Risk: Moderate

Starting a side hustle with mobile app templates can be risky for beginners with limited funds. There is a potential to lose money on template purchases, development costs, and marketing without a guarantee of returns. Beginners might also invest significant time and energy into learning app development and customization. Online reviews mention cases of beginners spending money on templates but failing to generate profits. Setup costs range from $100 to $500, and it could take around 2 weeks to start seeing profits, if successful. I'd rate the risk a 2 out of 5 because there is a significant chance of losing money and time, especially for those new to app development and entrepreneurship.
