iPhone now lets you make WhatsApp your default for messages and calls, here’s how

iPhone users can now get setup so that WhatsApp is their default messaging and calling app.

If your iPhone is updated to iOS 18.2 then the functionality is already available for you right now.

This means that whenever you hit a phone number or call button in a browser, WhatsApp will open. The same applies to messaging from anywhere like Contacts, Maps and beyond.

Apple isn’t saying you have to do this, or stay doing this, but has simply opened up the options so you can have your phone setup personalized to whatever serves you best.

How to default to WhatsApp on iPhone

First up ensure you’re running iOS 18.2. Up to date? Move on.

Next step is to open Settings and then roll on down to the Apps section.

From here you’ll want to go deeper into Default Apps. You should then be met with a list of compatible apps.

Select WhatsApp in both the Messaging and Calling menus.

That’s it. You’re setup so the next time you need to call or text from another part of the iPhone, it’ll send you straight to your WhatsApp setup.

Note it’s listed in beta

While this appears to be available in the latest iOS version, it’s actually noted as a feature for the WhatsApp testflight beta.

The beta is a version of WhatsApp that can be downloaded and used by anyone that wants to try the latest features first. Of course it can mean there are sometimes bugs not quite worked out yet, so this isn’t for everyone.

It appears to work perfectly well with the latest standard WhatsApp beta version on iOS (version 25.8.74 in the App Store). When that applies to all versions of the standard WhatsApp is less clear.

What’s next?

Hopefully this is the start of this new change and we can expect more customization for third party apps as they get added.

Perhaps opening right in Telegram would be nice? Or instead of opening Maps on a location, you’d prefer to go right into your taxi app of choice?

I put Google Gemini on my iPhone. Here’s why I’ll never go back to Siri

The AI frenzy has gripped every smartphone maker in 2025. Unfortunately, not all of it has been as revolutionary as on-stage presentations would have you believe. A few, however, have done a fantastic job with executing practical AI features.

Google is one of those names, and it continues to do so even on iPhones — at the cost of making Siri look like an outdated relic. The latest build of Google’s Gemini app for iPhones puts the AI chatbot everywhere on Apple’s smartphones, from the lock screen to the share sheet.

The iPhone 16e is here now, but is it the iPhone you should buy?

Hand holding iPhone 16e.

It’s decision time, folks. After much hype since it was announced, the iPhone 16e is now available in stores. The phone, which is now Apple’s budget phone, has a lot of great things going for it, assuming you fall into Apple’s demographic for the handset. And yet, if you plan on purchasing a new iPhone right now, there’s possibly a better phone you should buy instead, the iPhone 14.

After Apple announced the iPhone 16e, it became clear that it shares more similarities with the iPhone 14 than with the iPhone SE 3, which many initially believed the rumored “iPhone SE 4” would replace. The iPhone 16e may turn out to be a much better device overall. Consequently, it’s not surprising that the introduction of the iPhone 16e has led to the discontinuation of both the iPhone SE 3 and the iPhone 14.

AI-powered Priority Notifications land on iPhones with iOS 18.4 update

Apple has just released the first beta build of iOS 18.4 update. Even though it is not loaded with new features, it brings a cool new trick called Priority Notifications. Once enabled, the tool will use AI to automatically surface notifications that are deemed important.

”Priority notifications appear at the top of the stack, letting you know what to pay attention to at a glance,” says Apple. The company doesn’t offer any technical detail on how exactly the onboard AI decides which notifications are important and surfaces them.
