Aulé ships with built-in material libraries for Plasterers, Dry-Liners, and Plumbers. You can add custom trades and materials in Settings — the app adapts to any trade that works with measured surfaces.
LiDAR gives the best measurement accuracy, but Aulé also works with standard ARKit on any iPhone with an A12 chip or later. You can always enter measurements manually if you prefer.
No. All your data — jobs, invoices, bank details, measurements — is stored locally on your device. Bank details are encrypted using the iOS Keychain. Nothing is uploaded to any server unless you explicitly share a PDF.
Set your CIS status in your profile — Gross (0%), Standard (20%), or Unregistered (30%). Aulé automatically applies the correct deduction to every invoice and includes the CIS compliance statement on your PDFs. It also reminds you to file Nil Returns when you've had no CIS activity in a month.
Aulé is free to download from the App Store. All core features — AR measurement, invoicing, quoting, CIS compliance, carbon tracking, and material management — are included at no cost.
Aulé tracks your quarterly turnover against the £50k MTD threshold and alerts you when you're approaching or exceeding it. While it doesn't submit directly to HMRC, it provides the quarterly breakdowns your accountant needs.
