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.

Simple health app

This app is very helpful for people wanting to start or continue a more health conscious journey. It is simple to use and guides you through tracking food, activity, sleep, wellness, and mood daily. Provides easy to follow feedback and encouragement. Gives resource links and info on it’s feedback when needed. Allows you to fully edit wrong entries on food and asks if activity levels look correct - then reminds you that micro activities like cleaning, etc can be manually entered to capture more correct data. This is a fantastic add-on tool to track important data and be able to use on your own or in conjunction with a doctor to give him/her insight into your health related behaviors.
It seems it will work more efficiently with a FitBit for activity tracking, however, it is not absolutely necessary. I’ve been using it without and still enjoy the simplicity and daily feedback to keep me focused.
You are able to change the times of activity or meals so you aren’t tethered trying to enter data in real time.

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.
