Choosing between the Neo Smartpen N2 and M1 can be a challenge, especially when both offer smart handwriting features designed to digitize your notes seamlessly. Let’s dive deep into the differences in design, functionality, battery life, compatibility, and more—so you can decide which smartpen truly fits your needs.
Design and Build
Neo Smartpen N2

The N2 features a triangular body made from aluminum and stainless steel, giving it a premium feel and enhanced durability. It’s slightly larger and heavier than the M1, measuring about 156.5mm in length and weighing around 22 grams. This gives it a sturdy grip, but some users might find it a bit bulky for long writing sessions.
Neo Smartpen M1

The M1 has a more minimalist, rounded design made from hard plastic (fiberglass). It’s lighter—just 17.4 grams—and a bit shorter at 149.6mm. It feels more like a regular pen, which makes it ideal for those who prefer traditional pen ergonomics.
Verdict: If you want a luxurious, solid feel, go for the N2. But if comfort and portability are top priorities, the M1 is the better pick.

- Android 5.0 or later
- iOS 8.1 or later
