what if social media was just... talking? no cameras, no filters, no typing essays. just hit record and say what's on your mind. that's undeafen, a social network built entirely around voice. voice your thoughts. let the second thoughts go in the caption. rant about your day. spill the tea. share a hot take before you overthink it. post your raw, unfiltered thoughts the way you'd send a voice note to your best friend, except the whole world can hear you. add a caption if you want, reply to people in the comments. but voice always comes first. no photos. no videos. no performing. just expressing. anyone can show up and hit record. your profile pic? an avatar you build from scratch. because here, your voice is your identity. what you can do: - drop voice notes with optional captions - connect with your friends or discover new voices from around the world - follow people whose voice you vibe with - react, reply, and comment undeafen is for the things you feel but don't want to type. the stuff that sounds better out loud. built with safety and privacy at its core. your voice, your space. hear the world. be heard.

Some words are meant for a particular moment. Open When helps you write thoughtful letters to yourself and the people you care about. Choose the moment a letter belongs to, write what you want them to know, and send it to their mailbox. Make it available right away or seal it until a date you choose. WORDS FOR THE MOMENTS THAT MATTER Choose from meaningful prompts for good days, hard days, big dreams, quiet reminders, and everything in between. You can also create your own Open When moment. LETTERS WORTH KEEPING Connect with people using friend codes and exchange letters. Favorite the ones you treasure, or turn any opened letter into a keepsake PDF you can save, share, or print. You’ll also receive a notification when a new letter arrives or a sealed letter is ready to open.

Verdict
The clearest difference is in-app purchases: Undeafen at none against Open When's 1. Undeafen also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.0). Open When's advantage is update cadence (daily vs every 3 weeks). On price and ads there is nothing between them.
