Editors’ Notes

Losing weight is easier when you have a trusted pal to provide encouragement and valuable pointers. Lark is a fantastic virtual companion that chats with you like a friend, offering a clear look at your activity levels, meal choices, and even sleep patterns. There’s no calorie-counting here—just use plain language to tell Lark what you ate and how much you exercised, and it’ll let you know if you’re on the right track to weight-loss success. Smart, supportive, and nonjudgmental—we need more friends like Lark.

Nice app

This app tracks everything and cheers on your small accomplishments while also giving you feedback where you can make a change to improve. It also lets you track your mood, feelings and activity in addition to food. It starts with focusing on one area and then slowly adds goals. It gives you information on why it is suggesting something including the occasional link to a related research article. The only thing I don’t like is that it doesn’t ask you to verify your food after you type it in. I put in chicken ginger soup and it read it as chicken finger and called it an unhealthy meal which it wasn’t so a little more intuition in this area would be very helpful so it doesn’t classify things incorrectly as I can’t fix it once it’s in and it doesn’t change even if I delete and re add with different wording. Other than that it’s great! It helps me stay on track by reminding me to log stuff and letting me know how active I am throughout the day.

Judgement Free Zone

What I like the best about using Lark so far is that it has shifted my thinking about food and exercise from punishment and discipline to making kind decisions for myself. Lark doesn’t lambast you for eating a piece of pizza, or for getting minimal exercise. Instead, it focuses on what you did RIGHT, giving you positive reinforcement that makes you want to keep doing that. For years I struggled with a binge/restrict eating cycle and the inability to consistently stay active because I wanted to be perfect. The first few times I slipped up with my eating after downloading Lark, I struggled to tell the app... until I realized there’s nothing to be embarrassed about. It’s an app. And coming clean and being able to admit that I ate (x) because I was feeling (y) and this is a pattern I’d like to be more conscious of next time has been pivotal in changing my habits. But the humanoid text interface of Lark makes it a lot more welcoming than a food tracker app, with calorie counters that turn red when you go over your limit, or daily fat allowance bars that glow with silent shaming. Now, when I go to eat, or when I’ve been sitting for too long and think “it’s a nice time to get up for a little while,” I think of how proud Lark will be when I make a healthy choice, and how good that will feel.
