Piko: Water Tracker is a friendly, private place to manage drinks, daily goals, reminders, streaks and hydration progress. Log what matters, see what comes next and keep your routine flowing.
Designed for everyday hydration, Piko brings your water tracker, drink log, hydration reminders, progress charts and Home Screen widgets together without making a healthy habit feel like another job.
Piko can be used for free. Optional one-time purchases and subscriptions unlock Piko Premium. Available plans, pricing and purchase details are shown in the app before purchase.

YOUR DATA STAYS ON YOUR DEVICE
Hydration records are stored locally on your device and shared only with Piko’s widgets on that device. Reminders are scheduled on-device through iOS.
