D-Tree International - As D-Tree notes, “features sometimes trump cost, one has to make the choice between enhanced UI vs. minimal UI, advanced features vs. basic functionality, in our case we needed to get more out of the phone and Android/ODK allowedus to do that.”Berkeley Human Rights Center - The choice to switch to ODK was driven primarily by cost, usability, latency, errors and scale. That is, “there is a point where the money saved on paper production and shipping, and the money saved by removing the steps of data-entry by hand, balances everything out...the increase in data accuracy is an argument for spending the money.”Johns Hopkins Center for Clinical Global Health Education – JHCCGHE’s explains that ODK “is used for patient data gathering, and to give an exam after watching a video course on the phone, to make sure the user understood the content.”Academic Model for the Prevention and Treatment of HIV - AMPATH had extensive previous experience with datacollection. “Before using ODK, we had created data collection functionality on Palm TX devices using Pendragon Forms.GPS information was collected using eTrex devices, and these devices were connected via cable to the Palm device.”
Open Data Kit (ODK) is a suite of tools that allows data collection using mobile devices and data submission to an online server, even without an Internet connection or mobile carrier service at the time of data collection. Consists of: ◦ ODK Build – Authoring forms ◦ ODK Collect – Mobile engine ◦ ODK Aggregate – Data server ◦ ODK Manage – For supervision of research assistants ◦ Among other tools

– Harder to skip questions– Range checking– Eliminates branching errors– Eliminates transcription errors– Immediate access to data from the server – rapid data aggregation and analyses– Very portable– Minimize workforce -Better supervision is possible
– Unlimited data types; Form + GPS + picture + video + string+ numeric + audio + barcode– Get GPS location of respondent easily– Cleaner data – standardization of data– Easy connection to other health records e.g. openMRS

Open Data Kit provides organizations with a new way to build information services for developing regions. The modular, extensible and open-source design allows picking and choosing tools best suited for specific deployments. ODK differs from other platforms and has unlimited set of tools Ongoing deployments has proven success. ODK system architecture of enables a large and varied set of applications for developing regions.
