How it works
One bottle. A shared story. Start with a thought and see where people take it.
Write your message
Share a question, memory, or wish. Add your name or stay anonymous. Your optional city marks where your bottle starts.
Cast your bottle
Choose its reply goal, up to 100 stops. Casting uses one penny; new participants receive 5 free starter pennies.
Share the link
Tap Share this bottle and send it through your preferred app. Reading and sharing are free.
Add a thought
Wipe the bottle to read it, then tap Add your penny. A saved reply uses one penny and joins the same story. Each participant can reply once per bottle.
Follow the journey
Find your story in My bottles or The journey. Select a reply in View all thoughts to read it. At its reply goal, the bottle comes home and remains readable and shareable.
A few helpful details
How do locations work?
Use your current city or optional GPS pin. A reply with a location adds a recorded stop; forwarding a link alone does not. To reach a particular city, share with someone there—Penny does not route bottles automatically.
How do I keep my pennies and bottles?
Return in the same browser, or save your private recovery key from the balance panel to restore your wallet on another device. Never share that key.
Can I edit a saved message?
Check your message before casting or replying. Saved messages cannot currently be edited or undone. Anyone with the bottle link can read its story, so keep personal details out.
