ArcGIS Survey123

Great application provided you have a halfway decent developer. Has tons of "out of the box" solutions that are a tad clunky. Knowing some one that can discuss a data management strategy and configure it accordingly can turn this into an extremely efficient app for field data collection at a variety of levels of precision (all depends on what inputs/sensors its reading from). only 4 because there is always room for improvement.

Only works about 50% of the time. Glitches out, shuts off, and then doesn't save the survey you were working on.

Have been using this app for work on and off for 2 years. Quite honestly, the people giving 1 star reviews must have learning difficulties - yes, the app is not perfect, but anyone with half a brain should be able to make it work for them. If you are precise and careful with data entry (as anyone should be when collecting data), the app does a good job. I gave it 4 stars because the back end website where you view/download uploaded data is a little complicated to navigate, but not impossible.
