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 LOVE design psychology.

@Apple, @NotionHQ, and @Family all exploit the same psychological loophole to dominate their competition.

It's called Jakob's Law.

Once you understand it, you'll never look at product design the same way again 🧵
Jakob's Law is simple:

Users bring expectations from EVERY other app they've used before yours.

This means people prefer your product to work the SAME WAY as products they already know.

Break this, and you're training users from scratch. Good luck with that.
Jakob's Law in practice:

When your design matches users' expectations, it feels "intuitive."

When you break it, users get that "WTF" feeling.

Suddenly they have to think about your interface instead of just using it.

Design isn't art. It's psychology.

I design apps for a living.

I've spent 6+ years using every FinTech app on the market.

Here are 9 of the best (and worst) FinTech apps & what you can learn from their UI/UX:

1. @RevolutApp
@RevolutApp is becoming an "everything app" beyond just banking.

I literally booked a hotel last weekend for €6 for two nights (plus a free massage) using Revolut points.

It has a clean, consistent UI that doesn't try to do too much at once.
I've been a customer since 2016. They have:

• REAL-TIME support (crucial for anything involving money)
• Transaction "pots" that auto-save 1% from purchases
• Pending transaction trackers
• Bill splitting feature

Pretty solid.

I'm an Apple fanboy.

But I admit some of their apps suck.

Here's my brutally honest take on the 9 most popular @Apple apps (as a product designer):

1. Apple Maps
Apple maps went from being the app everyone laughed at to a genuinely great experience - BUT only in the US.

It sucks in most other places.

It also still misses some of Google Maps' best features like Street View and business info details.
2. Apple Wallet

This app is unmatched.

It's so intuitive and I find it almost weird when someone doesn't use Apple Pay. I spent an hour looking for my physical card when I needed cash because I'm so used to just tapping my phone.

The animation is 🤌

I'm starting a design war.

Here are 10 times Apple's UI obliterated Android's:

1. Superior Notifications
iOS Notifications have a beautiful bounce animation that feels weighted.

Notice how the notifications don't just appear - they settle in with a satisfying "plop" feeling.

Android is functional, sure. But not fluid and haptic. It lacks the "feel."
2. Dynamic Island

When Android phones were copying @Apple's notch back in 2017, Apple said: "We’re not doing notches anymore. We’re building an island. Let’s see you copy that."

They wanted people to instantly recognize - "Oh, that’s an iPhone."

It was genius. Image

I'm obsessed with design psychology.

Here are 9 psychological tricks your favorite apps use to keep you addicted:

1) Skeleton Loaders
Those gray loading "skeletons" replace content before it loads - because it makes the waiting time feel shorter.

Movement creates the illusion of progress when nothing's happening.

Ex: LinkedIn & FaceBook. Image
Image
2) Color Psychology

Notification badges are red for a reason. Red triggers urgency and attention in our brains.

Blue creates feelings of trust and security.

Ex: Banking apps and Facebook built their entire brand on the trust signals of blue. Image

I design apps for a living.

But I've never seen ANYTHING like the @notboring apps.

They're redefining what "good design" means with physics, weight & movement.

Let me show you how they make their apps feel alive (and what designers & founders can steal from them): 🧵 Image
Before I break down each app...

The thing I love about @notboring is they're not crazy revolutionary in terms of features.

But they took basic apps (calculator, weather, timer) and just made them FEEL amazing.

Same functions - but completely different experience.
How @notboring apps are built differently:

• Created with Apple's SceneKit (game engine)
• 3D models crafted in Blender
• Physics-based animations
• Custom sound design
• Haptic feedback

Traditional app development can't achieve this feel...
