Hey all! I built an app to solve this problem! If you ever need to remember a small piece of information like when or where you did something, just type it in and the time/location will be logged. You can then search for it and easily recall when/where it was. A friend of needgap suggested I post here!
App Store (iOS): https://apps.apple.com/au/app/spacetime-logger/id1479321094
Logger: Spacetime Notes helps you write notes quickly and capture exactly when and/or where you wrote them. During the pandemic, you can also use it to record when, where, and who you've been in contact with by simply typing their name (like a text message).
I've personally used it to remember conversations with people, record the time I start something, track progress of my projects, jot down fleeting thoughts, mark where I've parked, and pinpoint cool places I've visited. Basically, anything you want to record quickly that you might need to recall in future. I like to think of it as a cache/extension of your biological memory.
I'd appreciate any feedback!
