A free 14-day Starter ramps you into cold showers with a huge hands-free timer and honest safety guidance. Five more graduated plans, full stats, and CSV export with Pro. Shiver turns cold showers into a graduated challenge instead of a dare. Start warm, ease into a cold finish that grows a little every day, and build a streak — all timed hands-free by a huge, eyes-closed-friendly in-shower clock. No ice bath, no chest freezer, just your own shower. HOW IT WORKS Pick a plan and Shiver tells you exactly what to do that day: how long to stay warm, how long to finish cold, and when each phase changes — announced with haptics and a chime so you never have to open your eyes or step out of the spray to check a clock. SIX GRADUATED PLANS - 14-Day Starter (free) — the beginner ramp: a cold finish that grows from 15 seconds to 90 over two weeks - 30-Day Full Cold — the warm-up shrinks away while the cold grows to a full 4 minutes, fully cold by day 13 - Contrast Protocol — 14 days of hot/cold intervals, always ending cold - 11-Minute Week — four sessions a week totalling 11 cold minutes, with rest days built in - 90-Day Ice Ladder — a slow three-month climb from 30 seconds to 5 minutes of cold, with a weekly rest day through week 12 - The Reset — a 7-day comeback ramp for after a broken streak, from 15 seconds back to 2 fully cold minutes SAFETY FIRST Cold exposure is a real physiological stressor, not a stunt. Before your first session Shiver walks you through the cold-shock response, the conditions worth checking with a doctor about first, and the signs that mean stop right away — written in plain language, never buried, always one tap away in Settings. Shiver only ever measures you against your own past sessions, never against anyone else. TRACK WHAT ACTUALLY HAPPENED A completed session logs itself — duration, cold time, and plan day — then you add how it felt: mood before and after, and a 1-to-5 snowflake cold rating. Watch it build into a streak and a calendar heatmap. EARN BADGES Fourteen achievement badges for showing up — streaks, sessions, cold minutes, plan milestones. Always visible, so every badge is a goal, never a secret. SHIVER PRO The 14-Day Starter, the timer, and your log are free forever. Subscribe to unlock: - All five premium plans — 30-Day Full Cold, Contrast Protocol, 11-Minute Week, 90-Day Ice Ladder, The Reset - Silent breathing prep before the cold — a guided box-breathing pattern, seated, visual and haptic only, never during the shower - Full stats — the weekly cold-minute meter, your mood shift, trends - Retro-log a missed day and repair your streak - CSV export of your whole session log - Unlimited timer presets (free keeps one) - Apple Health sync — completed sessions saved as mindful minutes (write-only, never reads your data) Subscriptions renew automatically unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in your App Store settings. Payment is charged to your Apple ID. Shiver is a habit and timer app, not a medical device. It does not diagnose, treat, or prevent any condition. If you have any concern about whether cold exposure is safe for you, talk to a healthcare professional first.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

A visual tune-up across the app. - Mood and cold-rating icons are now crisp custom artwork instead of emoji, so your log stays sharp at every text size. - The Plans screen gives each plan its own icon, length and status at a glance: active, completed, or ready to start. - The "done for today" card on Today is clearer about what you banked and what tomorrow holds. - Tab icons now fill in when selected. - Fixed a back button that showed the wrong label, and a "Change plan" link that could sit off-screen at the largest accessibility text sizes.
