The "Старо-Мытищинский Источник. До" mobile application by Banana Technology LLC allows users to conveniently order pure bottled water and various other products offered by the company. Operating since 1993, the app facilitates quick access to high-quality products, sourced from artesian wells registered in the water cadastre of the Kasimov water horizon in the Moscow region.

With a focus on maintaining natural purity and taste, the water undergoes dual filtration water treatment for optimization. The app offers a range of products, including mineral water bottled in 19-liter containers by the professional Italian line "R.Bardi." Stringent quality control measures are in place, overseen by the production laboratory and the Federal Service for Supervision of Consumer Rights Protection and Human Welfare (Rospotrebnadzor).
