608Log

The only iOS app built for EPA 608-certified HVAC technicians that generates signed, legally-compliant service records — right on the job site. AIM Act ER&R COMPLIANT — 2026 UPDATE The AIM Act expanded mandatory refrigerant logging to all systems with 15+ lbs of HFC (R-410A, R-454B, R-32, R-134a).
