Loan apps are sucking demons... their greed is not of this world. How can you charge somebody 25% to 30% in one month? That is ritual money from a very strong juju. I no blame them sha, na our government and the economy I blame.
I no sabi much about loan apps, but if this na the range of interest wey dem dey charge, then it is quite high, but the thing is, dem no force anybody to take loans from them. They are ready to release their funds, they fix the interest rate and people decide for themselves if na something wey dem go fit pay back.
I notice say too many Nigerians dey default on their loans from these loan apps, na as you post their interest rate now, na wetin make me understand why people dey refuse to pay back, but nonetheless, there is no justification for a loan defaulter, read the terms and service before taking the loan and if you'll not be able to pay, then don't take it.
