## What is VoltLog?

VoltLog is a field tool for FPV pilots who use LiPo, LiHV, and Li-ion battery packs without smart battery electronics.

After a flight, log the pack voltage and VoltLog shows the safety status of each battery on a clear, color-coded dashboard. The goal is simple: know which packs are safe for storage, which need charging, and which should not be left full for too long.

Built for FPV battery routines:

- Track battery packs with name, brand, cell count, capacity, chemistry, and cycle count
- Log voltage per cell with a large custom keypad
- See STORAGE, CHARGED, FULL, FULL RISK, DISCHARGED, and CRITICAL states at a glance
- Open full cycle history for every pack
- Set global and per-battery alert timing
- Use local notifications for risky full packs and low-voltage reminders
- Work offline-first with local Drift storage
- Secure or switch accounts with Supabase Auth when you want cloud-backed data

VoltLog is not a charger, cell checker, or battery management system. It is a practical logbook for pilots who already measure voltage and want a faster way to keep track of many packs.

Designed for the field, not a desk:

- High-contrast dark dashboard
- Large battery tiles
- Fast voltage entry without the system keyboard
- Battery archive for retired packs
- English and Polish interface

If your FPV case has more packs than memory can reliably track, VoltLog gives you one place to see what needs attention before battery degradation becomes expensive.

- Simplified the profile screen.
  - Removed technical session details: user ID, anonymous status, and account type.

  - Moved first name editing higher, closer to the profile details.

### 0.0.19 — 2026-06-03

Automatic Selection: A battery is now always automatically selected by default if the list is not empty.

Instant Focus: When you add a new battery, the app immediately highlights and selects it for you.

UI Enhancement: The active, selected battery now features a thicker, more visible border.

Stability Fix: Prevented an issue where users could enter voltage values without having a battery pack selected.

### 0.0.18 — 2026-05-21

No release notes.
