How often does CoinNotch update prices?
By default CoinNotch refreshes prices about once a second, which feels effectively live for watching the market. You can lengthen the interval if you prefer to save battery and network, or want a calmer ticker. Updating pauses while your Mac sleeps and resumes when it wakes.
CoinNotch updates prices about once a second by default. That cadence is fast enough to feel live, you watch the number move as the market moves, without being so aggressive that it wastes resources. For a menu-bar ticker whose whole job is to keep you current at a glance, once a second hits the balance most people want.
You can change it
The interval is not fixed. If you would rather the ticker update less often, to save battery on a laptop, reduce network use, or simply have a calmer display, you can lengthen it in settings. A longer interval still keeps the price current, just refreshed every few seconds instead of every one. The battery guide covers using this to minimize energy use.
Updating also pauses automatically while your Mac is asleep, since there is nothing to show, and picks back up when you wake it. If you ever see a price that looks stuck, that is usually just a momentary connection drop, which the troubleshooting guide addresses.
