1. Create and verify your account
Enter your details on the trial page, complete human verification and confirm your email. Set a strong password. Account registration alone does not grant app access or start billing.
2. Complete the Stripe trial checkout
After signing in, continue to Stripe. Supply a payment method and billing address, review the recurring terms and confirm. Eligible customers receive a 30-day free trial, followed automatically by $99 USD/month until canceled. Server-side checks must approve the subscription before the app opens.
3. Map and inspect the building
Launch the app from your account. Place the corners around the perimeter of the building or unit you are evaluating. Review the completed polygon. Set the supported chart inputs from a source you understand; do not guess merely to obtain a result.
4. Choose a point, date and interpretation language
Use GPS where suitable or choose a manual location. Inspect the reported accuracy, select a supported date and request the reading. Export it if useful, keeping your assumptions with your notes.
When a reading needs another look
An uncertain GPS fix, inconsistent compass heading or unsupported combination should lead to an input check. See the mobile troubleshooting guide and compass guide. Use the contact form for a reproducible software issue.
Your subscription stays under your control
Open Account and choose Manage billing to access Stripe’s customer portal. Cancel before the trial expires to avoid the first charge, or before a monthly renewal to avoid the next charge. Closing the app or not using it does not cancel billing.
