A reduction to the essential. In a world of noisy dashboards and cluttered screens, Byku is built on a simple belief: the beauty of the ride lives in clarity. Byku is a minimal cycling computer designed explicitly for power meter training. It strips away distractions and presents your key data with typographic elegance and zero friction. Purist Performance. Byku is made for riders who value focus over noise. We replace complex menus with calm structure, and confusion with confidence. You get the essentials you actually need—Power, Speed, Time, and core ride metrics—presented with the elegance your bike deserves. Simple on the surface. Profound underneath. Completely focused on the road ahead.

Verdict
The clearest difference is in-app purchases: Gastón at none against Byku's 1. Gastón also leads on update cadence (monthly vs every 3 months) and iOS requirement (15.1 vs 26.2). On price, ads and device support there is nothing between them.
