# System requirements

> The versions of macOS, iOS and iPadOS that Sonto 2.0 needs

Sonto 2.0 needs a recent operating system:

| Platform | Requirement        |
| -------- | ------------------ |
| Mac      | macOS 26 or later  |
| iPhone   | iOS 26 or later    |
| iPad     | iPadOS 26 or later |

Sonto is a native app on both platforms, downloaded from the
[App Store](https://apps.apple.com/us/app/sonto/id6502294348). There's no web version, and no account
to create — see [Account & Pricing](/reference/account-and-pricing).

## If you're on an older system

Sonto 2.0 won't install below these versions, and the App Store won't offer you the update. Nothing is
lost by waiting:

* **Sonto 1.7.x keeps working.** Your existing install carries on as before.
* **Your data is untouched.** It stays on your device and in your iCloud account, in the same shape.

When you update your operating system, the App Store will offer Sonto 2.0 and your data comes across
as it is.

<Info>
  To check what you're running: on Mac, open the `Sonto` menu and choose `About Sonto`. On iPhone, open
  `Settings` → `Help`.

## Availability

The requirement is the same on **Mac** and **iPhone & iPad**: version 26 or later.
