Battery Insights

Battery Insights turns your smart ring's battery readings into the numbers the official app never shows you: real drain rates, charging habits, lifetime cycles and how your endurance is trending over time.

DASHBOARD

Current level, estimated remaining time and predicted next charge at a glance — plus hourly and daily drain, observed full runtime, average charge speed, and a 24-hour history chart.

CHARGING HABITS

Every charge session is detected automatically: gain, duration and %/min speed, with full charges flagged. Lifetime stats show sessions, equivalent cycles and how you actually treat the battery.

ENDURANCE TREND

Compares your earliest near-full-to-low runs with your latest ones, using strict matching rules so the trend only appears once there is enough comparable data. No guesswork, no fake precision.

LOW-BATTERY ALERTS

One local notification per discharge when the ring drops below your threshold (5–50%, default 20%). It re-arms after you charge back up.

HISTORY YOU CONTROL

Battery level over 24 hours, 7 days or 30 days, plus the full reading list. Log readings manually with one tap, or connect your ring account to sync automatically in the background.

PRIVATE BY DESIGN

Everything is stored on your device — there is no account with us and no server of ours holding your data. Analytics is strictly opt-in and off by default. Export every reading as JSON, or delete everything, from Settings.

NO ADS

No ad SDK, no ad slots, no tracking identifiers for advertising. The app is free; an optional "buy me a coffee" donation is the only purchase, and it unlocks nothing but a thank-you badge.

Built in a strict black-and-white theme for people who like their data plain.
