Log and leak rate
The paid core is the job log. You can record refrigerant added and recovered per job, then track leak rate details and a repair deadline in one place. If you want the full workflow, see refrigerant log and leak rate tracking.
Cylinders and recovery
Yes, the app is built to track cylinder weights and recovery details alongside the rest of your service records. That makes it easier to keep the job history together in one cylinder tracking view.
Audit PDF and certification card
You can export an audit PDF and a technician certification card from the app. These exports are meant to help you share a clean record set without rebuilding notes by hand. See audit PDF export and certification card.
