ColdPlunge Pro

ColdPlunge Pro is a private interval timer and session log for cold-shower and cold-plunge routines. Choose a conservative preset, run a simple Prep, Hold, and Rest timer, then optionally save water temperature, perceived effort, and a short note. Your sessions stay on this device. Free includes the bundled presets, the timer, reminders, and the last 30 days of history. Premium unlocks full saved history and CSV export. Built for a quiet local workflow: - No account - No ads - No analytics - No cloud sync - No third-party SDKs ColdPlunge Pro is a timer and private log only. It does not choose routines for you. Use only routines you already know are appropriate for you, and stop if you feel unwell.
