Some of my earliest memories go back to the late 90s when the Game Boy Color launched. I remember being six or seven years old, walking into a store with my dad to pick up a Game Boy Color and a copy of Pokémon Blue. I spent countless hours playing that Game Boy, and looking back, it played a major role in sparking the tech interest I still carry today. Fast forward to 2026, and mobile gaming has evolved in ways we could not have imagined back then. Touchscreens are incredibly capable, but nothing truly replaces the tactility of real buttons, and most controllers are not portable enough to justify carrying everywhere. So when I saw just how tiny and lightweight the abxylute M4 Snap-On Mobile Controller was, I knew I had to test it for myself. Here is what you should know.

For this part, let’s just focus on the facts. Below this, you can see my actual thoughts on it. But it is amazing just how much they were able to fit into a device you can hold in the palm of your hand. They leverage modularity, MagSafe, Bluetooth, and clicky buttons to give you a seamless mobile gaming experience. Here are the specs:
- Snaps on via MagSafe
- Lightweight at just 55g
- Full controller layout: Dual joysticks, ABXY buttons, D-pad, shoulder buttons, triggers, home button, start, and select
- Magnetic ring detaches from the controller and lets you set up in tabletop mode
- Bluetooth 5.3
- Battery life is rated for 12 hours and charges via USB-C
- Compatible with: iOS, Android, PC, Nintendo Switch, Xbox Cloud Gaming, and emulators.
As you can see above, it checks off a lot of boxes for a mobile controller. It is also a huge added bonus that you can use this with your Nintendo Switch. You also get an adhesive magnetic ring in the packaging if your phone does not have MagSafe already. And you also get a nice lanyard in the box. But now, how was it in actual use?
My experience
The M4 has been an overwhelmingly positive experience, especially for the type of gaming I tend to gravitate toward. I used it primarily with the Delta emulator to play my Pokémon games, and it feels like the controller was made for retro titles. Those older game titles just play better when you have real buttons instead of relying on haptic feedback from your display. I recently was on a few flights, so this was the perfect testing ground for this device. I used it to play the Delta emulator and played some Apple Arcade titles that supported controllers, like NBA 2K and Retro Bowl. The flight was about 3 hours, so I played for basically 2.5 hours straight. I wanted to test the battery, consistent Bluetooth connectivity, and size. The controller is very small, so I wanted to make sure it didn’t cramp my hands. To my delight, it was great. The battery and connectivity had no issues, and the gameplay felt great.
The games I play do not really require much quick twitch or fast action. But if you play a game like Call of Duty or Fortnite, the controller will still be comfortable enough to play for extended periods. From my testing, there is also no latency. Some other notable fun things about this are the modularity and the magnet strength. The magnets on the controller are insanely strong. I think this wins the award for the strongest magnetic attachments for an accessory so far. The modularity piece is great too, and it helps with hand fatigue/strain. You can remove the magnetic ring from the controller, and it unfolds to create a stand for your iPhone. This allows you to play in tabletop mode, which is how I played Retrobowl most of the time. Literally makes it feel like a mini console in your pocket.
One last thing I wanted to call out is that this is pretty much only for landscape-oriented games, which covers most situations you would want to use a controller. Most vertically oriented games rely on swiping and touching the screen. I enjoyed this because the Delta emulator removed the on-screen controllers when it realized it had physical controls attached. So the experience was much more immersive and premium.
Pricing & availbility
The abxylute M4 Snap-On Mobile Controller is available today from abxylute’s website. It comes in six colors: Phantom Black, NGC Indigo, Atomic Purple (my favorite), Cosmic Orange (the one I used), Halo Green (only color on back order), and Retro White. Abxylute is selling these for $49, which I think is a great price for everything they can do. I also like how they are leaning into the nostalgia and retro looks with the colors and materials. Also, to reiterate, this works as a console controller for the Switch as well!
Final thoughts
If you grew up on physical controllers and still appreciate that traditional gaming feel, the abxylute M4 is an easy recommendation. It strips away the friction of mobile gaming, adds back the tactile experience many of us miss, and does it in a package that’s small enough to carry everywhere. The best part is the modularity. You can keep it attached when not in use if you like, or completely remove it and put it in your pocket. The design and ergonomics are great as well. It is not trying to replace a true game controller; instead, it focuses on portability, simplicity, and nostalgia.
What do you think of this controller? Is it worth it to you for $49? Do you game on your iPhone enough to warrant a dedicated controller like this? Let’s discuss down below!
