I built a virtual pet kitten for iPhone and Apple Watch that gets hungry when I should eat

A kitten on your iPhone and Apple Watch: hungry when you should eat, moving when you move, asleep when you should be. Six free kittens, six more in boxes.

I got tired of my seating chart breaking every time one guest dropped out, so I built one that treat

I did the seating chart for a wedding last year in a spreadsheet, and the part that nearly killed me wasn't drawing the tables. It was that every change broke something else. Move one person and the two aunts who can't be near each other are sharing a table again, and you don't find out until you reread the whole list. So I built SeatSort around rules instead of dragging. You paste the guest list, draw the room, and write down what actually matters: keep these two apart, seat t

We built a shared project workspace because being the human clipboard is a terrible job

I made a daily guessing game as a side project, and apparently none of us knows how many islands the

I like games like Maptap and Krillion, so I built Moonshot: five numerical questions a day, ten seconds per question, and a score based on how close your guesses are. You don’t have to know the answer—just take your best shot. One question asked how many islands the Philippines has. Of the 27 people who played, nobody guessed within 10% of the answer: 7,641. It’s been a fun side project, and I’d love feedback from people who enjoy daily games. Is ten seconds enough time to make a good gu
