OFFO is a free Android application developed by FarPost LLC that helps residents of apartment buildings in Vladivostok and Khabarovsk to collect and send readings of water and electricity meters to settlement organizations. The app also warns users in a few days about the approach of the billing period.

One of the main features of OFFO is its convenient setup of water and electricity meters, which allows users to store the entered data in the application and see the history of readings. Additionally, the app sends the testimony over the Internet, and if for some reason it was not possible, the testimony will be sent via SMS (if possible, the service provider). The app also sends indications for hot water (Vladivostok) to both the Far Eastern Energy Department and VladVTS (water disposal).

Overall, OFFO is a useful app for residents in Vladivostok and Khabarovsk who receive receipts directly from resource-supplying organizations and want to easily collect and send readings of water and electricity meters to settlement organizations.
