Food logging can be done in a few ways, including searching a database, scanning barcodes, or using AI-based camera analysis. Simpler items like eggs and fruit are identified well, but complex meals can be frustrating due to lighting and AI limitations.
The flashiest comparison revolves around the Glyph interface - it's a simple Glyph bar on the non-Pro and a full-on circular dot matrix display on the Pro. Getting technical for a bit, the Pro has 137 LEDs, while the regular has just 63. As you can imagine, you can do all sorts of clever stuff with the Glyph Matrix on the Nothing Phone (4a) Pro - animating your timer, different callers, you can even use it as a selfie display for the main camera.
The Nothing Phone (4a) has an excellent 6.78-inch 120Hz display with a 1224x2720px resolution and a peak brightness of 4,500 nits. Ticking inside is a 4nm Snapdragon 7s Gen 4, a newer-gen SoC than the 7s Gen 3 in this phone's predecessor, offering around 7% CPU and GPU performance improvements and a 10% efficiency improvement.
