Has anyone tried polsia? I tried the product but I was far from impressed... even for non-technical folks, they'd probably be better served with lovable/replit + adhoc chats with claude/chatgpt or different services to help with SEO, Marketing, etc. Their traction is impressive though - assuming the numbers are true, my biggest questions are: 1- what is their user retention like; 2- how much revenue has been generated to users through their apps.
