The short version

  • Only MAPS.ME has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; MAPS.ME mobile-only - no web or desktop navigation client
  • They diverge on capability: Geographic Calculator covers Geodetic parameter database, MAPS.ME covers Core Functionality.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

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.

MAPS.ME

  • Mobile-only - no web or desktop navigation client
  • Free tier limits offline map downloads and shows monetization prompts
  • No native Windows, macOS, or Linux app
  • Map data comes from the OpenStreetMap community rather than a commercial map provider

Yes. MAPS.ME has a free tier, so you can try it without paying. Geographic Calculator starts at On request.
What is Geographic Calculator best used for?
Geographic Calculator is most often used for an offshore survey contractor delivering positions to an operator that requires a documented transformation path and residual accuracy, not just a reprojected file, a pipeline operator reconciling decades of legacy survey data captured in several superseded datums into one current reference frame, a seismic processing team converting seg-p1 navigation and seg-y headers between local grids and a global frame without silently losing metres, a software vendor that needs correct geodesy inside its own product and licenses the geocalc sdk rather than building and maintaining a transformation catalogue. Of those, an offshore survey contractor delivering positions to an operator that requires a documented transformation path and residual accuracy, not just a reprojected file and a pipeline operator reconciling decades of legacy survey data captured in several superseded datums into one current reference frame are not what MAPS.ME is typically brought in for.
What can Geographic Calculator do that MAPS.ME cannot?
Geographic Calculator covers Geodetic parameter database, Batch coordinate conversion, Datum transformation with accuracy reporting, Time-dependent transformations. MAPS.ME covers Core Functionality, User Interface.

Answered from the vendors’ own pages

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.

MAPS.ME: Is MAPS.ME free to download and use?

MAPS.ME is available as a free download for both iOS via App Store and Android via Google Play. No pricing information is published on the MAPS.ME website, suggesting a free service model.

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.

MAPS.ME: What features are included in MAPS.ME?

MAPS.ME is marketed as 'not just an app but a friend in all your adventures.' Full feature details require downloading the app from App Store or Google Play. Specific limitations or premium features are not disclosed on the website.

Source
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.

MAPS.ME: How does MAPS.ME make money if the app is free?

MAPS.ME does not publish pricing or monetization details on its website. The app is available free on both iOS and Android platforms, but the business model for generating revenue is not disclosed publicly.

Source
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.
