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, and no network entitlement — the macOS sandbox denies the capability outright, 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
