A hill I'm willing to die on:

Spotify's UI & UX will never be defeated.

With 678+ million users, there's a reason it dominates music apps.

Let me break down why its design is so good (and what you can steal from it): Image
1. The navigation is stupid simple:

• Home
• Search
• Your Library

That's it. NEVER more than 2 taps from anything.

While most apps keep adding useless features to their bottom navigator, @Spotify understood that less is more.
2. The mini-player

It sits at the bottom - always there but never in the way.

The gesture to expand/minimize it feels SO natural you forget it's designed. It just becomes muscle memory.

This is what great UX is about - when you stop noticing it exists.
3. Color adaptation.

The UI subtly changes to match album covers, creating this perfect balance between:

• Looking incredibly cool
• Not burning your eyes
• Still feeling like Spotify

@AppleMusic
tried to copy this but it feels clunky in comparison.
4. Search feature

Instead of just "type what you want" - it's a discovery zone with:

• Trending topics
• Visual genre tiles
• Smart suggestions

It's pretty cool. BUT your searches don't sync across platforms!!! Extremely frustrating.
5. Their recommendations make @AppleMusic look stupid.

But what's brilliant is HOW they present them:

Clean labels like "Popular with listeners of..." whatever podcast you listen to most. Nothing is thrown at you randomly.

Beautiful example of minimalist UI design. Image
6. Neat home screen

• Recents
• Made For 'Denis'
• Discover Weekly

It removes all decision fatigue by serving exactly what you need before you even know you want it.

This is what happens when UX centres around how people actually use things.
7. Lyrics/subtitles integration is super cool:

It syncs perfectly, highlights the current line, and keeps it clean.

This is one of those features that brings me actual joy - and @AppleMusic still hasn't caught up after years of trying.
8. Device switching is MAGIC.

Start on your phone, control from laptop. Move to your TV mid-song.

This "Spotify Connect" makes other apps feel like they're stuck in 2010.

Although generally speaking the desktop UI for Spotify is way worse than mobile - more on that in a bit. Image
9. Every detail feels crafted:

• The pulsing animation that matches the beat
• Queue management that's one swipe away
• Context-aware menus that adapt
• Smooth AF volume slider

These tiny things add up to an experience that just FEELS right.
I will be honest though: their desktop app kinda sucks...

I barely even use it because it feels like a COMPLETELY different product.

Even the search results are different between mobile and desktop with the same account - it's extremely frustrating.

But other than that, @Spotify really wins the game with its thoughtful design when it comes to mobile experience.Image
A lot of apps keep adding features nobody asked for.

@Spotify does the opposite - they constantly remove friction and refine what matters.

It is an awesome example of peak mobile design since it respects platform patterns while still feeling special. Image
I've tried all the others.

Apple Music. YouTube Music. Pandora. Tidal.

None come close to the mobile experience. Not because they're bad, but because Spotify went all-in on FEEL over features.

As I often say: that's the difference between good and exceptional design. Image
My biggest takeaway:

The best UI designs aren't the ones with the most features or trendy visuals - they're the ones that become invisible because they work so damn well.

Craft > features.
Feel > flashiness.

I'm obsessed with design psychology.

After 10 years of building products, I've discovered a UI/UX secret:

Dark Mode makes apps harder to use.

Here's why we're all getting Dark Mode wrong, how to use it properly, and what @Apple knew all along: Image
Here's an unexpected fact:

Studies show dark text on light backgrounds is 26% more readable.

The Nielsen Norman Group found reading speed decreases by nearly 10% with white text on black.

Yet every designer acts like dark mode is the holy grail of UX.
Now here's what blew my mind...

Literally half of the world has astigmatism.

That glow you see on white-on-black text? It’s not in your head. It’s called halation.

The letters blur. Eyes strain. Comprehension drops.

But it looks so premium, right? Image

I'm obsessed with design.

Over the last 6 years, I've analysed every Travel App on the market.

Here are 11 of the best (and worst) Travel Apps & what you can learn from their UI/UX(& the market gaps everyone's missing):

1. @Airbnb Image
THE BEST

These guys get it.

Real-time search that doesn't make you want to punch your screen. Map, pricing, availability - boom, all in one view.

No dead ends. No "sorry, not available" after 10 clicks.

The filters actually feel like filters, not a damn spreadsheet.
Image
2. @Flighty

This app was clearly built by someone who LOVES planes. Like, really loves them.

Shows you everything:

• Your actual aircraft type
• Turbulence predictions
• Weather at arrival

Even has this sick passport screen that makes you feel like James Bond.

I'm a product designer.

I've definitely spent 1000+ hours analyzing tiny UI details.

My current obsession is @Apple's Glassmorphism.

Here's the insane technical breakdown nobody talks about (and how you can use this trend effectively in your products): Image
The OG glassmorphism started as a trend.

Designers threw in 20px blur and 10% white, called it “frosted UI.”

Yes it was pretty, but it sure as hell wasn't the most functional.
Too much contrast, bad layering, zero depth logic.

Then @Apple said: “Let’s fix it.”
Try this:

Open your iPhone. Look at the blur.

Now move something colourful behind it.

The blur CHANGES COLOR. Not just tints - it literally pulls the vibrancy through.

That's not how CSS blur works...

Look at these 2 UIs.

One of them will 100% outperform the other for one reason:

Peak-End Rule.

Here's how this psychological principle works & how to use it in your products: Image
As the name suggests, this rule states that your users don't remember everything about your app.

They only remember two things:

1. The most intense moment (peak)
2. How it Ends

That's it. The rest is forgotten by their brain.

(Credits: @UXChrisNguyen)
What this essentially means is that you can literally have 20 mediocre screens...

But if you nail the peak & end?

Users will still love your product. (not saying you intentionally make it mediocre lol)

Let me show you who's doing this right (and who's f*cking it up): Image

I'm a design addict.

I've tested pretty much every music app on the market — and these 5 are worth studying.

Here's a UI/UX breakdown of the 5 most popular music apps (and which features product designers & founders can steal from them): Image
1. @SPOTIFY:

The Social Media of Music. They turned music into @Instagram.

Wrapped = yearly flex
Shared playlists = social currency
Algorithm = scary good at predicting vibes

But here's what they don't tell you:
Spotify's UI is actually manipulative.

Fun fact: those "Made for You" playlists are pushing artists who pay less royalties.

The shuffle isn't random either. It's designed to keep you hooked.

Still the best UX though. Image

Look at these 2 UIs.

One of them will 100% outperform the other for one reason:

Fitts's Law.

Here's how this psychological principle works & how to use it in your products: Image
Fitts’s Law in 3 seconds:

The closer & bigger the target, the faster & easier it is to hit.

You already know this in your bones. It’s why:

• You miss the “close” button & accidentally open an ad
• You try to tap “save” but hit “delete” instead

(credits: anirudhux)
Apps that nail Fitts’s Law:

1. @Google – Massive search bar. Big buttons. Right in your face. Zero confusion.

2. @Spotify (Desktop) – Right-click menus where your mouse already is. Huge targets. Efficient AF. Image
