Notice: Due to a shift in program budget and priorities for 2026, the NMDC is not actively developing or maintaining the Field Notes Mobile App. Please visit the NMDC website for more information about our other products to submit, access and share microbiome data. --- NMDC Field Notes is an iOS/iPadOS app microbiome researchers can use to record metadata about the biosamples they collect while they are working in the field. It is a mobile alternative to the browser-based NMDC Submission Portal web app, designed specifically to streamline the process of documenting metadata at the time of biosample collection. Its features (all of which were designed in collaboration with microbiome researchers) include: ORCID login, entry of study and biosample metadata, one-tap entry of user information, geographical coordinates, and dates, user interface forms that are dynamically generated from a LinkML schema, and automatic syncing of study and biosamples metadata with the NMDC Submission Portal.

Verdict
The clearest difference is in-app purchases: NMDC Field Notes at none against Flight Log's 2. NMDC Field Notes also leads on iOS requirement (14.0 vs 18.2). Flight Log's advantage is update cadence (every 6 weeks vs every 5 months). On price, ads and device support there is nothing between them.
