In general, it is not recommendable to adquire debt unless it is necessary.
I have seen some of those apps, specially I have seen Xiaomi's credit app called "Mi Credit", according what I have read it is popular in India (one's of Xiaomi's most important markets).
I am not familiarized with the interest of these apps and whether they are predatory or not, as a rule of thumb, credit is supposed to be a tool for emergency expenses but unfortunately I am aware that there are people in both developed and developing countries that put themselves in a position of increasing debt risking their credit scored and personal finances.
If possible, if you want to borrow money, go to your nearest friends or relatives first because they won't be putting high interest on your loan. As taking loans could bring risks, but in times right now, taking loans has already been a norm especially if you need rush money due to some unforeseen, emergency events. However, be more cautious enrolling in some loan apps online as they can be source of scams or whatsoever. Its better to go to established lending companies as they can be reliable than to try loan apps that are total strangers to you.
