Devs: Imagine a lithe, lightly-clad, sweaty body and what you'd do with it

Google has released the software development kit (SDK) for its Google Fit service.

Google Fit is yet another measure-your-activity-upload-it-socialise-it-track-progress-and-reward-you-for-achieving-goals service, but for Android. Google hopes the release of the SDK will spur device-makers to use Android on their gadgets, and also use Google services to store and crunch the data.

Google's playing nice here: it's insisting on these three conditions for developers who use the service:

• Fitness apps can store data from any wearable or sensor;
• Fitness apps can access data created by any app;
• User's fitness data is persisted when they upgrade their fitness devices.

Developers are also advised to “Always clearly explain to the user what data you will collect and why” and to “Honor user requests to delete their data”.

It's also forbidden to “ … use Google Fit APIs for non-fitness purposes, such as storing medical or biometric data, selling data, or using data for advertising.”

There's also a Google Fit app to be had in the Play store. The software will happily track how many steps you take each day, automatically if you let it.

So there you have it, developers. It's now entirely legitimate to start imagining lithe, sweaty bodies, and what you might do with them … in code. ®
