Questions
When will my Dialtone ship?
We build in batches of 500 and ship them in the order reservations came in. Batch 1 ships in March 2027, and each batch after that ships about a month later. Your reservation number and batch are shown as soon as you reserve.
Do I pay anything to reserve?
No. Reserving is free and takes your email, country, and finish. When your batch is ready we ask you to confirm and pay. If you change your mind, ignore that message and your spot goes to the next person.
Can I change my finish after reserving?
Yes. Before your batch ships we ask you to confirm everything, including the finish. Changing it keeps your place in line.
Does it need an app?
Out of the box it works as a standard volume knob with play and pause, no install needed. The free companion app adds the focus timer, lights, app shortcuts, and lets you choose what each turn and press does.
Which computers does it work with?
macOS 13 or later, Windows 10 or later, and current Linux desktops (Ubuntu 22.04, Fedora 39, or anything that runs an AppImage). It connects over USB-C or Bluetooth 5.3.
How long does the battery last, and can I replace it?
About three weeks per charge with normal use. The battery sits on a plug-in connector under five Torx screws, and the driver is in the box. Replacement batteries will be sold at cost.
Can it control my lights?
Yes, through the companion app. It works with lights on Matter and with Home Assistant. Turn to dim, press to switch on or off.
Can I use it with more than one computer?
It remembers up to three computers. Hold the dial down for two seconds to move to the next one; the e-ink label shows which one is active.
Where do you ship?
The countries in the reservation form: most of Europe, the United States, Canada, Australia, New Zealand, Japan, South Korea, Singapore, Hong Kong, and Taiwan. Prices include import duties everywhere we ship.
What does the warranty cover?
Two years on every part, from the knurled cap to the rubber foot. After that we keep selling spare parts at cost for at least seven years, with repair guides for each one.
