This is a newly launched app so we can do compromise with the UI - User Interface. Rest, we need to get in the perfect manner.
Although, I personally, not trust the every app launched in these days because the market is filled with apps that can be harmful to your privacy, even bank fraud can happen too.
There are so many criteria to check the authenticity of the app/company and the advertisement is one of them because we think, they are spending amount.
I just saw the ad of TalkCharge and just tried to use it. I’ve paid Rs.50 to them for recharge on my mother’s vodefone number. The amount was debited for my bank account within seconds but recharge was not done. After half an hour I’ve checked the app and the status was Pending and still is on Pending stage after 24 hours.
I’ve sent the email them as I lost the cashback too and However they’ve reverted in just 3 hours and informed that refund is initiated and will credit your wallet in 72hours while I wanted to back the amount in my bank account, from where it was deducted.
Even, you cannot check the transaction history from the hamburger(three lines) button which is the simplest way but they make it difficult because you have to go on your profile section to see the transaction history.
I cannot say about the other offers yet. I suggest that use this with a little amount first.
