Hi PH! I'm Rob, a biomedical scientist from Liverpool. I built UnitConvert Pro because I kept switching between 5-6 apps for lab calculations, conversions, and dev tools. What makes this different: → 17 categories — Lab, IT, Trade, Photography, Music → 60+ real calculators, not just conversions → Searchable Periodic Table → 14 dev tools (UUID, hash, regex, JSON) → Offline, no ads, no tracking Free on Android and Windows desktop. What calculators would you add?
