After months of work, i've built a fully functioning fitness app, specifically for intermediate to advanced lifters training for strength and hypotrophy. I built it after my own struggles with trying multiple apps and none of them being sufficient to meet my requirements. After hundreds of hours of work, i'm very confident what i've built is a solid, advanced and insane product. But I have no idea how to market my app, or get my first 100 users. Could someone help me with how I should proceed to get my first 100 users.
