Best AI Apps for iPhone Compared
I have mentioned some of the best AI apps for iPhone that will come in handy for everyday use, and some prove to be a great replacement for Siri, too. But before moving on to the complete list, here’s a quick overview of all the apps, along with their best use cases, limitations, and prices.
Overview of the Best AI Apps for iPhone
There are hundreds of AI apps in the iOS App Store, so sorting the ones that are the best out there is difficult. For that reason, I went out of my way to test each app individually on my primary phone, used them everyday and came up with this list. So take a look at the must-have AI apps for iPhone.
1. ChatGPT
Starting with the obvious, it’s ChatGPT. It’s a must-have app on your iPhone since it can basically help you out with everything and anything your mind wanders to. Have any query, ask ChatGPT, need help writing a mail or a blog, it can help you out. Want someone to talk and listen to you, well, you know the answer by now. And now it even lets you have group chats with your friends too. It can create some amazing pictures, as we have already seen in the Studio Ghibli trend in 2025. Plus, its new GPT 5.2 version is even faster and smarter in generating answers with improved context understanding. So if you have been holding off on getting ChatGPT, this is your open invitation to go ahead and try out ChatGPT, and I bet you won’t be uninstalling it anytime soon. Pricing: Free, Pro plan available at $20/month
2. Perplexity
Perplexity is my most-used app on my iPhone, and it’s simply because it is the best alternative to Siri out there. It is a standalone AI app, so you can use it just like you would use ChatGPT for summaries, research, explanation or brainstorming ideas. But its voice mode allows you to play songs from Apple Music, add events to your Apple Calendar, send emails to your Contacts, and much, much more. This kind of integration is only available on iPhones, and it is also great at understanding natural language. So I don’t have to say monotonous commands like I have to do with Siri, and I can be just myself when talking with Perplexity. It is genuinely one of the best AI assistants I have used on an iPhone, and until Apple sorts out its “intelligent” Siri. Pricing: Free, Pro plan for Individuals starts at $20/month
3. Google Gemini
Google’s Gemini is not just another ChatGPT alternative; it has grown out to be something more than that. Not only has it become an excellent tool for explanations, summaries, and other AI tasks. However, it also has a Gemini Live mode where you can show the AI whatever you are looking at and ask follow-up questions about it in real time. This is extremely helpful if you are stuck in a tricky situation and need some help. I have used it to fix my car, even though I am a complete car noob. It can highlight particular items while in the Live mode, clearly outdoing Apple’s Visual Intelligence features. The Nano Banana Pro model excels at creating amazing images, with utmost details and creativity, even with pretty simple prompts. This is another reason why I have added Gemini, and it can also perform Google Search for you using its dedicated Search AI mode. Pricing: Free, AI Pro plan starts at $19.99/month
4. Otter Transcribe Voice Notes
If you often find yourself taking notes on your iPhone, then Otter is the app for you. It is hands down the best AI note-taking app, which can create transcriptions in real time. So you can record your lecture, meeting, or any other discussion and go through it later. It accurately captures spoken words and slides, records audio, and generates summaries. The app can also share notes with teammates to keep everyone in sync. This AI app for iPhone is also compatible with Microsoft Teams, Google Meet, and Zoom. To ensure convenience and flexibility, the user can import or record audio directly to the app. That’s not all. This free AI app for iPhone offers a ton of exclusive features optimized for iOS. Pricing: Free, Pro plan starts at $16.99/month
5. Replika Virtual AI Companion
Replika is by far the most popular AI companion on iPhone, and for a good reason. It’s a full-scale chatbot that engages users in meaningful conversations and provides companionship. Replika is an AI friend who’s as unique as you are. You might start as an acquaintance, but Replika will soon become your friend and even progress to a lover with the premium subscription. As you chat, Replika slowly learns from your interactions and becomes a personalized AI chatbot. You can fully customize Replika’s avatar across genders and appearances. You can talk about your feelings, emotions, anxiety, victories, lament failures, and discuss anything you wish to share without being judged. This AI app for iPhone can track your mood, calm anxiety, help you with stress management, or even find love for you. In short, this AI app for iOS gives you a safe and judgment-free space to chat. Pricing: Free, Pro Plan starts at $14.99/month
6. Arc Browser
Safari is a good browser, but if you want to take your browsing experience to the next level, then you must try Arc. This AI-powered web browser brings a blend of beautiful design and structured information. You can use its “Browse for me” feature to get quick answers as it will search the web for you, and get you the important details within a second. All shown in a well-summized format. It’s not just that; it can also block ads and trackers. So you can enjoy an ad-free experience no matter which website you visit. If you have Arc installed on your Mac or any other desktop, then it will sync data across devices. This way, you can get back to whatever you were looking up, no matter which device you are on. This is why Arch is one of the best AI apps you can have on your iPhone. Pricing: Free to use
7. Welling AI Weightloss Coach
AI is not all about research and information; it can also help to improve your lifestyle and lose weight. That is why I picked Welling, an AI app for iPhone that features a clean and minimal interface, and uses AI to understand what you eat, count calories, and hit your goals every day. You can have a chat with the built-in AI, share details about your lunch, and ask follow-up questions about your meal and its macros. It will display it all in an easy-to-understand fashion and will provide words of encouragement so you stay motivated on your journey. I am on a weightloss journey too, and Welling has helped me a lot to track my calorie intake. It also syncs with Apple Health, so I can keep count of the exercise I have done and how it is affecting my weight loss. So if your plan is to stay healthy, then you must download this app. Pricing: Free, Paid plan starts at $15/month
8. Grok AI
Grok AI is the unhinged cousin of Google Gemini and ChatGPT, which is why I mentioned it last. It can do web searches, summarize information, and get you real-time data, without any bias. It can swear if you want it to, create unimaginable images that other AI apps wouldn’t even dare to make, and have steamy conversations with its AI companions to satiate your 2 AM fantasies. I had a conversation with Grok’s AI companion Ani, and things went south real quickly. But I thought it deserves to be on the list, because it does the job well. It is quick at collecting and representing information, and has access to the vast X (formerly Twitter) database. This can help it find some lesser-known information you might not be able to find with other chatbots. Pricing: Free, SuperGrok starts at $30/month These were the 10 best AI apps for iPhone that are a must-have. I hope you found this piece useful and that it helped you pick the best AI app for you.
