v0.2.1-beta — GPU usage, split temperatures, app search & clearer frame-time

[AbiMangalan]

JankMark v0.2.1-beta

A zero-overlay Android performance profiler — read live FPS, frame-time, and
hardware telemetry from your phone over ADB on a clean PC dashboard.

Beta: stable for everyday use, but still gathering feedback. Please file
anything odd under Issues (logs are at Help ▸ Open Log Folder).

✨ Highlights

• Find your game fast — type-to-search the app list, or hit Detect to
  auto-select whatever's currently open on your phone.
• GPU usage on more devices — reads GPU usage without root on more phones;
  where a device blocks a stat, the chart now explains why instead of going blank.
• Per-sensor temperatures — separate CPU / GPU / battery lines; click the °C
  gauge to cycle Max → CPU → GPU → Battery, and hovering names each line.
• Frame time that matches what you see — real on-screen frame interval
  (120 FPS ≈ 8.3 ms, 60 FPS ≈ 16.7 ms) with an Even / Fractional / Uneven
  cadence indicator, and a built-in "?" explaining why a phone's frame time
  naturally steps up and down (it's vsync, not stutter).
• Readable charts — auto-scaling that ignores one-off spikes, plus pan +
  zoom on the report timeline so long sessions stay legible.
• Power, battery, voltage & current live charts, a session library
  (auto-saved, reopenable with full charts), PNG report export, and a
  "?" badge on every metric explaining what it means.

📥 Install

1. Download JankMark_Setup_v0.2.1-beta.exe below.
2. Windows SmartScreen may warn because the build isn't code-signed yet — click
   More info → Run anyway. (Signing is on the roadmap.)
3. Run it. ADB is bundled — no separate setup. On your phone, enable
   Developer Options → USB debugging, connect over USB, and accept the
   authorization prompt.

Requirements: Windows 10/11 · a USB cable · an Android device with USB debugging.

⚠️ Known limitations

• GPU usage is unavailable on some chipsets (e.g. Mali / Pixel) due to vendor
  policy — GPU clock speed still reads, and the app shows a short note explaining
  the gap.
• Connect over USB first. Wi-Fi works once paired, but full Wi-Fi pairing for
  Android 13+ is still being finished — USB is the reliable path for now.
• FPS may not resume after backgrounding the game. If you send the game to the
  background mid-session and return, the FPS meter can stay paused until you stop and
  restart the session. Known issue, fix coming in v0.2.2.
