Download for free. Lark is now available for all iPhones, AppleWatch, and Android devices, and is preinstalled on new Samsung phones.
Say goodbye to doing it alone with a tedious calorie-tracker: instead, tell Lark what you're eating and she'll text you back in 2 seconds.
"Lark actually cares about how I'm feeling. I can check in anytime throughout 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 this app keeps me accountable and motivates me to beat my daily average."
"Lark has helped me lose 20 pounds and I feel great! ...Because of how user friendly Lark is, I have made it the only weight loss app on my phone."
Lark helps you stick to whatever weight loss or workout plan you choose: Lark automatically tracks your exercise from your phone's sensors, and coaches you to get more active based on your daily activities.
