My Lark coach actually cares about how I’m feeling. I can check in anytime through the day on my phone. The fact that it’s like talking to someone is wonderful.


I check Lark multiple times a day and I love that the Lark coach keeps me accountable and motivates me to beat my daily average.

I feel like I have a personal, friendly coach who accepts whatever I do while educating and encouraging me to do more. The coach helps me feel like my exercise and eating portions of my life are no longer out of control. I appreciate knowing the friendly, helpful coach is always available. I've lost weight and gotten more active.
