ChillSeeker is a focused tracker for your cold plunge and sauna sessions — built for iPhone and Apple Watch, and built to stay out of your way. LOCAL-FIRST, BY DESIGN No servers. No account to create, no email to enter, no analytics SDKs, no third-party trackers. Every session, journal entry, and health insight stays on your device. Export your data as JSON or CSV any time, or delete everything with one tap. DEAD-SIMPLE START AND STOP A giant START button. A press-and-hold STOP so a wet hand never ends your session by accident (switch to one-tap in Settings if you prefer). The timer survives backgrounding, screen lock, and force-quits. ONE APP, TWO MODALITIES Cold plunge and sauna live side-by-side, each with their own stats, streaks, and color theme. Switch with a tap. APPLE WATCH COMPANION Start and stop a session right from your wrist, with live heart rate. Sessions sync back to your iPhone automatically. HANDS-FREE WITH SIRI "Hey Siri, start a ChillSeeker session." Map it to the Action Button on iPhone 15 Pro and later for a one-press start. BREATHWORK BUILT IN Box, 4-7-8, Power Breaths, Calm Down, and Coherent — five timed patterns with haptic phase cues. Attach a length-matched warm-up to any session as a "prepare" step before the timer starts. AN ON-DEVICE COACH Ask about cold temperatures, durations, contrast therapy, breathing technique, or workout timing — and get clear, grounded answers. Say "build me a routine" and it puts one together from your own recent sessions. Runs entirely on your device. No chatbot, no servers. SMART SUGGESTIONS Conservative, progressive, and transparent. Eases beginners in, only suggests colder or longer after consistent good sessions, and backs off when recovery signals — HRV, perceived difficulty, feeling-after — trend poorly. Every suggestion shows its reasoning, and you can always override. HONEST INSIGHTS Eight clean charts: sessions over time, duration, temperature, heart rate, HRV, feeling before/after, time of day, and a day-of-week heatmap. Plus plain-language observations — never medical claims. GOALS, STREAKS, BADGES Weekly, monthly, or all-time goals per modality. Streaks allow one rest day per week before breaking. 23 badges across streaks, endurance, milestones, exploration, and consistency — each unlocks with a celebration moment. REFLECTION JOURNAL A quick post-session note, or a longer entry with mood and a photo. Link to a session or stand alone. Search by text and filter by mood. SCHEDULE & REMIND Put a session on your calendar with a reminder, or set recurring per-weekday reminders so you stay consistent. APPLE HEALTH + BLUETOOTH With your permission, ChillSeeker reads heart rate, HRV, resting HR, and body temperature, and writes sessions as workouts plus breathwork as Mindful Minutes — all on-device. Pair a Bluetooth thermometer to log water temperature automatically, and play a song or playlist from Apple Music during your session. PRICING Try every feature free for 7 days. Then a one-time $4.99 unlocks ChillSeeker forever — no subscription. A WORD ON SAFETY ChillSeeker is a general-wellness tracker — not a medical device, not medical advice. Cold immersion and sauna use carry real risks. Consult a doctor before starting. Never plunge alone. Stop immediately if you feel unwell. Full disclaimers appear during onboarding and any time in Settings. REQUIREMENTS iOS 17 or later. iPhone, with optional Apple Watch. ## Key features - Local-first data storage - Cold plunge and sauna tracking - Apple Watch companion app - Built-in breathwork timer - On-device AI coach - Smart session suggestions - Detailed health insights and charts ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | ChillSeeker Lifetime Unlock | $4.99 | one-time | ## Frequently asked questions about ChillSeeker ### What is ChillSeeker's pricing model?
