Store description excerpt

Kelvin is a hardware-agnostic cold-exposure tracker — a gorgeous plunge timer, a session log with history and streaks, a breathwork trainer, and adaptation insights. Not a tub remote. Works with ANY cold source — ice bath, cold shower, lake, or chest-freezer tub. Kelvin owns the practice, not the tub. Master the cold — on any tub, shower, or lake. Every second in the cold, counted. WHY PLUNGERS CHOOSE KELVIN • A real timer, log and history that actually work. Breath-up rounds, a plunge countdown with a first-30s cold-shock breathing coach, and a guided warm-up. Built to log every session — the basics the category leader still misses. • Works with any cold source — no hardware, no pairing, no router, no $5,000 tub. Ice bath, shower, lake, freezer: pick a source and start. • Safety guardrails the whole category ignores — cold-shock and afterdrop guidance, a sensible exposure ramp, contraindication warnings, and a hard lock on breath-holds in or before water. Free, never paywalled. • Works offline, opens instantly — local-first, no account, nothing to crash. FREE FOREVER • The Plunge timer: breath-up, plunge countdown with first-30s cold-shock coaching, and a guided warm-up — for any cold source • Log sessions: temperature (C/F), duration, water source, how you felt, post-plunge clarity and mood • Streaks and a calendar heatmap: current and longest streak, total time-in-cold, longest plunge, weekly minutes • Breathwork trainer: box breathing and Wim-Hof-style rounds, with the safety lock that never lets you breath-hold in or before water • Safety guardrails: cold-shock and afterdrop guidance, exposure ramp, and contraindication warnings — free, never paywalled • Protocols library: beginner ramp, Wim-Hof-style, contrast (sauna to cold), athletic recovery • 90-day history, CSV export, local backup and restore • Large text, high contrast, reduced motion — accessibility is free KELVIN+ (OPTIONAL, 100% ON-DEVICE) • Adaptation insights: your cold-capacity curve, the temperature-by-duration tolerance trend, time-in-cold banked this month, best time of day, and mood correlation • On-device AI coach digest: a plain-language weekly recap and a personalized next-week ramp — your data never leaves the phone • Custom protocols and contrast builder, plus sauna and heat sessions • Goals and challenges and shareable streak cards • Unlimited history and advanced stats Built to be your cold plunge tracker, ice bath timer, cold exposure log, and breathwork trainer — all in one trustworthy place, on any cold source. Kelvin is not medical advice. Cold exposure carries real risks — cold shock, afterdrop, and, with breath-holds in or near water, shallow-water blackout and drowning. Consult a doctor before starting, especially with a heart condition, high blood pressure, or during pregnancy.
