About

Oh geez... I am terrible at these. I am a father of five. Most are grown and one grandkid with another on the way! So that's cool. I like to build arduino projects. Over the last couple years, I started making apps. It started as a, " can I?" And turned into, " yes! And this should exist! And this! And this!" Then my buddy wanted one of my apps and said you should make a website. So now, here I am trying to tell whoever listens, hey, come look at my pretty toys and you can have one too if you want!

Does a "great product" fail if it doesn't build a daily habit?

Early on, we measured success by how many features users activated during onboarding. But we noticed a trend: users loved the product during testing, left 5-star feedback, and then completely forgot to open it the next week.

The problem wasn't utility the tool solved a real problem it just required intentional effort instead of fitting into existing habits.

How do you bridge the gap between a tool that "works great" and a tool people naturally open every morning?

Is Grandma asking for help with her phone again?

I have several apps. The app I am spotlighting here I specifically made for the less technologically savvy among us. Big buttons, easy to read font, simple controls that explain what is happening. Grandma should not have to try to dig through settings she doesn't understand in order to use her phone. Will be launching in a couple days, so that's pretty cool!

My build philosophy in everything I do is: free, no ads, no analytics, no account, no subscription, no paywall, no telemetry, no internet. Just trying to leave the digital world a little bit better than I found it.
