### 5/5 — Finally a clean HVAC app that actually works offline

*2025-12-19*

I’ve been looking for a solid all-in-one toolkit like this for a while. Most other hvac calculator apps are either super outdated or require internet. which is useless when l’m in a basement or on a commercial roof with no signal.
The UI is super clean. I really like the visual sliders for superheat and subcooling—makes checking the charge way faster than typing in numbers. The built-in ductulator is also spot on for quick duct sizing checks. Also handy to have the capacitor test and airflow tools in the same place. Replaced 3 different apps on my phone. Highly recommend for any service tech.
