Banani DOHS is a residents' association app for Android and iPhone — pay a service charge without an account, report an issue straight to DOHS security, find the medical directory and see who to call for a community hall. It is the only thing on this page you can put on your own phone rather than take our word for.
Eight screens from the current Android release build.
