Slow down and write a real letter. One page, no erasing, the sound of a typewriter. Think first, then type, then send it to someone who matters.
Foldwriter turns your iPhone into a little letter machine.
Choose your typewriter and write one sheet the slow way. Every key you press plays a real recorded typewriter. The carriage moves along. The bell rings near the end of the line. Make a mistake and you type over it, the way people used to.
Three machines, each with its own shape, keys and sound:
• Sunday, a rounded 1950s portable with soft pillow keys
• The Editor, a black 1920s desk machine with glass keys on levers
• Rosso, a red 1969 pop portable with square keys
On iPhone Duo, half-fold it and it becomes a real typewriter: paper above the fold, keys below. Open it wide and the whole machine spreads across the screen. Close it and the page comes out of the machine.
When the letter is done, pull the page and swap it for an envelope. Type a name, pick a stamp, and post it. Your letter goes out as a picture, a PDF, or a short video of it being typed, through Messages, Mail, or any app you like. The person you send it to doesn't need the app.
• Uneven ink, overstrikes, and a red ribbon for the urgent bits
• Not happy with a page? Throw it in the bin and feed in a fresh sheet
• Long-press a key for accents and the euro sign
• Five stamps and a dated postmark
• A letter box that keeps what you sent
• Works on every iPhone, and with a hardware keyboard
• English and Dutch
No account. No ads. No subscription. No tracking. Pay once, type forever.
