The ads on the app help to pay for server costs to support the app, he said. The ads on Monday were from companies including Israel Bonds, Cisco, Google and Outdoor Wood Furnace. "We have limited resources and want to make a little cash to support our service, and we're not making any money. We're doing it to help people save their lives. "
The first version of the app was written for Android two years ago. "It took us 48 hours and it was a light version done during the last war in 2012," Sprung said. "What we're using to build it was nothing too fancy."
Sprung said the biggest challenge for the apps is the volume of downloads. "The push notification has to go very fast and to very many people and we're learning how to overcome that," Sprung said. "We've been tweaking it over the past two years. There are a lot of things coming up to increase the functionality."
When asked what kinds of improvements might be included for the app in the future, Sprung declined to elaborate. "Hopefully you won't see it because there won't be another war," he said. "We hope we don't have to use it."
