+- **CommCare**: open-source, developed by Dimagi, and good for collecting survey
+  data. It does not, however, use the open XForm / XLSForm standards like ODK,
+  Kobo, and Ona. Very good at collection of "longitudinal data" (data over time),
+  which ODK has only recently began to address with Entities.
+  However there are two key missing features:
+  (1) it's not well set up to handle geospatial data. It is possible to collect a
+  GPS point of users in the field, but not possible to select geometries to map.
+  (2) it's not configured to coordinate a team of users for field mapping, but more
+  for individual users to map.
+  Despite this we will definitely look for opportunities to learn from / collaborate
   into the future.
