Upahar- Black Tiger is a business and productivity app developed by Goldstone Cements Ltd. It is available for Android devices and is free to use.

The main purpose of this app is to register masons in a scheme and allow them to record their purchases and monitor their performance under the scheme. The app provides a login access for the masons, as well as for the TTSM (Technical Sales & Service Manager) and the dealer.

With this app, masons can easily record their purchases and keep track of their progress in the scheme. The TTSM can verify the purchases made by the masons through their login access. The dealer, on the other hand, can monitor the journey of the masons but does not have the ability to take any action.

Overall, Upahar- Black Tiger provides a convenient way for masons to participate in the scheme and for the TTSM and dealer to monitor their activities. It offers a user-friendly interface and smooth performance.
