Software, carefully made.

Jeremy Barr LLC is an independent software company in Massachusetts. We build small, focused mobile apps — tools that do one job well, respect your time, and keep your data yours.

What we're building

Our apps are local-first by design: no accounts, no ads, no data harvesting. Your information lives on your device, and export is always available.

Our first app — a symptom and medication tracker for perimenopause — arrives on the App Store in fall 2026.
