The short version

  • Only AllTrails has a free tier, so it costs nothing to try first.
  • Each has a real cost: AllTrails the App Store listing shows AllTrails is a free download with an in-app Pro subscription; the visible listing text does not state the Pro price, so the reader must check in-app purchases for the current rate.; Correlator3D the standard licence caps at 61 megapixel sensors, so an operator moving to a medium or large format camera has to buy a different and separately quoted licence rather than paying an upgrade fee.
  • They diverge on capability: AllTrails covers Trail discovery, Correlator3D covers Aerial triangulation.
  • Prices and features above were last checked on 1 September 2026.

Correlator3D

  • An aerial survey company processing large photographic blocks where per-project cloud credits would be more expensive than owning a licencenot AllTrails
  • A national or regional mapping agency that needs software it can run offline on classified or restricted imagerynot AllTrails
  • A drone service provider producing bare-earth terrain models for volumetrics and corridor mapping at high throughputnot AllTrails
  • An organisation that wants a perpetual licence because a multi-year subscription cannot be justified against its capital budgeting rulesnot AllTrails

Where each one falls short

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

AllTrails

  • The App Store listing shows AllTrails is a free download with an in-app Pro subscription; the visible listing text does not state the Pro price, so the reader must check in-app purchases for the current rate.

Correlator3D

  • The standard licence caps at 61 megapixel sensors, so an operator moving to a medium or large format camera has to buy a different and separately quoted licence rather than paying an upgrade fee.
  • It is Windows desktop only with no cloud processing option, so throughput is bounded by the workstation and GPU you buy, and there is no way to burst capacity for one large job.
  • There is no collaboration layer, client portal or field application, so deliverable sharing, review and version control all have to be handled by other software.
  • The interface and workflow are built for photogrammetry specialists; an occasional drone operator will find the learning curve steeper than a consumer-oriented mapping package.
  • The perpetual licence includes only one year of support and updates, and staying current afterwards means paying maintenance, so the headline $5,900 is not the whole long-term cost.
