We notify when you get 012345

A 2FA app with a twist. Notifications every time a great number comes up. Collect all the rare GETs! If you know, you know. The drudgery of having to newly authenticate with your bank or your email account; and the little spark of joy when you get a number like 780000 or 123451. What if you could see every time a truly awesome number comes up? Check 'em finds the best of the best, and sends you a notification whenever they appear. Customise what you want to see, and tap the notification to add the GET to your collection!

I've had a lot of fun optimising the performance of this app via algorithm analysis, massive parallelism, and cleverer pre-processing. The result? Now the processing stage while we calculate your notifications takes about 5 seconds - before, it could take over a minute. Follow Jacob's Tech Tavern on Substack for the write-up!
