The short version
- Each has a real cost: On-Screen Takeoff perpetual licensing is no longer offered on current releases, so long-standing users who paid once now face a recurring annual cost they never budgeted, and staying on an old version means no support for newer PDF formats; 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: On-Screen Takeoff covers Drawing takeoff, 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.
On-Screen Takeoff
- A drywall contractor measuring wall area and openings across a 300 sheet set where manual takeoff would take a weeknot Propeller Aero
- An estimator who receives a late addendum and needs to know which rooms changed rather than re-measuring the whole floornot Propeller Aero
- A flooring subcontractor maintaining reusable conditions with waste factors so quantities and material orders stay consistent between estimatorsnot Propeller Aero
- A trade contractor that wants takeoff quantities split by phase so progress billing matches the way work is actually releasednot Propeller Aero
Propeller Aero
- A quarry that reconciles stockpile inventory monthly for its accounts and wants the volume evidence to survive an auditnot On-Screen Takeoff
- An earthworks contractor claiming progress payments on cubic metres moved who needs an independent measurement the client will acceptnot On-Screen Takeoff
- A civil site checking whether a subgrade is within tolerance of the design before the surfacing crew arrivesnot On-Screen Takeoff
- A mine that wants weekly volume reporting without a survey crew on the ground every weeknot On-Screen Takeoff
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
On-Screen Takeoff
- Perpetual licensing is no longer offered on current releases, so long-standing users who paid once now face a recurring annual cost they never budgeted, and staying on an old version means no support for newer PDF formats
- ConstructConnect does not publish a price, and the product is increasingly sold inside a bundle with lead data and estimating, so buyers who want takeoff alone often find the quote priced around a package they do not need
- It is Windows desktop only, with no macOS version and no meaningful browser or tablet workflow, which rules it out for firms standardised on Apple hardware
- The interface has changed little in years and estimators coming from browser-based tools find the condition setup and layer management slow to learn, so onboarding a new estimator takes longer than the software cost would suggest
- ConstructConnect sells lead data, takeoff and estimating as a portfolio and has consolidated several acquired products, so a buyer committing to On-Screen Takeoff should ask directly where it sits against the newer cloud takeoff products in the same portfolio
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

Questions people ask
- Is On-Screen Takeoff or Propeller Aero better?
- Neither clearly leads. On-Screen Takeoff starts at On request and Propeller Aero at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, On-Screen Takeoff or Propeller Aero?
- On-Screen Takeoff starts at On request and Propeller Aero at On request.
- Does On-Screen Takeoff or Propeller Aero run on more platforms?
- On-Screen Takeoff runs on Windows. Propeller Aero runs on Web, iOS, Android.
- What is On-Screen Takeoff best used for?
- On-Screen Takeoff is most often used for a drywall contractor measuring wall area and openings across a 300 sheet set where manual takeoff would take a week, an estimator who receives a late addendum and needs to know which rooms changed rather than re-measuring the whole floor, a flooring subcontractor maintaining reusable conditions with waste factors so quantities and material orders stay consistent between estimators, a trade contractor that wants takeoff quantities split by phase so progress billing matches the way work is actually released. Of those, a drywall contractor measuring wall area and openings across a 300 sheet set where manual takeoff would take a week and an estimator who receives a late addendum and needs to know which rooms changed rather than re-measuring the whole floor are not what Propeller Aero is typically brought in for.
- What can On-Screen Takeoff do that Propeller Aero cannot?
- On-Screen Takeoff covers Drawing takeoff, Revision overlay, Condition libraries, Automatic scaling. Propeller Aero covers Photogrammetric processing, AeroPoints ground control, Volume measurement, Design surface comparison.
Answered from the vendors’ own pages
On-Screen Takeoff: Can I still buy a perpetual licence?
No. Current releases are annual subscription. Older perpetual licences continue to run but do not receive updates.
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.
On-Screen Takeoff: Is it sold separately from Quick Bid?
It can be, but ConstructConnect increasingly quotes it as part of a takeoff and estimating package. Ask explicitly for standalone pricing if that is what you want.
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.
On-Screen Takeoff: Does it run on a Mac?
Not natively. It is a Windows application and Mac users run it under virtualisation, which is unsupported in practice for large drawing sets.
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.
On-Screen Takeoff: Will it read a scanned drawing?
Yes, but measurement accuracy on a scanned raster set depends entirely on the scan quality and on setting scale from a verified dimension.
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.
