NIWA Citizen Science App Citizen science projects allow members of the public to work on important scientific research. NIWA’s new Citizen Science App makes this easier than ever by enabling simple data entry for science surveys. How does the App work? When a researcher creates a citizen science survey, it is immediately available, through the Citizen Science App. Users can choose from a variety of surveys. Some, such as snow depth or storm assessment, will come and go during the year - others will remain year-round. Once surveys are completed, users can see their submissions on the Citizen Science website. Other research groups – professional or amateur – can also use this data for other scientific projects. Surveys can be restricted to specific user groups if required. As the data set grows it will become a useful tool for scientists all over the country through NIWA’s comprehensive API. If you're interested in finding out more, please email citizenscience@niwa.co.nz.

Verdict
The clearest difference is review sentiment: Drops at 75% against Citizen Science's 0%. Drops also leads on update cadence (every 8 days vs every 4 months) and chart position (#128 vs unranked). Citizen Science's advantage is in-app purchases (none vs 13) and ads (none vs shown). On price and device support there is nothing between them.
