Check & Charge / PT Pro alternative: free offline PT chart (no login)
Short answer: Copeland is retiring its Check & Charge app and retired PT Pro from October 1, 2026, moving their calculators into Copeland Mobile, which asks you to log in. If you only need a pressure-temperature chart and a superheat/subcooling check, Refrigerant PT Chart does that free, with no account, and keeps working with no signal once you add it to your home screen.
