Looking for an Android app that handles offline transects with taxon autocomplete; ODK Collect slows down with our 520-species list and I need GPS averaging every 10 m. If you’ve got a setup that works with gloves and spotty signal, please share the app and any form design tips or a template.
What worked for me was staying on ODK Collect but moving the 520 taxa into an external CSV and using fast external itemsets with search() so autocomplete stays instant offline; GPS averaging still isn’t native, so I fake it with a 5‑point repeat and average in a calculate. https://docs.getodk.org/fast-external-itemsets/ — want my XLSForm?
