Springaroo keeps count of what you drink, against a figure for your day — worked out from your body mass, what you have planned, and the sky you pick for the day.

Coming soon to the App Store, for iPhone.

• Stays on your phone. No account, no sign-in, and the app sends nothing anywhere.
• A figure for your day. It changes with what you are doing and the sky you pick. Reminders come only during your activity and as a summary in the evening, and say only how much you have logged.
• Your dog too. Add your dogs and see their water beside yours.

Springaroo is a water tracker, not medical advice. If a doctor has given you a fluid target, follow theirs.
