Right before I left on my vacation I worked hard throughout the night to try and get my app ready for its first testers. I knew that in the next 3 weeks I wouldn't be able to do much aside from reaching out to people. Even though my app is quite niche I didn't think it would be this hard just to get people to try out the app.
In my mind a fresh new Reddit, instagram and TikTok account would be a good start but if anything it holds the process of reaching out back. I underestimated the power an already established reach has. Even if most people in that reach are not your target audience, they are connected to potential users and that gives you a solid starting point.
It was a little bit of a hurdle to get over the fact that people I know will know what Im doing but maybe all in all that ain't a bad thing.
If anyone is interested in a running app and its development feel free to reach out.
