# Use CallTuv on Any Device

> The web dialer, iOS app, Android app, and Chrome extension all share one account and one balance - here's what each is best at.

**TL;DR:** CallTuv works in your computer's browser, the iPhone and Android apps, and a Chrome extension - one account, one balance, everything in sync.

CallTuv runs everywhere you do. The interfaces differ slightly between web and mobile, but the capabilities are the same - and because everything is tied to your account, your balance, contacts, caller ID, and call history stay in sync across all of them.

## Web dialer

Open [calltuv.com](https://calltuv.com) in Chrome, Edge, Safari, or Firefox on any computer - nothing to install. It's a full [browser-based phone dialer](https://calltuv.com/web-phone-dialer) that turns [any laptop into a phone](https://calltuv.com/call-from-laptop), and the dashboard gives you the dialer plus full pages for **Balance**, **History**, **Contacts**, and **Team Settings**. The web is also where you top up by card and manage [auto top-up](/help/4573082-auto-top-up-never-run-out-of-credit) and [billing details](/help/2085461-invoices-receipts-and-vat-details).

See [How to Make a Call with CallTuv](/help/5273948-how-to-make-a-call-with-calltuv) for the calling walkthrough.

## iOS and Android apps

- [CallTuv for iOS](https://apps.apple.com/us/app/calltuv-cheap-worldwide-calls/id6764273865)
- [CallTuv for Android](https://play.google.com/store/apps/details?id=com.calltuv.app)

The app has tabs for **Call**, **Recents**, **Contacts**, **Team**, and **Settings**. Calls travel over Wi-Fi or mobile data, so you can call abroad without a local SIM or roaming plan. Top-ups on mobile go through App Store / Google Play in-app purchases - see [How to Top Up Your Balance](/help/8412937-how-to-top-up-your-balance).

## Chrome extension

The [CallTuv Chrome extension](https://calltuv.com/chrome-extension) adds click-to-call to your browser: phone numbers on websites become clickable and dial instantly in CallTuv. Handy if you call numbers from CRMs, directories, or listings all day.

## Everything stays in sync

Whatever device you use:

- **One balance** - shared across web, mobile, and extension (and with your [team](/help/6027384-how-teams-and-shared-balance-work)).
- **One call history** - a call made on your phone shows up in the web dashboard too.
- **One caller ID setting** - verify your number once and it applies everywhere. See [Verify Your Own Number as Caller ID](/help/8927354-verify-your-own-number-as-caller-id).
- **One contact list** - including contacts shared with your team.

Sign in on a new device with the same email, Google, or Apple account and you're exactly where you left off - see [Ways to Sign In to CallTuv](/help/7391824-ways-to-sign-in-to-calltuv).
