About

StarLens Visual Notes & Tasks

Read full description

StarLens is a different kind of organizer, helping you visually keep track of the things that matter most. Why might a star system work for you when other methods of memory management don't? Consider memory athletes, super-memorizers that competitively remember and recall huge amounts of information. They use a system of imagery, visualization, and location based recall. While StarLens isn't meant to help you memorize 1,000 digits of Pi, it hopes to build on the concept to create something more. We don't all think the same. Try something a little different. Here's a quick list of a few of our features: - Unlimited levels of subtasks or child notes... this is how constellations are built - Each note or task is arranged into a constellation of stars automatically - A constellation can be put anywhere - Zoom out to see everything - Find what you need, when you need it - Search across everything - Notes can be dragged to reorder - Can be used offline - Automatic syncing and backup to our servers, so you never lose a thing And here are a few of our promises: - We know AI is a polarizing topic when it comes to notes, so let's address this straight on! We do not sell your data or "train AI" using your data, pure and simple. - We do not use your data in any way, except to provide our service / app to you - No ads ever - No tracking you or using your data to profile you - Complete transparency Please see the following for more information: Privacy Policy: [https://starlensapp.com/privacy-policy] Terms of Use / EULA: [https://starlensapp.com/terms-of-service]
