Accessing new streams of data about ourselves can provide important information to live a healthier life and to make this sustainable this data would need to be collected with no user input. Here is a water bottle that lets you know how much water your drinking.

With the advent of low power bluetooth devices the Hidrate Spark 3 water bottle become possible. This bottle feels like it is made by a technology company who seamlessly incorperated bluetooth into a water bottle. As opposed to a water bottle manufacturer trying to put bluetooth tracking into their most popular line.
The bottle has great build quality, with it having a grippy not sticky grip. It glows as a reminder to drink and all this is powered by a coin battery in the base. The bottle is filled with water same as any other water bottle and it collects data without user input.
The app has a built-in tracking system showing the last location where the smartphone and water bottle were in proximity.
This device is well designed and seamlessly collects my water consumption without a single sync via the app. Just topping up with water and drinking is enough. The app also provides random reminders to drink and which can exclude night time hours. This device just works with no user input.
The app is well made and syncs both with Fitbit and has an iOS widget, the statistics are made easily available across multiple platforms. The app sends out humorous notifications when it’s time to drink. I’m sure with time the novelty will wear off and the feature will be turned off, but as an overall package this feels very much like a complete product.
The Hidrate Spark 3 is available from Amazon UK
