To build an app like Co-Star, start by choosing who your app is for and how it should sound. Next, build a system that creates a birth chart from a person’s birth date, time, and place. Then add daily readings, short daily alerts, and a way to compare charts with friends. Keep the design clean and simple. Launch a basic version on iPhone and Android first, and earn money through paid plans and paid questions. A basic version costs about $25,000 to $40,000 and takes 3 to 4 months. A full app like Co-Star costs $60,000 to $150,000 or more and takes 6 to 9 months.<\/span><\/p>
