Build Features That Users Love

If you have ever worked on a product roadmap, you know the struggle.

Will users care about this feature? 😬

As an engineer, I can tell you that building features people love isn’t about throwing in fancy tech or quirky ideas and hoping for the best. It’s about understanding what users really need and then delivering it in a way that makes them say:

This is exactly what I wanted! 😍

Think of it like making chai (or coffee, if that’s your thing). You have got to balance the ingredients just right. Too much sugar → it’s undrinkable; too little → it’s bland.

The same goes for features: they need the functionality, usability and a little spark of joy (not you vaasavi 😜). Oh and don’t forget, there’s no magical chai recipe that works for everyone. You have to experiment, taste and adjust.

In the world of product development, the recipe looks like this: decide, build, test, launch and repeat...

Decide 🧐

Every successful feature starts with understanding your users.
What bugs them?
What tiny, everyday annoyances are they begging you to solve?
Surveys, interviews, analytics — use all the tools you can to dig deep into their world. And when you’ve got a million ideas, don’t get distracted. Prioritize the ones that will make the biggest difference.

Your mantra here? Impact over fluff :)

Build 🛠️

Here’s where the engineering fun begins. Start with an MVP.
Yes, because even the first version should feel like something worth showing off.

Don’t aim for a shiny, all-singing, all-dancing feature right out of the gate.
Solve the core problem first, then leave room to grow.

Test 🧪

Think your feature is done?
Haha! Testing is where the real learning happens.

Roll it out to a small group, get their feedback and watch how they actually use it. Just letting you know, they won’t use it exactly how you imagined. That’s okay. Tweak it. Iterate. Rinse and repeat.

Launch 🚀

Time to shine! But don’t just quietly release it — celebrate it! Use emails, in-app banners, or even a cheeky social media post to let users know why this feature is awesome.
Make them feel like this was built just for them (because well it was).

Repeat 🔄

Here’s the catch: you are never really done. After launch, track how people are using the feature. Look at the data. Read their feedback. Figure out what’s working and what’s not and then improve it.
Think of it as a never-ending cycle of awesomeness.

Okay, now enough theory.

Let’s look at some real-world examples of companies that nailed it. These are stories of features that started as ideas, went through the messy process of creation and came out the other side as user favourites 🌟.

1. Duolingo’s Streak Feature 🦉

The Problem: Learning a new language is hard, and people often lose motivation after just a few days.

The Solution: Duolingo introduced streaks: a gamified way to reward daily practice. Each day you learn, your streak grows. Miss a day? It’s gone. (unless you use a streak freeze)

How They Built It: The team realized users needed something to keep them coming back. Streaks tapped into a simple principle: people love consistency and hate breaking a winning streak. Early testing showed users were devastated when they lost their streaks, so Duolingo added streak freezes. The result? Users stayed motivated without feeling punished.

Impact: Streaks turned Duolingo into a daily habit for millions. It’s so popular that users brag about their streaks on social media. Free marketing, anyone?

2. Slack’s “Do Not Disturb” Mode 😴

The Problem: Notifications were driving users crazy, interrupting their focus and causing stress.

The Solution: Slack added a Do Not Disturb mode, letting users pause notifications when they needed quiet time.

How They Built It: Slack started by talking to users who were overwhelmed by constant pings. They built a simple, intuitive way to snooze notifications, with options for recurring schedules. Early testers loved it, and Slack fine-tuned it based on their feedback.

Impact: Do Not Disturb became a lifesaver for users juggling collaboration and deep work. It’s now one of Slack’s most-loved features, proving that sometimes, less noise is more.

3. Airbnb’s Experiences 🏡

The Problem: Travelers didn’t just want a place to stay, they wanted authentic, local experiences.

The Solution: Airbnb launched Experiences, a platform for booking unique activities hosted by locals. Think pasta-making in Italy or surfing lessons in California.

How They Built It: Airbnb started by asking travelers what they wanted most. They piloted the feature in a few cities, collected feedback and refined it. They focused on making it easy for hosts to sign up and for users to book activities seamlessly.

Impact: Experiences turned Airbnb into more than a lodging app. It became a go-to travel platform, attracting a new audience and creating memorable trips for millions.

4. Spotify’s Discover Weekly 🎶

The Problem: Finding new music is overwhelming. Users wanted personalized recommendations without the hassle.

The Solution: Spotify created Discover Weekly, a playlist updated every Monday with tracks tailored just for you.

How They Built It: Using ML, Spotify analyzed your listening habits and matched them with others who share similar tastes. They tested the feature with small groups, refining the balance between familiar favorites and surprising discoveries. And to keep users hooked, they made the playlist refresh every week.

Impact: Discover Weekly became an instant hit. Users loved waking up on Mondays to a fresh batch of songs. It drove engagement, made Spotify feel esstential and turned Mondays into something to look forward to :)

Conclusion 💭

Building features users love is a mix of understanding their needs, experimenting, and improving constantly. The above success stories show what’s possible when you combine empathy with innovation.

So what’s your next big idea? The world’s waiting for it.
