The honest read
Watch it free. Own the history for $39.
Clarity is the free live monitor.
Control is the one-time purchase that turns those
live readings into a record you keep. Two steps, one app: watch your
machine for nothing, and buy the memory once, when it earns its place.
Free · Clarity
Everything you need to watch it now
- Free, in full. The complete live readout, with no trial timer and no feature held back for an upgrade.
- Light and quiet. Around 70 MB installed, idling under 1% CPU in the tray, and never writing to your hardware.
- No account, no telemetry. Only a non-reversible licence token and an update check that never installs anything on its own ever leave the machine.
- Honest when it can't read. A value Clarity can't take is shown as unavailable, not a zero standing in for a real measurement.
$39 once · Control
Keep the record, see what changed
- History that survives restarts. Readings are written to disk, so the timeline is still there after a reboot, a crash, or a week away, not wiped when you close the app.
- What a live number hides. 24-hour, 7-day and 30-day views surface a fan slowly losing RPM, drive temperatures creeping up, or a disk filling.
- Answers after the fact. A 3am crash or a mid-game slowdown is gone from a live screen by the time you look. Control still has the timeline.
- One-time $39. No subscription, no account, free updates. Buy it once, keep it.
Clarity proves it in the moment. Control remembers it for you.
Same app, same screen you already know: the upgrade adds memory, it
doesn't change the tool. The full requirements and roadmap live in the
specs; the rules both tiers obey live on the
principles page.
