Put your mug in pairing mode by following your mug manufacturer's instructions, and make sure Bluetooth is on. Open MugBar, tap Scan for mug, and MugBar will find and connect to it. On first launch, allow the Bluetooth permission when prompted, MugBar needs it to talk to your mug.

Sometimes. Some mugs have to be set up and paired once in the manufacturer's own app before any other app can use them, so if your mug is brand new, do that first. Firmware updates also have to go through the manufacturer's app, MugBar can't install them. Once that's done, you can use MugBar day to day; just remember a mug connects to one app at a time, so close the manufacturer's app when you're finished there.

A few things to check:

• Confirm Bluetooth is on and you granted MugBar permission to use it.
• Make sure the mug is charged and in pairing mode, following your mug manufacturer's instructions.
• A mug can only be connected to one app at a time. If the official mug app is open and connected, close it (or disconnect there) so MugBar can connect.
• If the mug is brand new, set it up once in the manufacturer's app first, some mugs need that before any other app can see them.
• Scanning stops automatically after 30 seconds, just tap Scan for mug again to retry.

MugBar is designed to work with the Ember® Mug over Bluetooth. It is an independent app and is not affiliated with Ember Technologies, Inc. Other smart mugs are not currently supported.

iPhone, iPad, and Apple Watch. The watch app is free like the rest of MugBar, and shows the current temperature, the ready-in estimate, your presets, and the LED color. If you do subscribe to Full Access on iPhone, it unlocks on the watch automatically.

In the app, on a Home Screen or Lock Screen widget, on your Apple Watch, and, while your drink is heating or cooling, in a Live Activity on the Lock Screen and in the Dynamic Island.

MugBar watches how fast your drink is actually changing temperature and estimates when it will reach your target. Give it a few readings after you pour, the estimate settles quickly and then counts down. When your mug is holding at target, MugBar says it's ready instead.

Presets are your own named target temperatures (Espresso, Latte, Green tea) each with an icon and a color. Tap one and MugBar sets your mug's target; if you turn on Sync Preset Color to Mug in Settings, the mug's LED ring changes to match. You can apply a preset from the app, from the presets widget, or by asking Siri. Selecting a preset while the mug is away works too, MugBar applies it the next time you connect.

Try “Check my mug”, “Set my mug to 55 degrees”, or “Set my mug to Espresso”. The same actions are available as blocks in the Shortcuts app, so you can build automations, like setting your morning preset when your alarm goes off.

Widgets show the latest reading MugBar received. Open the app once so it can connect to your mug; readings then refresh automatically as your mug reports changes. If a reading looks stale, opening the app will reconnect and bring everything up to date.

Yes. Set the target temperature, apply a preset, change the LED ring color, and rename your mug, all from the app, the widgets, your watch, or Siri. Battery level and charging status are there too.

Free covers live temperature and state, presets and LED color, widgets and Control Center, Live Activity you start yourself, alerts, Siri and Shortcuts, and the full Apple Watch app. MugBar Full Access adds two things: the ready-in countdown, and a Live Activity that starts by itself the moment you pour. It is $1.99 a month or $9.99 a year with a 7-day free trial, covers iPhone, iPad, and Apple Watch together, and can be managed or cancelled anytime in your App Store settings.

No. MugBar uses an efficient push-based Bluetooth connection, it reacts to updates your mug sends rather than constantly polling, so the impact on your device battery is minimal.

Completely. MugBar collects no data, has no account, and no tracking. Everything happens on your device. See the Privacy Policy for details.

MugBar is free on the App Store, for iPhone, iPad, and Apple Watch. Full Access is an optional subscription, and one subscription covers all three.
