UpSense is a local-first stream recording tool for turning daily thoughts, image fragments, voice moments, and event points into clearer personal threads.
Send text and images as naturally as chatting with yourself, then let anything that does not yet have a place land in the default Quick Notes stream. You can also create separate streams for work, life, ideas, or any theme you want to let settle on its own.
The event network records important points and lets you review them as a horizontal timeline. It is useful for habit reviews, noticing stage changes, and connecting scattered moments into a thread you can revisit.
UpSense works local-first, does not require account registration, contains no ads, and can sync streams, records, images, voice, events, to-dos, and app settings across your devices through Apple's iCloud private database. This content is not uploaded to servers owned by us.
The free version lets you send text and image records in the default Quick Notes stream and record event points for 5 consecutive calendar days from the first event day. UpSense+ unlocks unlimited streams, recording in any stream, and continuous event recording.
