About

Battery Duo shows the battery of your Apple Watch and your iPhone at the same time on the watch face – one glance at your wrist is enough. 3 IN 1 – SAVES SPACE The outer ring shows the iPhone's battery, the inner ring the watch's, and the middle shows weekday and date. Three pieces of information in just one complication – so the other slots on your watch face stay free for what else matters to you. THIS IS HOW IT LOOKS • Double ring with date: iPhone outside, watch inside (or the other way around), weekday and date in the middle • Numbers with symbol, numbers only, rings or bars – you choose • Colored by level: green, yellow, red – limits freely adjustable • Lightning bolt while charging, gray display when a value is outdated ALWAYS UP TO DATE • The watch regularly fetches the iPhone's battery level in the background • Turbo update: a ready-made Shortcut and a few automations send the value each time you use your iPhone, charge it, or the battery drops below a 5% step NOTIFICATIONS • Watch or iPhone fully charged – time to unplug • Low battery – time to charge • Watch battery as a number on the iPhone app icon EASY TO SET UP • All settings on iPhone and watch – changes apply immediately on both • Complication for round, rectangular and corner slots as well as the text line UNLOCKING Yearly subscription: 3 days free, then €9.99 per year, renews automatically, cancel anytime. Or a one-time purchase of €29.99 for good, no subscription. Both unlock all features: iPhone battery on the watch and in the complication, notifications when full and nearly empty, battery number on the app icon, Turbo update. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://bertramplischke.github.io/batterie-duo/datenschutz.html Note: iOS reports battery levels to apps in 5% steps; small differences from the status bar are normal. Made with love in Bräunrode.

What's New in Battery Duo

1.1

November 1, 2026

New in 1.1 • Battery Duo is now also available in English: app, watch, complication and notifications. • The Shortcut "Battery Duo" is still labeled in German. The guide in the app explains what it does. • Settings now has an "Also by Bertram Plischke" section pointing to Rogr, my push-to-talk app for Apple Watch. A tap shows the App Store page right inside Battery Duo. Nothing is shared in the process. Known and unchanged • iOS reports battery levels to apps only in 5% steps. The display can therefore differ from the status bar by a few percent. • In Low Power Mode, iOS pauses background refresh. The iPhone battery level then reaches your watch only when you open the app or the Shortcut runs. Something missing or not working? Write to me via "Send Feedback" in Settings.
