Where each one falls short

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

ArcGIS Field Maps

  • Field Maps has no price of its own, so a project budget built from the product page misses the Creator seats, the Mobile Worker seats and the ArcGIS Online credits or Enterprise infrastructure that actually cost money
  • It only works against Esri feature services, so an organisation whose data is in PostGIS or a database without an ArcGIS layer must publish through Esri first, which is a platform decision rather than an app choice
  • Named user licensing means occasional or seasonal field staff still consume a full annual seat, and organisations with a large pool of infrequent collectors pay for capacity they use a few weeks a year
  • As a forms tool alone it is more rigid and more expensive than dedicated mobile forms products, so its value collapses if you are not already committed to ArcGIS
  • The consolidation of four apps into one changed established workflows, and organisations that had built processes around Collector or Workforce have had to rework them on Esri's timetable rather than their own

What3words

  • The free API plan includes no coordinate conversion, only AutoSuggest, and is rate limited to 5 requests per second
  • Converting to and from what3words addresses starts on the Basic plan at $9.99 per month for 1,000 conversions
  • Priority and developer support require the Standard plan at $45 per month
  • 24/7 phone support requires the Plus plan at $125 per month
  • Custom invoicing and annual payment require the Premium plan at $300 per month
  • Overage pricing is not published; the page states only that a fair usage policy applies
  • The three word address scheme is proprietary and licensed rather than open data
