Sensor Data Pro vs Blip Stats

Sensor Data Pro helps you capture high-quality sensor recordings from your iPhone or iPad for testing, field work, and analysis. Use it to record motion, location, microphone level, barometer, and magnetometer data in one session. Add event markers as you record, review sensor charts by type, inspect per-axis values, and export complete session files for downstream analysis. Built for reliable long sessions: - Live preview before recording - Configurable sensor selection and sample rate - Background-aware recording behavior with explicit gap annotations when iOS limits sensors - Session analytics dashboards with min/mean/max and timeline context - CSV and JSON export from persisted recordings Your recordings stay on-device by default.

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.
