Low-budget startup app ideas include creating a niche marketplace app for freelancers or a subscription-based app that offers daily workouts or meal plans. Another option is a language learning app that leverages peer-to-peer teaching, or a community-based app for local events, hobbies, or skills exchange. Personal finance management tools that help users budget or save can be built with minimal upfront costs. With minimal coding, no-code platforms can help entrepreneurs launch MVPs for validation, allowing them to focus on app marketing and growth without high development costs
