Why DayKeep

I’m Michael Prince, in Kennewick, Washington. I’ve been shipping software since 1995, and DayKeep is the software I always wanted to make.

For years I kept my day together the way most people do: a todo app, a notes app, something for texts, something for passwords. One by one they filled up with ads. The apps I opened every morning stopped feeling like they were made for me.

So I started building the ones I wanted, for my own use first:

• DayKeep

  Tasks, habits and notes for the whole day. It works offline and syncs to every device.

• DayKeep Voice

  Hold a shortcut and talk. It types where your cursor is, transcribed on your PC.

• DayKeep Messaging

  Texting for Android, minus the annoyances. Your texts stay on your phone.

• DayKeep Passwords

  Your logins, end-to-end encrypted, on every plan.

No ads, ever.

Not in any of them, and not later. The only thing DayKeep will ever tell you about is its own other apps, in places like About and this site, never inside your lists, notes or messages.

Passwords closes a loop for me. In 1997 I sold a password vault for Windows 95. It sold about ten copies, by mailed check. Nearly thirty years later, I keep my own logins in DayKeep Passwords.

In 2019 I stepped away from work to care for my dad.

When I came back to building, AI had changed the work, and at first that depressed me. I had spent decades learning this craft, and now a machine could do much of it. Then I started building with it, and the things I had wanted to make for years were finally within reach. DayKeep is built that way. I design it and decide every detail, and AI agents write much of the code with me. I think you should know how the software you trust is made.

I’m one person making software I use every day. If DayKeep earns a place in yours, paying for it keeps me building it, and it helps my family.
