Best AI agent apps for iPhone (2026)

The best AI agent app for iPhone depends on the job. For a standing team of agents that each keep one job, on the model you choose, with approval before anything goes out, use Stormi. For one-off tasks inside a chat, ChatGPT agent. For one assistant you text, Poke. For long autonomous projects, Manus. For building workflows from a browser, Lindy or Zapier Agents.

We make Stormi, so weigh that. We've tried to be fair: each section says plainly who should pick something else.

What makes an app an "AI agent" app

A chatbot answers. An AI agent acts: it uses tools (your email, calendar, CRM, a browser), checks the results, and keeps going until the job is done. When comparing, look at:

• What it can touch. Which tools it connects to, and how you sign in.
• What it asks first. Whether it waits for you before sending, paying, or deleting.
• When it runs. Only when you ask, or also on schedules and while your phone is off.
• Which model it uses. One fixed model, or your choice.
• How it fits on a phone. Notifications, widgets, and quick ways to ask.

The short list

Checked November 2026. These products change fast; check each one's site for current details and prices.

1. Stormi: best for a team of agents that keep a job

Stormi gives you a team of bots. Each has a name, one job, and its own model. Your Inbox Manager triages email every morning; your EA preps meetings; Sales Outbound follows up with leads; a Chief of Staff hands work between them, and you can read every thread.

Why it stands out:

• Any model on OpenRouter, chosen per bot: a fast one for triage, a strong one for research.
• Plugins built on MCP, plus any remote MCP server by address.
• Bots run on Stormi's server, phone on or off, with routines on a schedule.
• Every send, payment, deletion, or submission waits for your tap.
• Native iPhone: widgets, Live Activities, Dynamic Island, and the Action button to ask about your screen.
• Free to download; usage by bot and by model.

Pick something else if you need Android or a desktop app, or a tool that has no MCP server yet.

2. ChatGPT agent: best for one-off tasks

ChatGPT's agent mode takes a task, works on a virtual computer with a browser, and reports back. It's strong at research, comparison shopping, and filling in forms, and it's right there if you already pay for ChatGPT.

Pick it if your tasks are occasional and varied. Pick Stormi if your jobs repeat and should run without you starting each one. See Stormi vs ChatGPT agent.

3. Poke: best for an assistant you text

Poke lives in your messages: iMessage, SMS, or Telegram. It connects to your email and calendar and handles requests in the thread, with nothing to install.

Pick it if you want one assistant and never want to open another app. Pick Stormi if you want several specialists, your choice of model, and a full log of every step. See Stormi vs Poke.

4. Manus: best for big autonomous projects

Manus takes a goal ("research the market and build me a report") and works through it on its own cloud computer, often for a long stretch.

Pick it if you want a deliverable from one prompt. Pick Stormi if you want agents that keep an everyday job. See Stormi vs Manus.

5. Lindy: best for building agent workflows

Lindy is a no-code agent builder with lots of templates, mostly used from the web. You can describe an agent or build it from triggers and steps.

Pick it if you want a visual builder for a team. See Stormi vs Lindy.

6. Zapier Agents: best if you already live in Zapier

Zapier Agents act across Zapier's huge app directory, on command or on triggers.

Pick it if you depend on a niche app only Zapier connects. See Stormi vs Zapier Agents.

What about Siri?

Apple Intelligence makes Siri better at understanding you and acting inside apps that support it. It's an assistant for quick requests, not a set of agents that keep a job, run on a schedule, or work in your CRM. Many people use both: Siri for quick asks, agents for the work.
