Soak is a simple water tracker and hydration reminder for people who want one-tap logging, visual daily progress, and a calm ad-free way to drink more water. Record water in one tap. The water surface rises as your daily intake grows, so your hydration goal is easy to understand at a glance. Set a daily water goal, review your water log, and use gentle reminders in the morning, midday, and evening. Unlike noisy health dashboards, Soak keeps hydration tracking focused: no account, no ads, no tracking, and no analytics SDK. Your logs stay on your device. Free features: - Water intake tracking - Daily hydration goal - Visual water progress - Recent water log and history - Gentle drink reminders - No account, no ads, no tracking Soak Plus is a one-time unlock for drink tracking beyond water. Track coffee, tea, juice, milk, sports drinks, energy drinks, sparkling water, smoothies, and more. Plus also adds estimated caffeine, sugar, and calorie views, along with more detailed history. Soak does not use HealthKit and does not read from or write to Apple Health. It is not a medical app, and hydration goals and nutrition estimates are general reference information only.
