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.
