VoltLog vs PowrSync

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.

PowrSync keeps you on top of the battery life of every device that matters to you. Pair a phone or tablet in seconds by scanning a QR code, then see its exact battery level and charging status right from your own device — no cables, no guesswork, no more "my phone died" surprises. Once paired, readings stay current on their own. When a paired device's battery changes, or it's plugged in or unplugged, your device is updated right away. Need an instant check? Request a fresh reading on demand and get the latest charge level within seconds. Stay informed without lifting a finger. Turn on smart alerts to be notified the moment a paired device runs low, finishes charging, or goes quiet — PowrSync flags any device that hasn't reported in over 24 hours so you're never left wondering. And the built-in 24-hour history graph shows how each device's battery has trended through the day, so a quick look tells you the whole story. PowrSync is built to be private and lightweight. There are no third-party analytics and no ad trackers — only the minimum needed to run the service (your email and a device identifier). You can delete your account and all associated data at any time, directly from Settings. Key features: - Pair devices instantly with a secure, single-use QR code - Real-time battery level and charging status for every paired device - On-demand refresh — pull the latest reading whenever you want - Smart alerts for low battery, full charge, and offline devices - 24-hour battery history graph for every paired device - Clean, dark interface designed for a quick glance - Privacy-first: no ad trackers, no third-party analytics - Full in-app account and data deletion Great for keeping an eye on a child's iPad, a family member's phone, a spare device, or your own second phone.
