Top comment
I built Ramp4x4 because the Norwegian 4x4 is simple on paper but awkward to execute well: nine phases, a heart-rate target, and a phone–Watch handoff while you’re already working hard. Generic timers make you do the math and manage the clock. Ramp4x4 turns the protocol into a one-tap guided session with live heart-rate coaching, voice cues, haptics, and a clear post-workout interpretation. For v2 I focused on the things that make people come back: a dedicated TRAIN flow, a complete 8-week plan, richer workout-quality analysis and Cardio Fitness trends, support for Apple Watch, compatible Bluetooth HR monitors and Timer Only, plus much stronger workout recovery and phone–Watch reliability. I’m an independent builder at Archline Labs, and I’d genuinely love feedback from runners, cyclists, rowers, Watch users, and anyone trying to make VO2-focused intervals a sustainable habit. What would make this the training tool you’d trust twice a week?
