These days, Simon keeps things simple. He wakes up at 6AM and focuses on just three things: hitting 150 grams of protein, doing a 20-minute dumbbell workout, and getting to bed by 10 PM. He has been at it for three weeks straight, and already, he feels like a different person. He just wishes he had started 20 years sooner.

‍

Back then, though, he didn't have Spren.

‍

‍“I ended up talking about my decades of failures with weight loss”

A friend of Simon’s had invested in a tech company and sent him a number to text. “Some guy named Steve Lutsk who can help me lose weight,” he was told. 

‍

Turns out, Steve wasn’t a guy at all, he was an AI. “I kinda rolled my eyes,” he admits. “But my friend insisted I try it out, so I figured, what the hell.”

‍

What started as a few messages turned into something that felt like a therapy session. “Somehow, I ended up talking about my decades of failing at losing weight and the emotional toll that it had on me.” 

‍

Steve then told Simon to forget all the bad advice he had picked up over the years and focus on just three things that he personally struggled with. 

‍

Eat more protein. Strength train. Sleep better.

‍

“It sounded doable, I guess, but that wasn’t the end of it. Steve sends me automated reminders to hold me accountable. At 7 AM, I get a text making sure I eat 50 grams of protein for breakfast. At noon, another one reminds me to get in a quick workout at my office. And at 8 PM, I get a nudge to put my phone away and spend time with my family.”

‍

Every Monday, Steve also has Simon do a body scan with Spren using his iPhone. He started out at 27% body fat, and just yesterday, he saw that he had dropped to 25%. “It’s not a huge change yet, but it’s the first time I’ve actually seen something clearly working.”

‍

For Simon, he’s off to level 2. “This Monday, Steve texted me and told me I’m ready for the next goal, 7,500 steps a day. The first two days went well, I’m averaging ~7K or so. Steve can automatically see how I’m doing every day through my Oura. And of course, he’s going to text me everyday to make sure I get moving.”

Why Spren?

Spren started with a simple idea: make tracking your health easier and more accurate. Using just an iPhone, it can measure body composition changes and heart rate variability (HRV), two key markers of both physical and mental well-being.

‍

But tracking alone isn’t enough. That’s why Spren worked with some of the best fitness coaches to create one-on-one guidance and turn all those insights into actionable guidance. Whether it’s tweaking your workouts, adjusting your macros, or nudging you to recover better, it gives you the kind of personal coaching that most people never get.

‍“Coach J tells me in five minutes if I’m gaining muscle”

Andy, 47, has spent a lifetime working in VCs, always putting work before fitness. Now that he finally has time to focus on his health, his goal is to get down to 18% body fat. He’s tried everything: food logging apps, training programs, online coaching, wearables, but despite all the data, something was missing. Since working with Jason Helmes’ AI-powered coach, he’s finally found the personalized approach he couldn’t get before. In his own words:

‍

"I hate having so many apps. I’d track my workouts in one, log my food in another, check my sleep in Oura. I also weigh myself everyday. But even with all that, I wasn’t sure if I was actually making progress. Now, Coach J tells me in, like, five minutes if I’m gaining muscle or just getting fatter. It tweaks my workouts, tells me what to focus on, and even helps me figure out what to eat. Honestly, I don’t even know if I need all those other apps anymore."

‍“It’s encouraging, very encouraging”

Chris is no stranger to tracking his health. Every morning, shares his blood pressure and heart rate variability (HRV) with Caroline Jordan’s AI-powered coach. Managing his health isn’t simple, he’s working around hypertension and a past knee injury, but he’s determined to get in shape.

‍

"I've got a specialist for everything, a personal trainer, a dietitian, a naturopath, you name it. But this morning, I got the most motivating message from Coach Caroline. It said, ‘You’re absolutely crushing personal records. Let’s break it down.’ So I told it what exercises I did and asked it to dig deeper. It broke down what muscles I was working on: chest, shoulders, triceps and then it said, ‘Personal bests like this show that you’re training at an athletic level.’ That’s encouraging. It’s very encouraging."
