Stellar Post
Social Networking
Only for iPhone
Free
iPhone
Write letters that travel across planets. Choose a stellar address, pick a stamp, and wait for the mail to arrive.
Stellar Post is a quieter place to write.
Instead of instant chat, you send letters. Claim a stellar address among the planets, choose a stamp, and wait for mail to cross the distance between stars.
Your address among the stars
Choose a planetary address. Your mailbox ID lets others add you as a pen pal.
Letters with time
Mail doesn’t arrive the second you tap send. It travels. Opening the inbox feels closer to real correspondence than another notification.
Stamps & pen pals
Choose a stamp before you send. Add pen pals with a mailbox ID, and keep a thread of letters that take their time.
You can also publish an open letter to Discover after a light review—optional, alongside private pen-pal mail.
