WalkingTestApp

Use this app for doing the 6 minutes walking test. You can add your contacts and then you can share your tests on email with those contacts. Regarding your data it's saved in iCloud private database, so it's yours personally and isn't shared with anyone else. With the adding of use of your location when in use, it will be possible to calculate the distance walked and those locations are NEVER saved or nor shared, so there's no need to fear that.
