From idea to impact
Build Your Vision with Developers Who Believe in It
After spending months refining your app idea, you still have one question: who should you trust to build it?
You’re looking for app developers who understand why your idea is important. The ideal team builds your app because they believe in it.
You want people who have done this before, and who have answers to the questions that you don’t yet know to ask. This isn’t a search for the cheapest vendor. It’s the beginning of a lasting partnership.
Every decision at this stage matters. You need experts who know how to make your app a success without experimenting on your business.
We’ve been there, and we’ve helped dozens of clients face the same challenges you are no facing. In fact, we started Twin Sun to help good people build excellent software.
Confidently Building Together
Our first conversation will be about your business, your goals, and your vision for the future. Once we understand where your business is headed, we form a dedicated team to help you get there. You see a working app in your hands at the very first week. You can review our progress as often as you like. We welcome your feedback at every step. You know the people building your app, and their good work shows you how much they care about your business. We work with you every day until your app is a success.
Together, we plan a goal-based budget for creating a successful app. We discuss our progress every week to ensure we stay on target. We stand by the quality of our work. If we discover issues during internal testing, beta testing, or the first 30 days after your first App Store release, we fix them for free.
Reaching Your Goals Within Your Budget
Launching When You Like
We have launched apps with valuable user experiences in as little as one month. Your app will always be in releasable state. We launch in the App Store when you decide it’s ready. App Store updates occur as frequently as you wish. You are always in control of your product’s release schedule.
