I've tried PiggyVest for months now and honestly it's solid for saving money and investing small small. The app interface is smooth, no wahala opening it or moving money around, and knowing my money is actually growing there keeps me motivated unlike when I used to just keep cash. My only gripe sha is the withdrawal process takes longer than it should, like sometimes I need access to my money quick and waiting days is frustrating when other apps sha let you pull out almost immediately. Overall it's reliable though and I recommend it for serious savers like myself.
