What is Firmware? (And How It’s Different from App Updates)
Firmware is the software that runs inside your physical device — such as PeekSmith, Atom, SB Watch, or Quantum. It controls the device’s behavior: the screen, buttons, Bluetooth connection, vibration, and other hardware functions.
This is not the same as an app update.
- An app update upgrades the mobile app you use on your phone or tablet (like the PeekSmith app, Atom Remote app, or Quantum app).
- A firmware update upgrades the internal system of the physical product.
Why Firmware Updates Matter
Firmware updates can:
- Fix bugs and glitches.
- Improve Bluetooth stability and connection reliability.
- Add new features and enhancements.
- Optimize battery life and performance.
- Improve compatibility with apps, iOS, Android, and other connected devices.
When to Update (and When Not To)
✅ Update if:
- A new feature is released that you want to use.
- The update fixes issues that affect you.
- Support has recommended an update to solve a problem.
🚫 Avoid updating if:
- You have an important performance within a few hours.
- Everything is working perfectly for your current needs.
