PenPal

/ˈpɛn pal/

(n): a friend whom you communicate with by exchanging letters.

Most apps are built to keep you scrolling. Lettre is built for the opposite: taking your time. Every letter is a page, not a message bubble, so make it yours. Write it by hand on iPad or type it on iPhone, color it, add stickers or bring in your own art. Then seal it, stamp it and wing it over to Pippin, who'll carry it the slow, old-fashioned way to a friend. Any friend, whether it's someone from your real life who doesn't have the app yet, or a PenPal you have yet to meet.

Two ways to say hello

A message

  • Typed in seconds
  • Seen, then scrolled past
  • Lost in the feed

A letter

  • Written over an evening
  • Carried at pigeon pace
  • Kept, treasured, answered

App Store reviewApr 25, 2026

My new favorite app

In an algorithm dominated world, this app feels so much slower and human. It’s not follower based so you can actually connect with real people all across the world. And the best part is that it’s completely free with no ads and NO GENERATIVE AI. I’ve only had this app for a few days and I can confidently say I love it and I cannot recommend it enough!

Will the recipient get a tangible, real-life letter?

Not yet!

For now, all letters sent through Lettre are digital. But we're working toward making physical mail possible in the future.

Maybe sooner than expected. Shh.

How does one go about writing letters?

We strongly recommend having basic reading and writing skills for the best Lettre experience. As for the letters themselves, they can be as creative, silly, heartfelt, or formal as you'd like.

There are no set rules here. Have fun and express yourself however you want and however you can. This isn't some boring old text box. You have a canvas with practically limitless potential!

How do I post my letters? What's the process?

Once you've finished writing your letter, you'll see an envelope / paper-plane button in the top-right corner. Tap it to continue to the envelope screen.

From there, you can:

  1. Choose your recipient
  2. Customize your envelope
  3. Add the required postage
  4. Hit Send

And don't worry. Our competent postal-bird, Pippin, will take it from there and make sure your letter reaches its intended recipient, wherever they may be.

Can I send letters to people who don't have the app?

Absolutely!

As long as you have their contact information or email address, you can send them a letter. They'll receive a copy by email along with instructions for downloading Lettre and getting started.

The letter can also be saved directly from the email as a PDF or image, including the envelope.

What if the recipient doesn't have the app or an iPad?

Fear not! Your letter can still reach them.

They won't have access to the full Lettre experience or be able to collect stamps through the app, but they can receive your letter through email or iMessage.

As of now, you can send letters to:

  1. People on Lettre whom you've already added to your Address Book
  2. The PenPal Stack, where people can discover your letter and hopefully start a conversation with you
  3. Anyone whose email address you know
What should the recipient do next?

Simply download Lettre and sign up using the same email address where they received the invitation.

And voila! They're ready to enter the world of letters.

Can I unsend a letter or recall something I've sent?

We believe in thoughtful communication, so being able to take back a letter is intentionally limited. But we also believe in second chances.

For private Mailbox letters, the ability to unsend a letter is one of the exclusive superpowers available to Pippin Supporters Club members. It also helps us keep spam and unwanted messages at bay while giving our supporters an extra bit of value for helping keep Lettre running.

For PenPal letters, you don't need to be a Supporters Club member to manage them. Visit your PenPal profile to see the letters you've posted. From there, you can pause, resume, or delete them whenever you'd like.
