Is purchasing points from an authorized agent to activate a counter that yields monthly profits perpetually considered usury? And does collecting free points and activating the counter without monetary payment raise a Sharia concern?

What is mentioned in the question is not enough to conceive the reality of the application, but the stated amount involves a clear prohibition, which is obtaining a fixed, guaranteed monthly profit for life, in exchange for paying a lump sum to activate the meter. This is not free from the meaning of gambling, with its elements of uncertainty (gharar) and ignorance (jahalah), or usury (riba), because the participant is at risk of profit and loss, and this is the meaning of usury. If it is established that the method of the application's operation and making profit from it is unlawful, then it is impermissible to share its link, or invite people to it, or profit from that; because prohibited benefits are not met with compensations. Many profit-making applications are based on deception and fraud. Signs of this include exaggerated profits that are not yielded by conventional types of trade. People are lured by such profits to collect direct subscriptions or induce them to promote and spread the application. From these subscriptions, the illusory profits are paid, until the number of new subscribers falls below the amount that covers the profits, at which point the deception and fraud become apparent.
