Pop-Hub

Pop-Hub Limited · Hong Kong

Small, careful apps
for Mac and iPhone.

Two of them, made and maintained by one developer. No accounts, no subscriptions, no analytics SDKs — just tools that do one thing and keep doing it.

Sharp Lynx

macOS

CPU, GPU, memory and temperatures live in your menu bar, plus a full dashboard with per-core detail. Formerly SystemPal.

Free · macOS 14 or later

IQ Test

iPhone & iPad

Two full-length tests, a certificate with your score, and your global ranking. On the App Store since 2010.

Free, with a Pro version

How we build

Quiet software.

Sharp Lynx measures your Mac and shows you the numbers. It has no network code at all — it is sandboxed with network access switched off, so it cannot phone home even in principle. Nothing is collected, so there is nothing to leak.

Questions or bug reports go straight to a person: support@pop-hub.com
