Can you really build an app with AI in a weekend?

Can you really build an app with AI in a weekend? If you've been watching the Instagram and Facebook reels, it's easy to get that impression. Type in your idea, watch it come together, and you're on your way.

I've implemented AI to help develop apps. It helps move things along, and I'm excited about what we're building. But just one app has already taken weeks and hundreds of hours of my time. And we're still working on it.

I'm working on this full time. Someone fitting it around a job might have five to ten hours a week. Using a 40-hour week as a benchmark, they'd need roughly four to eight times as many weeks to put in the same hours. That's a comparison of available time, not a prediction of how long their app will take. But it's worth considering before expecting to finish one over a few weekends.

That's the part I wish those reels spent more time showing.

We've gone through hundreds of prompts, with screenshots and recordings to explain what needs fixing. Some changes happen quickly. Others take repeated attempts, including going back over things I thought we'd already settled.

One recent example was an animation. When I touched a piece on the screen, its shadow appeared, disappeared, and then the piece lifted. That little interruption looked like a glitch. I took screenshots and pointed out the step that needed to go. Getting that scene to feel right took hours of testing and adjustments. All that work went into a brief movement someone using the app should find natural.

AI could make the change. I still had to notice the problem and explain it.

There are decisions like that throughout development. A notification works, but covers something the person needs to see. An animation is faster, but looks jerky. A design looks great until you try using it on a phone.

The AI makes mistakes too. Sometimes it only partly follows an instruction or changes a detail we'd already approved. I've had to remind it what to keep and ask it to verify what it says is finished.

Passing code checks and building an app are useful progress. I still need to know whether that exact version works on the phone. I'm the one asking people to try it, so I need an accurate account of where we are.

My communication has caused problems as well. During one sound discussion, I meant that I liked two separate effects. My wording made it sound as though I wanted the same effect used twice. The AI took it that way, and I had to stop and clarify.

I knew what I meant. I hadn't explained it clearly.

As the work grew, we had to improve how we organized it. Decisions were spread across conversations. Approved work needed to reach the right version of the app. We began preparing handoff files so a new thread could pick up the work without losing earlier decisions.

We also tried AI agents. One couldn't review an image because it couldn't access the file another agent had created. Even getting the tools to work together took attention.

Then there's preparing to release it through Apple and Google. We've had to work through their requirements and submission procedures, licensing and permissions, privacy disclosures, and questions about patents and trademarks. Legal notices and personal liability need attention too. Researching requirements, checking permissions, and preparing the documents all take time. That work is part of the weeks and hundreds of hours I'm talking about. AI helps organize it, but I still need to verify requirements and get qualified legal advice where needed. A disclaimer alone doesn't settle those issues.

If you're considering building an app this way, be prepared to stay involved. You'll need to test it yourself, explain what's wrong, and make decisions you didn't know were part of the job. Some days you'll be figuring out what happened to the thing that worked yesterday.

Our apps are still in development and testing. AI has helped us move faster. Weeks and hundreds of hours into one app, I can also tell you that getting it right takes far more work than a short reel can show.

If you have an app idea and want help getting started, or need someone to help develop it, that's something we can discuss. At Vitality Driven, we offer consultation and app creation services. We can help you work through your idea, define what it needs to do, and plan the next steps. Discuss your app idea with us.
