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.; Geographic Calculator no pricing is published for any edition, so buyers negotiate blind and the perpetual versus subscription decision is made without a public list to anchor against.
  • They diverge on capability: AllTrails covers Trail discovery, Geographic Calculator covers Geodetic parameter database.
  • Prices and features above were last checked on 1 September 2026.

Geographic Calculator

  • An offshore survey contractor delivering positions to an operator that requires a documented transformation path and residual accuracy, not just a reprojected filenot AllTrails
  • A pipeline operator reconciling decades of legacy survey data captured in several superseded datums into one current reference framenot AllTrails
  • A seismic processing team converting SEG-P1 navigation and SEG-Y headers between local grids and a global frame without silently losing metresnot AllTrails
  • A software vendor that needs correct geodesy inside its own product and licenses the GeoCalc SDK rather than building and maintaining a transformation cataloguenot 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.

Geographic Calculator

  • No pricing is published for any edition, so buyers negotiate blind and the perpetual versus subscription decision is made without a public list to anchor against.
  • Licence mobility is tied to being current on maintenance and support, which means a customer who lapses maintenance on a perpetual licence cannot move it to a new machine, effectively turning a perpetual purchase into a recurring cost.
  • It is a transformation engine, not a GIS: there is no meaningful analysis, cartography or editing, so most buyers end up also owning Global Mapper and paying twice for overlapping data handling.
  • The desktop product is Windows only, which is awkward for organisations standardised on macOS or Linux geospatial pipelines despite the cloud option covering only part of the workflow.
  • Blue Marble acquired Avenza in 2026 and is integrating a field data collection product, so engineering attention is spread across a wider portfolio than when Geographic Calculator was one of two products.

Answered from the vendors’ own pages

AllTrails: Is AllTrails free to use?

AllTrails offers both free and paid membership options. The basic free tier allows users to explore trails, see maps, and access core features for discovering hiking and outdoor activities.

Geographic Calculator: Is Geographic Calculator the same as Global Mapper?

No. Global Mapper is a general desktop GIS. Geographic Calculator is a dedicated geodetic conversion and datum transformation tool with audit reporting.

AllTrails: Can I create custom routes on AllTrails?

Yes, AllTrails allows users to build and edit custom trails. The platform provides route converter tools and options to print custom maps for your own trail designs.

Source
Geographic Calculator: Can I still buy a perpetual licence?

Yes. Blue Marble offers perpetual as well as subscription licensing, but a perpetual licence can only be moved between machines while maintenance is current.

Geographic Calculator: Why not just use QGIS or PROJ?

For routine reprojection they are fine. Geographic Calculator is bought when the transformation path, its accuracy and a documented audit trail must be defensible to a client or regulator.

Geographic Calculator: Is there a cloud version?

Yes, Geographic Calculator Cloud provides browser access to the transformation catalogue.

Geographic Calculator: What changed with the Avenza acquisition?

Blue Marble acquired Avenza Systems in 2026, adding Avenza Maps mobile field data collection to the portfolio. Ask about roadmap commitments before signing a long maintenance term.
