A beautiful, native system monitor for iPhone and iPad, in 46 languages. View on the App Store
Corynx shows exactly what your iPhone or iPad is doing, in a clean, fast dashboard built entirely in SwiftUI. It tracks CPU load (with per-core detail), the memory breakdown (wired, active, inactive and compressed), storage, live network throughput, battery level and charging state, the system thermal state, and full device, chip and GPU information. Everything is measured on-device using Apple’s public APIs — your metrics never leave your phone.
Free gives you a real monitor: live CPU load with core counts, memory in use, storage, network type and status with the data used this session, battery level and charging state, the thermal state explained in plain language, your device, chip, iOS version and display, the last hour of trends charted, and Home Screen widgets. Live upload and download speed is part of Corynx Pro, along with per-core load, the memory breakdown, the Metal GPU specification, power-flow estimates and the longer trend ranges.
Corynx Pro adds the depth: per-core and performance/efficiency cluster CPU with load averages, the full memory breakdown with pressure, network graphs with per-interface throughput and packet counts, power analysis, GPU and advanced device specs, long-range history (7 days by minute, 90 days by hour) with CSV export, the Lock Screen Live Activity and Dynamic Island, threshold alerts, Siri shortcuts, the fastest 1-second refresh, and no ads.
Pro is a Monthly or Yearly subscription with a free trial for new subscribers, or a one-time Lifetime purchase that never renews. Current pricing is shown on the App Store and inside the app. You can also try any Pro section free for four hours by watching a short video — no purchase, no account.
iOS deliberately does not expose these to third-party apps. There is no public API for battery health or cycle count, an exact temperature in degrees, live GPU utilization, disk I/O rate, or per-app energy use — those are private, system-only measurements. Corynx never invents numbers: it shows the thermal state (Nominal → Critical) that iOS does report, the battery level and charging state, and the GPU specification from Metal. Everything shown is real and measured.
On a real device, yes. In Apple’s Simulator some values reflect the host Mac (for example battery shows “N/A” because a simulator has no battery, and core counts match the Mac). Install on an iPhone or iPad for true device readings.
Open Settings → Corynx Pro inside the app to see your plan, price and renewal date, and to manage or cancel. Subscriptions are billed by Apple and can also be managed in iOS Settings → your Apple Account → Subscriptions. On a new device or after reinstalling, tap Restore Purchases.
Yes — a single banner on the Overview screen, served through Unity LevelPlay mediation, helps keep the app free. It never covers the controls or your metrics. Corynx Pro removes ads entirely. See the Privacy Policy for exactly what ad data is involved and how to control it.
Please email mwsupplylimited@gmail.com with your iOS version, device model, and steps to reproduce. We read every message.
There is a Mac version too. It reads everything iOS will not let an app see — real CPU and GPU temperatures, fan speeds and fan control, battery health and cycle count, SoC power draw, a full process table — and lives in your menu bar. Corynx: System Monitor for Mac.
