Tandem Player Lifetime Updates, One Time Payment.
The free build plays. A Viewer key adds the tools that shape how it moves and the tools that change the motion rather than play it. A Full key adds the generator, which makes a motion file from the video itself.
No subscription, and updates stay free for as long as you use Tandem, no matter when you bought your key. Windows 10 / 11, 64-bit, or macOS 12+ on any Mac.
Already have a key? Every key sold before October 23, 2026 is a Viewer key, and it keeps everything it unlocked. To add the generator, upgrade to Full for $35, the difference. You enter your Viewer key at checkout and get a Full key back; the Viewer key is retired once the Full key is sent.
Pay by card, Apple Pay or Google Pay, or with Litecoin. Your key arrives the moment payment clears (for Litecoin, after a few network confirmations): it is on the order page and in your email. There is no installer: you unzip a folder and run it.
Not sure yet? The free build is the same download. Paste a key into it whenever you want the rest.
Free, Viewer and Full
On the screen
Everything needed to watch a video with a device moving in time with it is free. Viewer buys control over how it moves, and the shelf the library sits on — every theme and Safety Mode. Full adds the generator.

|---|---|---|---|
| Library — multi-folder, search, filters, thumbnails | yes | yes | yes |
| Playback and device sync — every connection type | yes | yes | yes |

In the headset
Headset playback is not a paid feature. The free headset mode is a viewer — everything needed to put it on, watch, and sit where you want to sit. A Viewer key adds the ability to change that motion from inside it.
| Free | Viewer | Full | |
|---|---|---|---|
| Play / pause, stop, next | yes | yes | yes |
| Recenter | yes | yes | yes |
| Viewing distance — stepper and hold-to-push | yes | yes | yes |
| Seek bar, −10s / +10s | yes | yes | yes |
| Browse page, Random | yes | yes | yes |
| Volume, mute | yes | yes | yes |
| Exit to Editor / Library | yes | yes | yes |
| Depth, Top reach, Bottom reach | same caps as the screen | yes | yes |
| Presets — apply, clear | locked | yes | yes |
| Edit page — headset auto-range, save | locked | yes | yes |
| Script lookup from a source you add, for a scene with no motion file | no | yes | yes |
A Viewer key does not include the generator; a Full key is the Viewer key plus it. Locked rows stay drawn and answering. A row that has quietly vanished teaches nobody what they are missing, and a dead one just reads as a fault.
What a key is
One key, one PC, and it moves
- Unlocking asks the licence server. If it cannot be reached, the key unlocks anyway for seven days, and Tandem asks again each time it starts until the server answers
- After that the unlock is a file on your own PC, good for a year, and needs no internet
- One check a launch — about half a minute in — asks whether the key has moved to another PC, and quietly collects the next year when the file is inside its last two months. What that request carries
- Moving to a new PC means pasting the same key there. Nothing to deactivate first. The first move is free; after that a move waits 30 days
- Two PCs in use at once need two keys. You can buy more than one in an order
- A Viewer key upgrades to Full for the difference in price. The old key stops working once the new one is sent
- Free updates, forever — no matter which version you bought at
Refunds
If it does not work, say so
Licence keys are delivered instantly, and all sales are final once your key has been sent. If Tandem does not work on your machine, contact me first — I will help you get it running, and if it genuinely cannot work I will refund you.
If a key that has never been activated does not work, email me your order ID and I will replace it. A key that refuses after activation is almost always the one-PC binding rather than the key itself, and that takes about a second to clear from my side — you re-paste the key you already have.
