Blip is a featherlight system monitor that lives in your menu bar. One click shows everything happening inside your Mac — CPU load, memory pressure, disk activity, network speeds, and more. No clutter, no subscriptions, no bloat. Why people love Blip: Blip makes everything your Mac is doing visible without getting in the way. It polls every two seconds, uses about 42 MB of memory, and weighs roughly 2 MB on disk. Most system monitors use 200+ MB and ship features you'll never touch. What you get: CPU — Total usage bar in your menu bar. Click for per-core utilization, user/system/idle split, load averages, and P-core and E-core counts. Memory — Usage percentage at a glance. Drill into total RAM, active/wired/compressed/app breakdown, swap, and memory pressure. Network — Live connectivity in the menu bar. Tap for up/download speeds, bandwidth since boot, interfaces with IPs, VPN detection (Tailscale, WireGuard), tap-to-reveal public IP, and a history chart. Disk — Every mounted volume with space used and free, real-time read/write speeds, data transferred since boot, and a live I/O history chart.* GPU — Apple Silicon GPU utilization, renderer name, core count, and a historical chart. Optional menu bar readout.* Battery — Charge, health, cycle count, temperature, time remaining, charging status, power source, and condition.* Fans & Thermals — RPM per fan with min/max ranges, plus CPU and GPU temperatures read straight from the SMC. Shows "fanless Mac" gracefully on MacBook Air.* Top Processes — Top 5 by CPU and memory, with app icons and delta-based measurements that match Activity Monitor.* System — Mac model, macOS version, uptime, thermal state, and Blip's own memory footprint so you can verify it stays tiny. Metrics marked * need hardware-level access. Install the free Blip Helper companion app to unlock them, at github.com/blaineam/blip. Test and automate: Speed tests built in — benchmark any mounted drive with uncached sequential write/read plus random-read IOPS, and measure network throughput against OpenSpeedTest's public server or your own. Run a live traceroute (MTR) with per-hop loss and latency, mapped hop by hop. Shortcuts support — Get System Metric exposes 37 live metrics as chainable numbers. Run speed tests, start or stop a traceroute, open the Traceroute Map, and read or change Blip's settings — from the Shortcuts app. Designed to stay out of your way: Two menu bar layouts, horizontal or stacked. Hover any row for a live sub-panel. Customizable colors: category, monochrome, or your own — plus label toggles, optional colorization at high usage, and launch at login. Built right: Written in Swift with strict concurrency and zero external dependencies. Apple Silicon native, notarized by Apple. Blip Bench: Measure what your machine can actually do. Blip Bench scores CPU (single and all cores), memory bandwidth and latency, GPU, and Neural Engine throughput in fixed reference units — one scale shared by every Mac, iPhone, and iPad running Blip. The full profile adds a sustained phase showing how much performance thermal limits take back, against live fan and temperature data. Now on iPhone and iPad: Blip Stats 2.0 is one free app across your Mac, iPhone, and iPad. The iOS app brings live device cards with drill-in details, Blip Bench, dual-curve speed tests with idle vs under-load latency and per-activity connection grades, ping and traceroute with an offline GeoIP hop map, disk speed tests, Home Screen widgets, Shortcuts, and one-file stats snapshots.
VoltLog
Read full descriptionHide full description
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.

Verdict
The clearest difference is in-app purchases: Blip Stats at none against VoltLog's 3. Blip Stats also leads on device support (3 vs 1). VoltLog's advantage is update cadence (every 10 days vs every 3 weeks). On price, ads and iOS requirement there is nothing between them.
