## What is crossin?

Not a notification. A journey.
Some moments deserve more than a quick tap. crossin turns them into postcards you can send to someone you care about.
Choose where the moment begins, make your postcard, and send it to a friend—on crossin or off. A little pigeon carries it along a real route, from your location to theirs. It takes its time. It passes through cities, gathers stamps&crossmarks, then lands in a mailbox that belongs to the two of you.
One moment. Two people. A small journey in between.

## Key features

- Send digital postcards
- Use personal photos (live photos supported)

### 4/5 — Nice but needs improvement

*2026-07-03*

I love this app, its like seeing postcards from around the world! But it needs a lot of improvements: 1. Needs to have accurate locations of places. I couldn’t even find all the places I’ve been to in this app, and a couple of times couldn’t change location to where I’m at
2. Could make post dates and pictures taken dates (stamp) different so we can accurately post dates of past travels
3. The scroll could be a little smoother?

### 3/5 — Can’t delete a post card

*2026-06-18, version 1.6*

The app is good but if you post a post card then you can’t delete it. Being able to delete something you post is an expected feature to have in place in many apps.
It would be good to get that feature in

### 5/5 — I am just so happy 🐌📮💐

*2026-06-16*

this app is absolutely just a gem, everything about it is just perfect. another wonderful app to reflect myself, I hope to see more with this developer <3

### 5/5 — Suggestion: Feature to Add Friends within the app

*2026-05-27*

Hi!! I love your app! I live abroad and my bestfriends and I would always send postcards to each other whenever we visit new places. Maybe you can add a feature where you can add friends within the app that would be really cool! Then we have a stack of all our postcards sent to each other!

### 4/5 — Amazing app! Hoping for more

*2026-05-18*

This is such a fun app. I really do hope it keeps its simplicity. Like others I wish there was a way to change the location and date of the posts; also a method to add past travels and finally a way to follow people!!

### 4/5 — Excited to see it grow

*2026-05-04*

I’ve really enjoyed using Crossin as someone who sends a lot of physical mail. It’s a creative and fun twist on traditional social media, and has a lot of potential for people who love mail and travel culture.

I’d love to see a few key improvements. A way to browse postcards by region or map would make exploring much more interesting, (would love to see who’s local to me!) and a favorite option is needed since there’s currently no way to revisit postcards within the app once they’re gone.

A friends or following feature would also be great, especially with the ability to send postcards directly between friends, or specific postcards that are visible to friends only instead of everything being random or  public. There is a “pen pal” messaging feature, but a friends or following system would make more sense overall. At minimum, a dedicated space to post that you’re looking for pen pals would help, since most people aren’t randomly messaging each other directly.

More customization would make a big difference too, including choosing stamps for postcards and having more flexible layouts for longer messages. It would also help to be able to backdate posts when needed.

Overall, I love the concept and hope to see more community, collecting, and customization features added in the future! Excited to see Crossin grow 😊

### 3/5 — Loved it until...

*2026-04-21*

I was a huge fan until I discovered my Taiwan posts were being labeled as "Taiwan, China" with a China flag on my passport. Surprised that a group of young developers would not recognize that. I want to keep supporting them and help this app grow but that crosses the line for me.

### 5/5 — SO COOL

*2026-04-16*

I just downloaded and love this app so far!  My only wish would be that I could edit the dates of my postcards.  I have a recent trip that I’d like to add, but it was before I got the app.  Maybe there is a way to do this, but I couldn’t find it.  Great app otherwise!!

### 5/5 — Such a cute app!

*2026-04-10, version 1.5*

Love the design and the whole experiences!

### 5/5 — Such a fun idea

*2026-04-09*

This is a cool way to document my travel memories as postcards. I also love that I can send them directly to friends through messages while I’m traveling.

## Version history (last 5 releases)

### 2.0.1 — 2026-10-01

Replace store image

### 2.0 — 2026-09-30

Crossin 2.0 is here. And yes, we hired a pigeon!!
For the weird little sign. The ridiculously good sunset. The café you’d definitely drag your friend into.
Turn one of those moments into a postcard, pick a location, and let our pigeon take it to the person who came to mind.
Good things take a little flight.
Your postcard travels a real route. Follow your pigeon’s adventures and collect crossmarks along the way. A little anticipation is part of the fun.
They don’t have Crossin? Send it anyway.
Your pigeon will get the postcard to them, even without the app. Very committed to the job.
A little mailbox. Just for you two.
Once delivered, your postcard lands in your shared mailbox. A growing collection of “wish you were here” and “you would’ve loved this.”
You don’t always need a big life update to reach out. Sometimes, “saw this, thought of you” is enough.
