Flic should be able to track fitness. Also you guys have to make sure you use a good silicone beacuse i feel like the bright colors with get dirty easily. Adding a microphone to flic would enable calling through flic without pulling out the phone. Adding apple pay would be another good feature. Making a flic that is bendable to fit on any surface would also add more placement options. Finally making custom silicone cases for full customization and personalization.
