Giving out Equity of your company is tricky. Equity should not be given freely and not to everybody in your company. If you are giving an Equity, then vesting is the key, with a cliff of at least 1 year. I would avoid giving equity to people that you don't know, especially, to developers whom you will yet get to know. Partner and give Equity only to your trusted friends, and colleagues, whom you really know and trust. Hire developers/contractors. Use Upwork as a great resource. You can find a great talent there. If you don't have money to hire a freelancer (developer), use your Entrepreneurial skills to create another revenue stream, or find a job, bootstrap the first simple beta version to see whether people want your app in the first place.
