KUMA Timer is a single application — the same binary and the same code on every platform. A licence unlocks time, not features: every install begins with a 30-day Full trial, with every capability available from day one. When the trial ends, you either enter a £8 licence and remain on Full for life, or revert to Lite (free, core countdown) and continue at no cost.
Free forever · macOS · Windows
Activates automatically once your 30-day Full trial ends.

KUMA Timer is an independent project, not a venture-backed business. It exists because I kept needing a countdown timer that genuinely held up on show nights — and every alternative was either a $30-per-month subscription, a roll of the dice on the App Store, or an abandoned GitHub repository from 2019.
The £8 covers the running costs that keep this legitimate — an Apple Developer subscription, an Azure code-signing certificate, a relay server and Stripe fees — with a small margin left over. No outside investment, no growth targets, no "Pro" tier waiting in the wings.
Please don't expect enterprise-grade support or a four-hour SLA. You will receive direct email replies from the person who wrote the code, typically within a day or two. If that doesn't suit your operation, Lite remains free, with no obligation.
Price shown is net of VAT. UK buyers pay £8 + 20% UK VAT = £9.60 at checkout. Buyers outside the UK pay £8 flat — no VAT or sales tax is added; you're responsible for any local tax or duty due in your own jurisdiction. Payment processed by Stripe. See Terms & Conditions, Privacy Policy, Refund Policy.
One Full licence works on macOS, Windows or Raspberry Pi — the installer auto-detects the platform and the licence code is platform-neutral. Move between machines any time via the deregister portal.
KUMA Timer keeps working, but switches to the Lite feature set: 10 presets / 10 cues, MM:SS only, and without SMS, NDI, LTC, KUMA Live and Raspberry Pi kiosk mode. The web admin and Bitfocus Companion keep working for the core timer controls (start / pause / reset, presets, cues); Full-only actions such as SMS are declined. You can activate a Full licence any time from the About screen to unlock everything again — including any presets and cues you already have.
No. The trial starts automatically when you first launch the app — no account, no card, no email. It's tied to the machine's hardware ID so it can't be reset by reinstalling.
Yes — the £8 Full licence is platform-neutral. It's bound to one machine at a time, but you can freely switch between Mac, Windows and Pi by deregistering on one and registering on the other via the deregister portal. No extra purchase.
Yes. Visit the deregister portal (or use About → Deregister inside the app), enter your code, and click Deregister. Then install KUMA Timer on the new machine and enter the same code. There's no limit on how often you do this.
Email support@kumatimer.app with the email address you used at checkout and we'll resend it.
Yes. Within 14 days of purchase, before you've activated the code, you're entitled to a full refund with no questions asked — that's your statutory right under the UK Consumer Contracts Regulations 2013 (and the equivalent EU distance-selling rules). After activation that statutory right no longer applies (you've started using digital content), but if the app isn't working on your machine we'll fix the bug or refund anyway. And if you simply changed your mind after activating — email us. We usually say yes. See the refund policy for the full picture.
Yes. The Pi kiosk is driven entirely through the web admin panel, which is a Full-tier feature. You can still use the 30-day Full trial on Pi before deciding.
Yes. Vizrt has confirmed in writing that a KUMA Pi install qualifies for the royalty-free NDI® Standard SDK path — it's software you install yourself on your own Pi, using full-bandwidth NDI with no HX/Advanced SDK features. NDI® output on Pi works the same as on macOS and Windows. Raspberry Pi also has OMT output — a royalty-free, NDI-compatible alternative (see the OMT documentation) — pick whichever your receiver supports.
Full licences are verified with our server at launch (and every 7 days after, with a 14-day offline grace period). Lite and Trial do not contact the server. See the privacy policy for what we collect and how long we keep it.
Yes. Churches, theatres, conferences, broadcast studios — all use KUMA Timer commercially. The Full licence is per-machine, not per-event or per-seat.
