We need to develop simple hybrid app for ios/android. It's basically a simple web container that must show report details about our client's business. Each client's CEO has his own username and password to enter the data and once logged in these will be provided directly as an html page that will be running remotely from our servers. This must contain locally only an authentication page, a splash screen, the icons and service page in the case of network failure. All content will be shown directly from a specific website. We need also to keep the user signed somehow so that the password is not required in the future when opening the app. A 2-step authentication method must be used: sms, e-mail or google authenticator would be fine, but our favorite implementation (that will make the difference) would be the possibility to select a SSL client self-signed certificate to be used when entering the website. This is because, being the data about the business very sensitive, we already use mutual authentication through SSL client ACL when surfing our web services. Our clients already have their own client certificates installed on their phones. These are currently used inside the browser when connecting to our web-app. Deadline for app delivery will be December 19th. This will be a christmass present for our customers. The app must be published under our company manufacturer name. Source code must be provided. English fluency, working microphone and availability for conference call are required.
