## What is Cell?

Your battery. Actually understood.

Cell is a personal battery assistant for your rechargeable devices. Track earbuds, a watch, phone, tablet, laptop, power bank or stylus in one colorful home. Start with a first estimate; useful measurements gradually refine your own device's consumption rate and remaining-use forecast.

MAKE EVERY READING COUNT
Add a device, record its percentage and enter how long you actually used it. Compare recorded levels with the forecast, see the confidence level and explore 7-day, 30-day or all-time history. Active-use estimates and elapsed-time estimates are clearly distinguished.

READ AUTOMATICALLY WHERE SUPPORTED
Track this iPhone or iPad automatically. The Apple Watch companion reads its own battery and shares it with the paired iPhone. Supported Bluetooth accessories can send real readings. The optional Cell Mac helper shares your Mac's battery over Bluetooth. Other devices, including AirPods whose battery isn't exposed through public APIs, use quick manual check-ins.

YOUR ALERTS. YOUR RULES.
Choose up to three battery thresholds for each device. Optional local check-in, charge and learning notifications respect quiet hours and limit repeated alerts. Home Screen and Lock Screen widgets show your latest recorded readings.

APPLE PENCIL, ACROSS YOUR DEVICES
Read on the paired iPad, then optionally share the latest measurement to your iPhone through the same Apple Account's iCloud. Automatic reading depends on Pencil and iPadOS support; if unavailable, manually enter the percentage from Apple's Batteries widget on the iPad.

MADE PERSONAL
A short tour and step-by-step guide help you get started. Follow your system language or choose from 10 languages in Settings. Export or delete your data whenever you like. No Cell account, ads, tracking or analytics. The developer cannot access your measurements.

Battery predictions are approximate. Automatic readings, iCloud delivery and widget refresh depend on hardware support and Apple's execution rules. Battery health appears only when valid data is available, with its source identified.

Your devices, together
Choose iCloud sync during setup or in Settings to share all your tracked devices, battery history and per-device alerts between iPhone and iPad using the same Apple Account. Enable iCloud Drive on both. Connections and app preferences stay local; delivery is managed by Apple.

## Version history (last 2 releases)

### 1.0.5 — 2026-10-30

Cell now builds its layout from the display it is actually given.

• A foldable iPhone works on the cover screen and on the inner screen, including when the window resizes while a page is open.
• Device cards, insight panels, metrics and history reflow into two columns on wide screens instead of stretching.
• Devices keeps the list beside the detail pane whenever there is room for both, and pushes the detail screen otherwise.
• Home pairs the low-battery nudge with your forecast so the important panel is not pushed below the fold.
• Text-heavy screens keep a comfortable line length on wide displays.
• iPhone now supports landscape as well as portrait.

Existing iPhone and iPad layouts are unchanged, and your devices, history and settings are untouched.

### 1.0.4 — 2026-10-10

No release notes.
