Backendless was an easy decision as with the offer of a no cost service if the amount of data stored remained relatively low. If the data storage needs were to rise, the charges would be quite reasonable. Real time access to data allows us to keep tabs on how study participants are doing whenever necessary. For example, this allowed us to trouble shoot app problems with data delivery to from their phones to Backendless. As a result, we were able to improve app’s stability.
