Here is a guide to what apps to build

If you’re reading this, you probably like building apps as much as I do. And until now, I actually just built whatever app came to my mind. And I love it.

However, I value my time more and more, and it is limited, so I want to only build apps from now on, that also have the potential to make money, or “do something good” (But more on that in a future newsletter).

So, but what apps have the potential to make money and are reasonable to be built?

My Golden Criteria:

1. Should Be Used Every Day
   Think about apps people check every morning or use before bed. Frequent usage means better retention, stronger engagement, and, ultimately, a larger user base. For example, a calorie tracker works because users log their meals every day.

2. Should Have Virality Potential
   Social media, leaderboards, or collaboration features can make your app inherently shareable. Think about how Duolingo’s streak sharing motivates people to get their friends involved. Or just one feature in your app that looks amazing and would look great on Tiktok.

3. One Feature Done Well
   Simplicity wins. Users love apps that solve one problem beautifully. For instance, a photo-cleanup app that only helps users delete bad pictures but does it with precision is easier to market and faster to develop than a full-blown photo editor.

Understanding Human Drivers:

Behind every successful app is an understanding of basic human behavior. These are drivers that influence how people act. Apps that tap into these needs have a much higher chance of success:

• Dating: People seek relationships. Dating apps like Tinder thrive on this. Even niche dating apps work well when they address specific groups or interests.

• Making Money: Financial security is a universal need. Platforms like Etsy, Robinhood, and Upwork work because they empower users to generate income or grow their wealth.

• Vanity: The desire to look good and be recognized is powerful. Social media apps like Instagram or beauty enhancement tools like Facetune capitalize on this.

• Family: People want to stay connected with loved ones. And nothing is too expensive for family. Or think of your future kids, you will definitely subscribe to that special kids sleep sound app.

• Addiction: Yes, addiction is a driver. Gaming apps, social media, and even endless scrolling apps (think TikTok or Reddit) rely on this behavior loop to keep users engaged. Or think of quitting something. Countless apps out there that help you with that.

The App Idea Checklist:

When brainstorming app ideas, run them through this checklist. If they don’t tick most of these boxes, it might not be worth pursuing:

1. Does it solve a daily problem or integrate into daily life?

2. Can it grow organically through virality or social sharing?

3. Does it focus on doing one thing exceptionally well?

4. Does it tap into a strong human driver like dating, making money, or family?

5. Would you use this app regularly or recommend it to someone?

6. Is the development timeline realistic for your resources?

Remember: Build apps that are ideally used every day. They should become a habit. That’s how you succeed.
