It took me 1 year, then 1 week, then 1 day

How long it took me to build an app: - 1 year in 2017 - 1 week in 2023 - 1 day in 2026 We live in the best time in the entire history of tech.

Marc Lou@marclou · Jan 27, 2026From app idea to App Store in 24 hours. I wanted to try Claude Clode, so I asked it to analyze my web analytics SaaS @DataFast_ and build a read-only app for iOS & Android. 4 hours later, MVP was ready. I spent 2 hours filling out all the app store paperwork. Android was approved the same day. Apple took a bit longer. The app 100% vibe coded. I didn't write a single line of code. Building startups now feels like a video game. I just dream while AI turns it into something real.
