Best AI note-taking apps for iPhone and Android in 2026

Every roundup of AI note-taking tools ranks the same desktop software and then adds "and there is a mobile app." That sentence is doing an enormous amount of work, and it is usually wrong. The phone versions of these products are not smaller copies of the desktop versions. They are different builds with different capabilities, and on several of them the gap between iOS and Android is larger than the gap between two competing companies. This page is about that gap, because it is the thing that will actually catch you out in a corridor, on a plane, or in a car park after a client meeting.

We have ranked the desktop and meeting-bot versions of these tools in a separate comparison. If you are choosing software for a team that lives in scheduled video calls, read that one. This page assumes the opposite situation: the conversation you most need captured is the one that happens away from your laptop.

What is actually different on a phone

Three constraints shape every product on this list, and none of them exist on a desktop.

The microphone is in your pocket, not in a meeting. A laptop meeting assistant joins a calendar event. A phone has to handle an unscheduled, badly-lit, single-microphone conversation with background noise, which is a materially harder transcription problem than a clean Zoom audio stream.

Connectivity is not guaranteed. This is where most of these products quietly fail, and it is covered in its own section below because it is the single most misunderstood claim in the category.

The two platforms are not one platform. Companies ship iOS first, Android second, and the second one arrives with holes. Granola is the cleanest documented example: the Android app shipped on 1 July 2026, an Apple Watch app followed on 28 July 2026, and the company's own help documentation states that phone call notes are available on iOS only. The Android app does not do it. That is not a bug report, it is the published specification, and it means the correct answer to "is Granola good on mobile" depends entirely on which phone is in your hand.

The offline problem, and the answer almost every roundup misses

A product can honestly say it "works offline" when what it means is that it will hold your audio until the signal comes back. That is a recorder. What most people want when they ask about offline is different: they want the words, on the device, while in airplane mode or a basement or a tunnel.

On current public documentation, the paid tools in this category do not do that. Otter, Fireflies, Rev and Notta can capture audio or manage recordings without a live connection, but their documentation does not describe on-device transcription that completes while disconnected. The processing happens in the cloud when the device reconnects. Notta's mobile recording and transcription explicitly require an internet connection.

That is an uncomfortable finding for a page that also lists paid software, so it is worth being precise about what it does and does not mean. The native apps win on availability and privacy, decisively. They do not win on meeting integration, speaker labelling across a twelve-person call, searchable team archives, CRM sync, or any of the workflow that a company actually buys these products for. If your problem is "I need the words and I have no signal", the answer is free and already installed. If your problem is "my team needs every client call captured, labelled and searchable", it is not.

Platform support at a glance

Everything in this table is read from vendor documentation and pricing pages in October 2026. Where a figure is the vendor's own claim rather than an independent measurement, it is labelled as such.

Otter.ai: the most complete phone app, and the clearest free tier

Otter's mobile apps carry most of what the web product does rather than a cut-down subset: live transcription, speaker identification, AI chat over the transcript, and automatic joining of Zoom, Microsoft Teams and Google Meet calls. Transcripts can be edited live on the device and sync across iOS and Android.

The free Basic plan is 300 minutes a month with a 30 minute ceiling on any single conversation, and it includes the mobile apps and the three main meeting integrations rather than holding them back for paid tiers. Pro is $16.99 per user per month, or $8.33 billed annually, and lifts you to 1,200 minutes a month with a 90 minute per-meeting ceiling. Business is $30 per user per month, or $19.99 annually.

The 30 minute per-conversation cap is the number that decides this for most people on the free plan. It is generous for a standup and useless for an interview, and the monthly allowance is not the constraint you will hit first. A 45 minute client call does not produce a shortened transcript on Basic, it produces a transcript that stops.

What Otter does better than anything else here is behave the same on both platforms. There is no capability on the iPhone build that is missing from the Android one, which sounds like a low bar until you read the rest of this page. If you manage a team on mixed devices and need one answer rather than two, that consistency is worth more than any individual feature.

Granola: the best Apple experience, and a genuinely different product on Android

Granola arrived on mobile late and then moved quickly: iPhone, then Android on 1 July 2026, then an Apple Watch app on 28 July 2026 that starts a note from the wrist. For capturing a walking one-to-one or a coffee conversation, starting a note without taking the phone out is a real advantage rather than a demo feature.

The design philosophy is also different in a way that suits phones. Granola is built around augmenting notes you type yourself rather than dumping a raw transcript on you, which produces something closer to usable meeting notes and further from a wall of text you will never reread.

The asymmetry is the thing to understand before choosing it. Granola's documentation states that phone call notes are iOS only. If your reason for wanting this product is capturing phone calls and you carry an Android device, the published answer today is that it does not do the job. That is worth more than any score we could give it.

Fireflies.ai: strongest for in-person capture inside a team workflow

Fireflies ships iOS and Android apps alongside the desktop app and Chrome extension, and the mobile app is positioned around capturing conversations that were never going to be a calendar invite: recording in-person meetings on the fly, adding Fireflies to a live call, uploading files, searching past notes and managing action items from the phone.

Where Fireflies earns its place on a mobile page specifically is the breadth of capture surface. Between the mobile apps, the desktop app, the Chrome extension and the meeting bot, there are few situations where it simply cannot be in the room, and the phone app is the piece that covers everything a calendar invite does not.

Two caveats that apply across platforms rather than only on mobile. The AI features draw on a credit pool rather than being unlimited within a plan, which is easy to miss when you are evaluating on a free tier. And speaker identification degrades in larger meetings and needs manual correction, which is more annoying on a phone screen than on a laptop.

