The free plan gives every calculator AmpSize has, no account needed to use one. A signed-in free account keeps up to 10 saved calculations and 1 project. Its PDF reports carry an AmpSize footer line.
Pro adds:
- Unlimited saved calculations and projects.
- Project defaults for every new calculation in a project.
- The project schedule, asset register and cable list as CSV files.
- One PDF report for a whole project, with its A3 plan sheets.
- A change log on each project.
- A branding block on PDF reports, with your own company details and logo.
- The plan tools: an underlay, a quote and a share link.
- Part detail and the spec builders in the library.
- Priority support.
AmpSize does not move a calculator from the free plan to the paid plan. No report carries a watermark on either plan.
Sign in with a Google account, or with a one-time link sent to an email address. The email link works once and expires in 15 minutes; there is no AmpSize password to set. The account page can sign out one device, or every device at once with "Sign out of all devices". Deleting an account and its data is not self-service: email AmpSize to ask for it.
If an account drops from Pro to free, every saved calculation and every project stays. Both can still be opened and printed. What pauses is the Pro-only features above, not the work already saved.
