MacSense
Know What's Actually Happening On Your Mac
A plain-English Mac health check — CPU, memory, disk, heat, and network in real language, not raw numbers. One purchase includes MacSense Pro, with sensor-level detail, on up to five Macs.
AppMast is a small independent studio. Several focused apps — for your Mac, your car, your home, your downtime, your device, and your imagination.
Know What's Actually Happening On Your Mac
A plain-English Mac health check — CPU, memory, disk, heat, and network in real language, not raw numbers. One purchase includes MacSense Pro, with sensor-level detail, on up to five Macs.
Every AppMast app is built and maintained by the same small team, which means each one gets sustained attention instead of being shipped once and left to drift.
Designed to keep your data on your own device and, where an app offers sync, in your own iCloud account — not on our servers. We don't sell or share your data with advertisers.
Every AppMast app is sold through Apple's App Store. Buying MacSense on the App Store also unlocks MacSense Pro with sensor-level detail on up to five of your Macs.
The AppMast Lineup
An app joins the lineup only when it solves something we'd actually want solved — on your Mac, iPhone, or iPad.
A Free Mac Text Editor With Real Power Tools
A free, fast text editor for the Mac: syntax highlighting for 17 languages, a command palette, folders with search, code folding, split view, multiple cursors, and a Markdown preview with math and diagrams. No account, no tracking.

Personal Fleet Management
Track maintenance, mileage, leases, and fuel for every vehicle you own. Scan receipts with OCR, get AI service predictions, and keep every document in a digital glove box.

Your iPhone's Complete Diagnostic Dashboard
Real-time vitals, per-core CPU load, battery, thermal, and memory monitoring, plus a full network toolkit — speed test, ping, DNS, traceroute, and more.

Home Management, Done Right
Your home is probably your biggest investment. Dwelling Docs organizes its full history — maintenance, warranties, expenses, and documents — and grades it with a Health Score.

Your Personal Watch Library
Stop scrolling, start watching. Describe your mood and let AI find the perfect movie or show from your streaming services. Log, rate, and track what you watch.

Capture the Echoes, Restore the Balance
An immersive urban-exploration and ghost-hunting action game. Track supernatural Echoes across real-world locations, master skill-based combat, and build a personal index of every entity you capture.