Notta: the language range, and a free tier that is really a demo

Notta's distinguishing claim is breadth: 58 languages for transcription and translation, with real-time bilingual support, which is more than most of this list and is the reason to choose it if you work across languages. The company's own materials claim 98.86% accuracy; we have not independently measured that and are reporting it as the vendor's figure rather than a result.

The free tier needs reading carefully. It is 120 minutes a month with a three minute cap per recording. A three minute ceiling is shorter than almost any real conversation, so the free plan functions as an evaluation tool rather than something you could quietly rely on. Pro is $8.17 a month and raises the per-recording limit to five hours and the monthly allowance to 1,800 minutes.

⚠️ Notta's mobile recording and transcription require an internet connection. See the offline section above before choosing it for field work.

Rev: the one to pick when accuracy has to survive scrutiny

Rev's differentiator is not the AI, it is the option to escalate to human transcription when a machine transcript is not good enough. That matters for a narrow but real set of uses: legal records, published interviews, anything that may be quoted back at you.

The trade is cost and speed. The free tier is 45 AI minutes a month, and Essentials runs $25.49 per seat per month billed annually, which is the most expensive entry point here. Choose it when the cost of a wrong word is higher than the cost of the subscription, and choose almost anything else when it is not.

The two free apps that belong in this comparison

Every tool above charges a subscription and sends your audio to a server. Both platform owners now ship a note-taking transcriber that does neither, and leaving them out of a mobile comparison would be a serious omission rather than a stylistic choice.

Apple Notes, on iPhone

Apple Notes has recorded audio inside a note since iOS 18 in 2024, with a live transcript alongside the recording and the text searchable as soon as the conversation ends. Transcription covers English, Spanish, Portuguese, Italian, French, German, Japanese, Korean, Simplified Chinese and Traditional Chinese, and the whole process runs on-device, with no audio sent to Apple's servers.

The practical limitation is where the transcript appears in the workflow. On iPhone you generally finish the recording and then request the transcript, rather than watching it build in real time. For a lecture or a long interview that is a minor irritation. For a fast meeting where you want to search back ten seconds while still in the room, it is the difference between useful and not.

Google Recorder, on Pixel

Google's Recorder does free on-device transcription in eight languages, keeps the recording library searchable, and uploads nothing to the cloud. Its advantage over the Apple equivalent is that the transcript appears in real time while you are still recording, which is the behaviour most people assume they are buying when they pay for a transcription app.

The constraint is hardware. This is a Pixel feature rather than an Android feature, so it is not an answer for the broader Android market, and that is the single biggest reason the native option is a clean recommendation on iPhone and a conditional one on Android.

Privacy is a mobile-specific question, not a generic one

On a laptop, "your audio goes to our servers" is a procurement conversation. On a phone it is a different question, because the phone goes places the laptop does not: a hospital corridor, a client's kitchen, a car with a third party in it who did not consent to anything.

The cloud tools on this page process audio off-device by design, and that is not a flaw, it is how they deliver speaker labelling and search across an organisation. But it does mean that the recording of a conversation you had in a sensitive setting now exists on somebody else's infrastructure under somebody else's retention policy. The on-device options are the only ones on this page where that sentence is not true.

⚠️ Recording law is jurisdictional and it is not the app's problem. Consent requirements differ by country and by US state, and some require every party to consent rather than one. The presence of a record button is not permission to use it.

How to choose, in the order the decisions actually matter

1. Do you need words without a signal? If yes, the decision is already made: Apple Notes on iPhone, Google Recorder on Pixel. No paid tool on this page currently clears that bar.
2. Which phone do you carry? This is a larger factor than brand preference. Granola's phone-call capture is iOS only. Google Recorder is Pixel only. Several decisions collapse the moment you answer this.
3. Is the conversation scheduled or ambush? Meeting bots handle calendar events well and corridor conversations badly. In-person capture from the phone app is the feature that matters here, and Fireflies and Otter both have it.
4. Will anyone else read the transcript? If a transcript leaves your own notes and reaches a client, a court or a publication, accuracy stops being a convenience and Rev's human escalation becomes worth its price.
5. How long is a typical recording? Free tiers are capped per recording, not just per month, and the per-recording cap is what you will hit first. Notta's three minutes is the extreme case.

Bottom line

• If you want one app and you carry an iPhone: Granola, for the Watch capture and the phone-call support, with Otter as the fallback if you need a bigger free allowance.
• If you carry an Android device: Otter or Fireflies. Granola's iOS-only phone-call limitation removes the main reason to choose it.
• If you work across languages: Notta, on a paid plan. The free tier's three minute cap makes it unusable for real work.
• If the transcript may be quoted: Rev, and accept the price.
• If you genuinely need words while offline: Apple Notes on iPhone or Google Recorder on Pixel. Both transcribe on-device, both are free, and no paid tool on this page currently matches that on published documentation.
• If the conversation is sensitive: the on-device options are the only ones here where the audio does not reach a third party's servers.

Standards and research behind this page

Platform availability, plan limits, pricing and feature gaps were read from vendor documentation, help centres and pricing pages in October 2026. Dated platform facts (Granola's Android launch of 1 July 2026, its Apple Watch app of 28 July 2026, and its iOS-only phone-call support) come from the vendor's own announcements and help documentation. Accuracy percentages attributed to a vendor are that vendor's published claim and are labelled as such; we did not independently measure them. Vendors change pricing and platform support more often than reviews are refreshed, so check the current figure at the vendor before subscribing.
