The FBIS mobile application is a quick and easy way to upload freshwater biodiversity data from field monitoring sites directly to the FBIS platform, eliminating the need for datasheets and spreadsheets. Biodiversity data for fish, invertebrates, algae, anurans and plants can be added for both rivers and wetlands, and SASS biomonitoring data can be added for rivers. The app mimics standard data sheets, accommodating details about sampling site, sampling method, sampling effort, environmental data, photographs, notes and more. Sampling data can be synchronized with FBIS platform when back at the office via a wifi connection, or directly from the field using mobile data.

Verdict
The clearest difference is update cadence: FBIS at every 3 weeks against CASI's every 6 months. CASI's advantage is device support (4 vs 2). On price, ads, in-app purchases and iOS requirement there is nothing between them.
