A first diagram free, no account
schemaunifilaire.app lets you draw a first diagram up to 15 circuits, with a one-floor plan and a watermark-free PDF, without creating an account. For a homeowner, a €19.99 lifetime licence incl. VAT (“DIY” plan) unlocks unlimited diagrams, circuits and floors. A simple way in for an occasional file.
The Electrician plan
For professionals, the Electrician plan (€29.99 a month or €299.90 a year incl. VAT) adds the installer's logo and details, a file per customer and sending invoices, including via Peppol. The terms require one account and one subscription per team member.
If schemaunifilaire.app suits you
For a few files a year, or to invoice from the same tool, schemaunifilaire.app makes sense. Amperio covers other needs: diagram and plan linked in the same project (side by side in schemaunifilaire.app), dictation and job follow-up with the team.
Moving from schemaunifilaire.app to Amperio
Ongoing files: export the diagram from schemaunifilaire.app as a PDF, then import it into Amperio. RCDs, breakers and circuits are rebuilt; you review the result before carrying on, and everything stays editable by hand. An existing plan, as a PDF or a photo, imports the same way.
Archives: nothing forces you to migrate them. Keep the old files in schemaunifilaire.app and open new projects in Amperio.
