Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

iAuditor by SafetyCulture

  • The free plan is limited to 10 users and 5 active templates
  • AI credits are metered per seat per month, at 300 on free, 500 on Premium and 800 on Enterprise
  • Unlimited templates and advanced analytics require Premium at $24 per seat per month billed annually
  • Paying monthly rather than annually raises Premium from $24 to $29 per seat
  • The 99.9% uptime commitment and 24/7 support are Enterprise only

Propeller Aero

  • Platform pricing is not published and is scoped by sites and users, so a contractor with many short-lived sites can be quoted very differently from one with a few long ones, and neither can benchmark against a list price
  • The corrections network is free only while you hold a current platform licence, so cancelling the platform subscription reintroduces a 1,000 dollar per year per group hardware cost that many buyers do not model
  • AeroPoints are a hardware purchase at 1,000 dollars each and most sites need several, so the true entry cost includes several thousand dollars of equipment on top of a subscription
  • It measures rather than designs, so a contractor still needs Civil 3D, Trimble Business Center or an equivalent to produce and revise the design surfaces the measurement is compared against
  • Accuracy depends on flight planning, ground control placement and weather, and a poorly flown survey produces a confident wrong volume, so an organisation still needs someone who understands survey error rather than only a drone pilot

Answered from the vendors’ own pages

iAuditor by SafetyCulture: Is Mitti (formerly iAuditor) free?

Mitti offers a free tier to start inspections and manage issues. Pricing for premium or team plans is not displayed on the vendor website.

Source
Propeller Aero: How much does Propeller cost?

The platform is quoted and not published. AeroPoints are 1,000 US dollars each, with the corrections network included for twelve months and thereafter free while a platform licence is current, otherwise 1,000 dollars a year per group.

iAuditor by SafetyCulture: What is the cost of Mitti for small teams?

Mitti does not publish per-user or team-based pricing on its website. The vendor directs users to book a demo to discuss plans and costs.

Source
Propeller Aero: Do I need AeroPoints?

No, you can use conventional surveyed ground control, but the AeroPoints workflow is the main reason contractors choose Propeller over generic photogrammetry.

iAuditor by SafetyCulture: Does Mitti charge per inspection or per user?

Mitti's pricing model (per-user, per-inspection, or flat-rate) is not disclosed on the vendor site. Users must request pricing information directly from sales.

Source
Propeller Aero: Is it survey grade?

Propeller states centimetre-level accuracy with correct ground control. Whether that satisfies a contract depends on your specification and on how the survey was flown, not on the software alone.

Propeller Aero: Who owns the data?

You retain your survey data and can export surfaces and point clouds, but check the export formats and retention terms in your contract before closeout, because bulk historical export is not a self-service one-click operation.
