Making apps that go viral is one of the most exciting challenges in software development today. My name is Blake Anderson, and I’ve built three apps — RizzGPT, Umax, and Cal AI —that each reached millions of downloads and made millions of dollars in just one year. Today, I’ll show you how I came up with these ideas and how you can do the same. This is the first post in a five-part series, where we focus on creating tools and content to help you succeed. Let’s dive into the first step: finding a viral idea.
What is a viral idea?
A viral idea is one that can quickly grow from a simple concept to millions of users. In this series, we’ll focus on single-player utility apps. These are apps that solve problems simply and don’t require complicated backends or social features. Your idea sets the foundation for everything else, so picking the right one is crucial.
For example, RizzGPT wasn’t perfectly executed, but the concept—AI-generated responses for dating—was so compelling it made the app a success. The right idea makes everything easier. So how do you come up with an idea like this? Let’s look at the principles and methods that can guide you.
Principles for viral ideas
Principle #1: Solve Big Problems
People want solutions to the biggest challenges in their lives. Think about Maslow’s hierarchy of needs—problems like health, relationships, and personal improvement have the most impact. Your app doesn’t have to fix everything, but it should help with a major part of the problem.
RizzGPT: Helps people navigate dating.
Umax: Uses AI to improve attractiveness.
Cal AI: Makes calorie tracking simple.
If your app tackles a big need, it’s more likely to go viral.
Principle #2: Keep It Simple
Simplicity is key. If your app’s value can’t be explained in three to four words, it’s probably too complicated. Simple apps are easier to understand, share, and can be turned into content.
RizzGPT: Respond to dating prospects.
Umax: Face analysis.
Cal AI: Photo calorie counter.
A simple concept is more likely to grab attention quickly, especially on fast-paced platforms like TikTok.
Principle #3: "Did You Hear About This?"
Your app should be so unique or useful that people naturally want to talk about it. Ask yourself:
Would someone mention it at a party?
Would they share it in a group chat?
Would they post about it on social media?
For instance, RizzGPT spread through TikTok videos, Umax gained popularity through transformation photos, and Cal AI’s success came from users sharing their meals and calorie counts. If your app doesn’t create these moments, keep refining your idea.
Methods to find viral ideas
Method #1: Look at Social Media
Social media is where trends are born. It’s a goldmine for understanding what people care about and the problems they’re discussing. Here’s how to tap into it:
Use Google Trends to see what’s popular.
Explore Reddit communities to find niche interests.
Check out comment sections on TikTok, Instagram, and other platforms.
For a fresh perspective, create social media accounts with completely different interests. For example, if you’re a 25-year-old into tech, try following content aimed at 35-year-old parents. You’ll discover ideas you might never have noticed.
Method #2: Study the App Store
The App Store is full of inspiration. Download a new app every day and figure out why it works or doesn’t. You can also use tools like Sensor Tower to analyze how well apps are performing in downloads and revenue. Look for gaps in the market. If many apps in a category have failed, like social weightlifting apps, it’s probably best to avoid that space. Instead, focus on problems that haven’t been solved yet.
Method #3: Take a Break
Sometimes the best ideas come when you’re not actively searching for them. Taking a break from screens gives your brain time to process everything you’ve learned. Walks, hikes, or workouts are great for sparking creativity.
For example, I thought of RizzGPT during a walk and Umax during a hike. Giving your mind space to connect ideas can lead to breakthroughs.
Final thoughts
Finding a viral idea is the first step to building a successful app. By solving big problems, keeping things simple, and making something remarkable, you set yourself up for success. Methods like exploring social media, studying the App Store, and taking breaks will help you discover your next big idea.
