Gary Yentin, CEO of App-Promo, gave a presentation on the secrets to becoming a number one app. He discussed the challenges of discovery and monetization in the crowded app marketplace. Yentin also presented data from App-Promo's developer survey showing that experienced developers who stick with their apps long-term are more likely to find success, earning over $500,000 in some cases, compared to new developers. The presentation provided strategies for app store optimization, pre-launch marketing, social media promotion, and paid mobile ads to help apps gain discovery and engagement.
