes wherever you sent it, the same way a
photograph does. Turn on flight mode and everything except sending still works.
WHAT IT DOES
• Scan — a page, a receipt, a passport. Straightened, cleaned, readable.
• Fix — make a document small enough to send. Combine several into one. Take
pages out.
• Invoice — quotes, invoices and receipts, with your logo, your terms and your
tax. One document that renames itself as the work moves.
• Owed — who has not paid you, and what is late.
• Sign — draw your signature once, then put it on anything.
• Keep — everything filed by itself, searchable, and warned about before it
expires.
Free for the everyday things, because the tools already exist and are simply
not in most people's hands.
