Building Apps That Don't Suck (and Sometimes Even Delight)
I craft mobile experiences that are actually useful, blending tech with a human touch. 10+ years of making apps, and I'm still not bored.
About JH-APPS
Making apps that make a difference (for real).

I'm Jari, the guy behind JH-APPS. I build apps that solve real-world problems – whether it's helping kids learn or giving adults a moment ofzen. Over a decade in, and I'm still obsessed with finding new ways to use technology for good (and for fun).
Innovation Driven
Pushing the boundaries (without breaking everything).
Impact-Focused
Creating apps that *actually* improve lives.
Mobile First
Because it's the 21st century, obviously.
User Focused
Designed for humans, not robots (yet).
Apps That Actually Help
Digital tools designed for real-world impact.
Stories That Make It All Worth It
Real people, real impact. These are the stories that keep me building.
