    Flutter ๐Ÿ“ฑ I launch mobile apps in less than 8 weeks. Recent work includes Card.io (got a deal on Shark Tank), Angel7Real (500k follower fitness content creator app), Odyssey Travel App I see so many app founders waste months and even years launching their apps. Common reasons are: โŒ No clear scope. Founders can't define the first version clearly, keep changing scope, and never get to launch and actually validate the idea. โŒ Working with the wrong developers. If your developer doesn't take an active interest in growing your business, it'll be hard for your app to succeed. Many developers just care about receiving development tasks for you and billing you for the hours worked. Avoid at all costs, you need someone who challenges you and wants you to grow. On top of that, once they launch, they usually never grow. Growing an app isn't luck, it's an array of skills. You have to know how to design a good onboarding, paywalls, tracking metrics, how to a/b test, and much more. If we work together, I won't only build and launch your app, I will also help you grow it. I will take a partnership approach, understand your app, and come up with a plan to grow it together. You can expect me to challenge your ideas a lot, because I really want you to succeed. โœ… P.S.: After our 8-week launch, we can plan new features to work on, and work together long-term to grow your app. ๐Ÿ“ฉ If this sounds interesting to you, send me a message and we'll talk about your idea. Looking forward to hearing from you.
