Given your situation, it's essential to start small and locally. Engage with community groups, local events, and volunteer organizations where your target users are likely to be. Use platforms like Nextdoor to reach local communities. Personal stories and word-of-mouth can be powerful, so ask friends and family for help sharing your app. Consider partnering with local influencers, even if they're micro-influencers, to spread the word. This grassroots approach can help you get your first 10 users and gather valuable feedback.
