It’s not every day that we get to say a screen protector absolutely dominates every single test we throw at it—but that’s exactly what happened with the Flolab NanoArmor 6. We’ve tested dozens of tempered glass protectors over the years, and while we already knew Flolab made great stuff, the Flolab NanoArmor 6 blew our expectations out of the water. With updated testing methods and side-by-side comparisons, this one came out on top in nearly every category. Let’s dig into why this is probably the best iPhone screen protector you can get in 2025.
| Pros | Cons |
|---|---|
| Best-in-class optical clarity (0.93) | Single pack pricing is high |
| Exceptional glare reduction (40%) | Small cutout at the top |
| Strong oleophobic coating with minimal residue | |
| Excellent edge and impact strength | |
| Best installation kit and fit compatibility |
Design
Design-wise, the Flolab NanoArmor 6 ranks #2 overall in our testing—but it’s a very close second. Flolab uses double-tempered aluminosilicate glass, which our crack testing confirmed to be the real deal. This thing is large—in fact, it offers 94.61% coverage on the front face of the iPhone (average is 93.07%), and 100.29% display coverage. It’s the only black-edged screen protector we’ve tested that doesn’t cut into any pixels.
Most screen protectors come with a basic install kit, but Flolab goes the extra mile. Their frame includes foam padding, and they throw in a huge dust sticker—simple but super effective. They even include a polarized test film so you can check your sunglasses against the screen.
Our only gripe? A small cutout at the top prevents it from being a perfect 10.
Performance
This is where the Flolab NanoArmor 6 really flexes. It ranked #1 for performance across the board. Optical clarity scored 0.93 (average is 0.9), which is the best we’ve recorded—yep, this is the one we always reference in our other reviews. It also cuts glare by 40% thanks to an anti-reflective coating. For context, the next closest protector came in at around 17%, and the average was actually worse than the naked screen.
The oleophobic coating? Also top-tier. Oil droplets took 61.57 seconds to travel 6cm at a 30° incline (average is 44s), and the trail left behind was almost non-existent. So not only does your screen stay cleaner, but it also feels super smooth.
Protection
Flolab doesn’t just win on looks and feel—it’s also a tank. It ranked #1 for protection in our tests. Scratched at a solid 7H on the Mohs scale, and edge strength came in at 147.2N (average is 86.18N). Only one other screen protector had stronger edges. In the sharp impact test, it withstood 313.26N—well above the 271.44N average—and only three products scored higher, none of which had edges this tough.
Value
Here’s the deal: at $39.95 for a single pack, the Flolab NanoArmor 6 isn’t cheap. But when we look at the full chart of the Top 20 screen protectors we’ve tested, Flolab didn’t just squeeze into the lead—it crushed it. It includes extras like blue light filtering, and honestly, with the performance you’re getting, the price feels justified. You’re paying for the best.
Verdict
If you’re after the best iPhone screen protector for 2025, the Flolab NanoArmor 6 is it. It’s the only one that’s nailed every test category—design, performance, and protection—without any real compromises. The clarity and glare reduction are unmatched, the edge strength is next-level, and the install process is idiot-proof (in a good way). It’s rare that we don’t have a single negative thing to say about a product, but here we are.
From reviewers who actually test this stuff and don’t rely on sponsored hype—this is the one we’d personally use on our iPhones.
