ELERTS

ELERTS develops emergency alert software systems centered around smartphones and crowd-sourcing. The job it does: designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. They also list Android, Crowdsourcing, Email, iOS and mHealth, so expect those to show up in the feature set. They are a small team, 11 to 50 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

ELERTS is based in Weymouth, Massachusetts. More on elerts.com.
