The short version

  • Only IndoorAtlas has a free tier, so it costs nothing to try first.
  • Each has a real cost: IndoorAtlas requires labor-intensive fingerprinting process, walking every corridor to build magnetic map for each venue; NAPA the Internet Archive's capture of NAPA's homepage on 1 January 2020 named six distinct maritime software products, NAPA Loading Computer, NAPA Emergency Computer, NAPA Logbook, NAPA Fleet Intelligence, NAPA Voyage Optimization and ClassNK-NAPA GREEN, with no price figure published for any.
  • They diverge on capability: IndoorAtlas covers Core Functionality, NAPA covers Ship design.

Where each one falls short

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

IndoorAtlas

  • Requires labor-intensive fingerprinting process, walking every corridor to build magnetic map for each venue
  • Magnetic signatures degrade over time, requiring periodic re-fingerprinting as the environment changes
  • Magnetic interference from external sources and devices disrupts positioning accuracy
  • Positioning inconsistent across different smartphone models due to magnetometer heterogeneity
  • High cost to deploy and maintain, with expensive implementation for wide-scale adaptation

NAPA

  • The Internet Archive's capture of NAPA's homepage on 1 January 2020 named six distinct maritime software products, NAPA Loading Computer, NAPA Emergency Computer, NAPA Logbook, NAPA Fleet Intelligence, NAPA Voyage Optimization and ClassNK-NAPA GREEN, with no price figure published for any.

Answered from the vendors’ own pages

IndoorAtlas: How does IndoorAtlas determine positioning without beacons or hardware?

IndoorAtlas uses patented geomagnetic fusion technology that maps the Earth's magnetic field patterns inside buildings through a process called magnetic fingerprinting. The technology combines magnetometer data with other sensors like WiFi and Bluetooth for robust positioning.

Source
IndoorAtlas: What is the initial setup process for IndoorAtlas?

Setup requires fingerprinting the venue by systematically walking through all corridors and spaces to build a magnetic map. The platform then identifies problematic areas through red (conflicting data), blue (insufficient coverage), and path orientation errors that require correction before the map is production-ready.

Source
IndoorAtlas: What are IndoorAtlas's pricing plans?

IndoorAtlas offers production subscriptions starting at 349 euros per month per venue, with a development plan at 400 euros per month. A free tier is available for developers to start building.

Source
IndoorAtlas: How accurate is IndoorAtlas positioning?

IndoorAtlas claims industry-leading accuracy down to 50 centimeters using its 6-layer sensor fusion core across diverse environments, though accuracy varies based on building magnetic patterns and requires careful calibration.
