I've had my biostrap for about a month now. The wrist strap is leaving sores on my wrist, I sent in photos via Twitter DM and haven't heard back. Anytime I attempt to switch to the "insights" tab in the app it keeps crashing. The activity tracker didn't log my activity either and I'm not sure if I'm really getting my money's worth. Going with 2 stars because the aspirations of this company are very high, but the service and product issues are a bit disappointing. Just got the ankle strap recently and want to really give it a thorough run through. Just hoping I didn't make the wrong product purchase. Would be happy to connect with a team member and discuss asynchronously via email.
