One job, done properly
An app earns its place in the menu bar by solving a single problem completely. We would rather ship a small tool that never surprises you than a suite you have to learn.
Independent Mac software studio
One line of code can draw an endless maze.
TenPrint Software builds small, fast macOS utilities that do one job properly and then get out of your way. Every app is free to download and free to keep using. Where an app has a Pro tier, you pay for it once.
- Native macOS
- Privacy-first
- Pay once, never monthly
- Signed & notarised
Every app runs entirely on your Mac and ships signed and notarised by Apple. Pro features are free to try for 14 days, and nothing you buy ever renews.

How we build
Four rules that decide what goes into a release, and what stays out.
Your data stays on your Mac
No accounts, no telemetry, no analytics pixels. Settings and layouts live in your own home folder, and the only network traffic is an update check and, for paid apps, a licence check.
Buy once, keep it
Paid apps use a one-time licence with a free trial first. No subscription, no feature that quietly disappears when a billing cycle ends.
Honest release notes
Every version ships with a changelog that says what actually changed, including the parts that are still in progress. Roadmaps are published, not implied.
Where the name comes from
10 PRINT
On a Commodore 64, a single line of BASIC draws a maze that never repeats: 10 PRINT CHR$(205.5+RND(1)); : GOTO 10. Two diagonal characters, chosen at random, endlessly. It is the clearest demonstration we know that a very small program can produce something genuinely useful and genuinely surprising — which is exactly the kind of software we like to make.
The pattern behind this page is generated by that same rule.
10 PRINT CHR$(205.5+RND(1));
