Tapzo is to be shut down by 31st October, 2018. It was launched with a target to bring many apps (35+) under one roof that includes cabs, recharge, food, shopping deals, bill payments, news and etc. Tapzo was earlier known as HelpChat when I personally started using it.
Tapzo, the biggest app aggregator in the country had tie up with Ola, Uber, Mobikwik, freecharge, nearby, Zomato, Swiggy, hindusthan times, airtel money, Cleartrip, bookmyshow, billdesk, redbus, mysmartprice and others.
Tapzo had sent a mail to its users on 2nd of September regarding its shutting down.
Interestingly there was market news that Amazon to buy out Tapzo on August end.
Update: Tapzo was actually acquired by Amazon Pay soon after Tapzo's announcement of shutting down services.
