Roast my GPS art planner! GPS Art Wizard is not trying to be the biggest shape library or another prompt-to-GPX generator.

The rest was a 2.5 year slog built on decades of coding, sport science , and AI sinc

I built a Google Maps rank tracker that compares mobile and desktop results street by street I built a Google Maps rank tracker that shows mobile vs desktop rankings street by street — looking for blunt feedback Google Maps rankings are much more local than most reports make them look. A business can rank #2 from one street and become almost invisible a few blocks away. Mobile and desktop results can also tell completely different stories. I kept seeing tools reduce all of this to a sin

I built an explorable 3D globe of the world economy – click any country, get its economy, or play 18 geography games. 10 weeks, zero runtime API calls globenomics.world — spin a 3D globe, click any country, and get its actual economy: GDP, wages, inflation, its biggest companies, and exactly where it ranks against every other country on 34 metrics. Then there are 18 geography games built on the same data — including one where you name as many countries as you can in three minutes, and one
