Bottler

Bottler reimagines social discovery as a message in a bottle. Instead of browsing profiles and swiping, you compose a short note, attach a handful of tags, and cast it out. The app's matching algorithm then decides who should receive it based on the tags you chose, how active those users are, and how likely they are to reply. If nobody picks your bottle up in time, it keeps drifting and is guaranteed to reach someone within roughly a week.

Once a bottle is caught, the app opens a chat so the two of you can keep talking. A dedicated reactions feature lets people respond without writing a word, and you can pass a bottle along if it is not for you. Over time you can build a friends list, follow people, and use the tags to look for partners, penpals, or even job leads depending on the tag categories you pick.

The paid tier, Bottler Plus, raises the sending limit to around ten bottles a day, allows up to ten tags per bottle, and unlocks features such as attaching a song from Apple Music so whoever finds your message can listen to it. Bottler is available as a free app with in-app purchases on the App Store, rated 13+, and supports both iPhone and iPad layouts.
