Linux · every app, natively
Linux isn’t the port.
It’s a first-class build.
Five of our apps run natively on Linux — the same features, the same one-time price, the same day. No subscription, no account, no telemetry, and nothing that phones home. Your files stay in folders you control.
Built for Linux, not translated to it
Plenty of software treats Linux as the version that ships late, ships broken, or ships never. We take a different view — and it costs you nothing extra.
Three formats, two architectures
- AppImage — runs on most distributions, no install needed
- .deb — Debian, Ubuntu & derivatives
- .rpm — Fedora, RHEL & openSUSE
- Intel/AMD x86_64 and ARM arm64 builds of each
- Every release ships a
SHA256SUMSfile
The same price as everywhere else
- One-time purchase — no subscription, ever
- Linux is not priced as a premium or a discount
- Sold direct through our own store
- No account to create, no licence server to check in with
- Your purchase never expires and never stops working
Genuinely offline
- No telemetry, no analytics, no “anonymous” pings
- Works with the network cable out
- Your data lives in plain files or an open SQLite database
- Back it up with the same tools you already use
- Nothing to migrate if you distro-hop
Pick your app
Every one is a one-time purchase, sold direct. Buying gets you all three formats and both architectures.
| App | What it does | Formats | Linux price | |
|---|---|---|---|---|
| WillisMD Pro | Markdown workspace — Custom Style Editor, knowledge graph, export | .deb · .rpm · AppImage | $9.99 | Buy |
| WillisGSD | GTD task manager — capture, clarify, Kanban, weekly review | .deb · .rpm · AppImage | $9.99 | Buy |
| CardLoom | Flashcards & study — nine study modes, spaced repetition, test plans | .deb · .rpm · AppImage | $9.99 | Buy |
| WillisLogger | Ham radio logbook — live lookup, POTA & contest modes, ADIF/Cabrillo | .deb · .rpm · AppImage | $29.99 | Buy |
| WillisTP | Teleprompter — markdown scripts, mirror modes, OBS/Zoom overlay | .deb · .rpm · AppImage | $3.99 | Buy |
| WillisSDR | FlexRadio SDR client — panadapter, waterfall, multi-slice receive | .deb · .rpm · AppImage | $79.99 | Coming soon |
Prices are one-time, per platform. Buying on Linux does not include the Apple, Windows or Android builds — we don’t offer a cross-platform bundle, because verifying one would mean knowing who you are.
Three ways in
Pick whichever suits your distribution. All three are the same application.
Runs almost anywhere
No installation and no root. Mark it executable and run it:
chmod +x <file>.AppImage./<file>.AppImage
Debian & Ubuntu
Installs through your package manager, with menu entries and updates handled the usual way:
sudo apt install ./<file>.deb
Fedora, RHEL & openSUSE
The same, for rpm-based distributions:
sudo dnf install ./<file>.rpm
Check what you downloaded
Every release includes a SHA256SUMS file. Confirm your download before installing:
sha256sum -c SHA256SUMS
Before you buy
Which architecture do I need?
- Most desktops and laptops are x86_64
- Raspberry Pi, Ampere and Apple-silicon VMs are arm64
- Run
uname -mif you are unsure
Is it in my distro’s repository?
- Not today — downloads come direct from us
- That keeps releases identical across distributions
- The
.deband.rpmstill register with your package manager
Do I need an account?
- No. There is nothing to sign up for
- No licence server, no activation, no check-in
- The app never contacts us — it cannot be switched off remotely
What if I reinstall or switch distro?
- Reinstall as often as you like on machines you own
- Your data is plain files or SQLite — copy it across
- Get in touch if you lose your download link

Five apps built for Linux, sold once, with nothing phoning home. If something does not work on your distribution, tell us — we would rather fix it than have you work around it.
