Vizo: Battery Monitor & Widget

Which charger works best with your iPhone? Vizo helps you compare real charging sessions, estimate battery life and explore battery usage with clear charts and widgets.

Start with free battery tools. Unlock charger comparisons and advanced insights with Vizo Pro, available as a one-time purchase. No subscription.

COMPARE YOUR CHARGERS WITH VIZO PRO

Give your chargers a name, assign your recorded charges and see how your everyday setups compare:
- Average charging speed
- Observed 20-80% charging performance
- Consistency across comparable sessions
- Charger history and trends

See which charger leads, how many usable sessions support the result and how confident the comparison is. Share a text summary of your comparison.

ESTIMATE YOUR REMAINING BATTERY TIME

See how long your battery may last based on available readings and observed usage. Check estimates for reaching lower battery levels and understand when a result relies on recent or previous usage.

RECORD AND REVIEW YOUR CHARGES

Use the guided Shortcuts setup to record battery levels when you connect and disconnect your charger. Review starting and ending levels, battery gained, duration and average charging speed.

During charging, Vizo can estimate time to targets up to 80% once enough data is available. Pro adds charging curves and deeper session analysis.

EXPLORE YOUR BATTERY HISTORY

Zoom into your battery level chart and explore changes over time. Switch between hourly consumption and daily activity to see the battery use and recharging Vizo has observed. Pro extends battery history to 30 days.

Missing readings stay visible as gaps, not invented measurements. Exact readings and approximate observations are clearly distinguished.

ADD BATTERY WIDGETS

Bring useful battery information to your Home Screen: battery level, estimated remaining time, charging activity, a 24-hour trend, hourly consumption and daily battery activity.

STAY INFORMED WITH BATTERY ALERTS

Enable charging-session summaries and alerts for low estimated battery time. Vizo Pro adds unusual-drain alerts, overnight-drain alerts, daily or weekly summaries and custom low-battery-time thresholds.

VIZO PRO: ONE PURCHASE, NO SUBSCRIPTION

Unlock charger comparisons, advanced charging analysis, 30-day battery history, full charger history and trends, unlimited charger profiles and advanced alerts.

GOOD TO KNOW

Shortcuts setup enables precise charging start/end records; charger names and session assignments are managed by you. Estimates, widgets and alerts depend on available readings and iOS refresh opportunities. Vizo does not speed up or stop charging and is not an electrical power meter.
