## What is AC Tech Pocketbook Pro?

Your HVAC reference, calculators and service records — always available. No internet required.

AC Tech Pocketbook Pro is built for the tech who works where the Wi-Fi
doesn't reach. Rooftop, basement, pump room — verified refrigerant PT
data, the calculators you actually use, and a service record for every
unit you've ever touched. All on the phone in your pocket.

PT data you can trust with the charge
• Pressure-temperature tables and charts for R-22, R-134a, R-404A,
  R-407C, R-410A, R-32, R-454B and R-1234yf — generated from CoolProp
  reference data, source attribution included
• Dew vs bubble handled correctly for zeotropic blends — the number
  other apps get wrong
• Scrub the chart or step the table; gauge or absolute units, labeled
  so you can't mix them up

The calculations, done right
• Superheat and subcooling with live PT lookup — readings in, verdict out
• Target superheat vs manufacturer spec, capacitor tolerance, airflow
  and Delta-T, electrical and unit conversion
• Every calculation saves to history and can attach to the job it was for

Service records that outlive the phone
• Customers, equipment and jobs — measurements, photos and parts on one
  visit record
• QR asset tags: scan a unit and its whole history opens
• Clean PDF service reports your customers actually sign
• AES-256-GCM encrypted backups — move everything to a new device in
  minutes, passphrase-protected

Pay once. It's yours.
• No account, no ads, no subscription, no cloud lock-in
• SQLCipher encryption at rest; nothing leaves the device unless you
  share it
• Works fully offline — forever

Built for phone, tablet and iPhone Duo, light and dark — the layout
adapts, your work stays put.
