The short version

  • Each has a real cost: Assignar it is built for contractors who own crews and plant, so a general contractor coordinating subcontractors gets little from it beyond its own self-perform scopes.; 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
  • They diverge on capability: Assignar covers Crew and equipment scheduling, Propeller Aero covers Photogrammetric processing.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Assignar

  • A civil contractor scheduling crews and plant across multiple sites from one dispatch boardnot Propeller Aero
  • A concrete or earthworks subcontractor replacing paper dockets that arrive three days latenot Propeller Aero
  • A contractor that must prove operator competency and induction status on regulated sitesnot Propeller Aero
  • A self-perform contractor comparing actual crew hours against estimated production ratesnot Propeller Aero

Propeller Aero

  • A quarry that reconciles stockpile inventory monthly for its accounts and wants the volume evidence to survive an auditnot Assignar
  • An earthworks contractor claiming progress payments on cubic metres moved who needs an independent measurement the client will acceptnot Assignar
  • A civil site checking whether a subgrade is within tolerance of the design before the surfacing crew arrivesnot Assignar
  • A mine that wants weekly volume reporting without a survey crew on the ground every weeknot Assignar

Where each one falls short

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

Assignar

  • It is built for contractors who own crews and plant, so a general contractor coordinating subcontractors gets little from it beyond its own self-perform scopes.
  • It is not an accounting or payroll system, so the value depends on a clean integration to your finance system and on someone owning the reconciliation when hours disagree.
  • Australian origins show in terminology and compliance defaults, and North American users spend setup time translating concepts such as tickets and inductions into local equivalents.
  • Offline capture works, but photo-heavy forms on poor connections remain the weak point and should be tested on your worst site before a full rollout.
  • Supervisors have to maintain the schedule for the reporting to mean anything, and dispatchers used to a whiteboard resist that for months unless the change is enforced.

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

Assignar: Is this for general contractors or subcontractors?

Speciality and self-perform contractors. The unit of work is a crew and a machine on a shift, which is not how a general contractor coordinates trades.

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.

Assignar: Does the mobile app work without signal?

Yes, entries are captured offline and synchronised later. Test it with photos attached on your worst site, because that is where sync problems appear.

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.

Assignar: Does it handle payroll?

No. It captures hours and quantities and passes them to your payroll or enterprise resource planning system.

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.
