For 25 years I Googled "random password generator" every time I needed a new password. One day I just built my own so I'd stop doing that. That became Boltkey.

Then I needed to practice songs in a different key, so I built SetKey.
Then I needed to track expenses without bloated software I'd never fully use, so I built Account Rendered.
Three problems, three tools, zero subscriptions. Sometimes the best app is the one that only does what you actually need.
