Wen, live
Wen is a personal finance app for iPhone and iPad. Give it what you’ve saved, what goes in each month and the down payment, and it tells you the month you can close on a home.
The phone is running Wen’s close-month engine. Drag anything in it. The shipping app goes further: taxes in each state, rent against buy, and five metros at once.
40 months. $60,000 to go.
Another $500 a month closes 10 months sooner.

Close. The month you can buy. Life. What else is on the plan. Widget. On the home screen.
CloseEvery app, made here
Four stages, the same for every app on the mountain, from the first sketch to the support email that comes in a year after launch. Open one.
Design
Every screen, colour and icon is drawn here. Wen’s sky, its ridge and the tent pitched in front of the sun started on this desk.
Build
Wen began as a spreadsheet. Its engine is a port of that workbook, held to it by tests that agree within a dollar.

Ship
Before an app goes to the App Store, its support page, privacy policy and terms are up on this site, where Apple looks for them.
Run
Once it ships, we keep it running. A support email is answered by a person who works on the app.

One seller,
every app
The App Store lists one seller for every app we make: 0xDevelopment LLC. This site is where that name and each app meet. The support page, the privacy policy and the terms for every one of them live here, at addresses that never move.
