Before photographs. Before film. There was voice. Taeppl is a cassette recorder for real moments — the ones you don't stage, don't edit, don't perfect. Choose how much room your tape holds, then record in bursts across a trip, a day, an occasion. Stop and resume whenever something's happening. When the tape's full, it's full. Keep the dog barks, awkward pauses, and everything in between. Each tape becomes a memory you can return to. Every tape ages. Wow, flutter, and hiss deepen as a tape gets older. Each tape has its own character, with a sound that gradually warms and wears while the original recording is preserved. Touch the reels. Drag to scratch playback in real time. Press and hold to freeze the tape mid-motion. Play with the sound as you listen. Link Tapes. Send a tape back and forth with someone you care about. Add your voice to the same growing recording, one turn at a time. Group Tapes. Build a shared memory with friends. Claim a turn, listen, add your part, and pass it on. A finished tape holds everyone's voices together. Birthday Tapes. Collect spoken messages from the people who matter and bring them together in a birthday gift. Arc Tapes. Set a future reveal date — a birthday, a milestone, a someday. Record over time and create something to return to when that day arrives. A map of memories. With location permission, see where your recordings happened. Choose whether shared tapes include precise locations, approximate locations, or no location at all. Handwritten labels. Write your tape's name by hand, the way you'd scrawl on a real cassette. Keep it personal. Share when you choose. Record and keep tapes on your device without creating an account. Sharing uses an online delivery service. Link Tape transfers and newly created Group Tapes use encryption to protect their audio in transit through that service. Everyone in a new encrypted Group Tape needs a compatible version of Taeppl. Make a tape. Pass it on. Come back to it years later.
