USOM Mail on iPhone

The same receiving-only mail as the browser version, in a native app. Carry manual pull-to-refresh, color themes and shared viewing with you.

Coming soon on the App Store

Distribution has not started yet. Until it launches, the browser version works as-is (the account is the same).

What the app can do

  • Disposable addresses on the spotYou can issue a receiving-only address the moment you need one. Even on the free plan you can hold up to 5, so you never have to hesitate before creating another — and when you're done with one, deleting it closes the loop.
  • Set your own expiry timeYou choose anywhere from 1 to 60 minutes for how long an address stays alive before it disappears on its own. Set it short for a form or a one-time signup, and you won't have to think about it lingering afterward.
  • Manual pull to refreshThe inbox loads the moment you open it, and pulling the list down brings you the latest whenever you want it. Switch to an address you're viewing through shared viewing and that inbox refreshes the same way.
  • Automatic background checkEven with the app closed, it checks for new mail roughly every 30 minutes in the background, so you don't have to keep opening it just to look. A notification lets you know only when the count actually goes up — and since it never fetches the message content, nothing leaves the server until you open it yourself.
  • Five color themesPick whichever of Standard, Midnight, Honky-tonk, Forest or Sakura matches your mood. It's saved per device, so once you choose, it stays that way — and USOM changes color right along with you.
  • Shared viewingHand someone a QR code or a link, and they can look through your inbox read-only from then on. They can't delete or reply, so you can share it with family or a team without worrying about what might change.
  • Stay anonymous / link GoogleYou can start using it right away with no sign-in. Link a Google account and the same inbox follows you across devices and browsers — and because the address you sign in with is kept separate from your disposable ones, the two never get mixed up.
  • Clear about how things disappearMail you've received clears itself out once it passes the retention period (30 days on the free plan), so you don't have to tidy it up yourself. Delete your account and you still have a 30-day grace window — sign back in with the same Google account before it's up, and it's as if nothing happened.

More native features

  • Persona data, kept on the deviceYou can generate fictional Japanese names, addresses, birth dates and more without anything leaving your device. Not happy with the result? Regenerate it. You can copy individual fields, jot down a note, and even attach an Image Playground portrait — and because it's all stored as device-only JSON, there's less to worry about.
  • Action button, Siri, Spotlight and QRCall the Action button, Siri or Spotlight and an address is issued without you ever opening the app. It comes back as a snippet with a QR code already on it, ready to hand to someone as-is.
  • A fuller inbox workflowSwipe through a carousel to switch addresses, and expiry and message-count badges tell you where things stand at a glance. Delete what you no longer use, page through a big inbox instead of scrolling forever, and watch mail group itself by date while the header tucks away as you scroll — the more you use it, the more it gets out of your way. Pick your display language from 11 options, too.
  • Per-address alias, notes and QR messageYou can give a disposable address its own device-only display name and note. The QR screen is built with the other person in mind, so you can write it a clever custom message before you show it — and setting its sheet to close only via the close button means it won't vanish mid-handoff.
  • See received-mail counts per contactA display name and note mean you'll always remember who you handed an address to, and its received-mail count is right there alongside it — so looking back, you can tell exactly how much a given contact or service has actually sent you.
  • Privacy-minded even when swapping addresses one-on-one, a lotThe moment your QR code is on screen, the address list behind it blurs out of view on its own. Set the sheet to close only via its button, and even if someone snaps a photo right then, none of your other addresses end up in it.

Screens

Browser version vs. app

  • Browser versionNo sign-in, right now. Works on a PC too. Leaves few traces even on a shared PC.
  • App versionFor people who check often on the go. Manual refresh, themes and shared viewing are all in one place.

Launch announcement

Once the launch date is set, we will announce it here and in the FAQ. There is no plan yet for an Android version.
