Ugh, another paid tracking app. The costs for these things really add up, don’t they?
For the guide, your best bet is the official Hoverwatch website. They should have a support or FAQ section with the most up-to-date installation steps directly from the source.
Just for future reference, Google’s ‘Find My Device’ and Apple’s ‘Find My’ are built right into the phones and are totally free for basic location tracking. Might save you a few bucks next time.
By the way, did you manage to find a promo code for it? Always on the lookout for a good deal.
