I weighed nearly 26 stone. I'm approaching 60. And I never imagined I'd be launching my own app.

Hi everyone, I'm Lee Shaw, founder of WeightPilot GLP-1 Tracker.

At the beginning of this year, I weighed 25 stone 12 pounds (362 lbs). A conversation with my wife made me realise something had to change. I started Mounjaro in February and have since lost more than five and a half stone.

But managing GLP-1 treatment wasn't just about taking an injection. I needed to remember doses, rotate injection sites, monitor side effects, track my weight and pay attention to protein, water and food.

I wanted everything in one place. So I decided to build it.

I wasn't a software developer. I had no team, no investors and no fancy office. Much of the early work happened on a fishing chair, at my grandson's fold-up table, using a MacBook that belonged to my late son, Simon.

There were setbacks and plenty of things I had to learn. But I kept going.

What WeightPilot offers

WeightPilot helps people track injections, dose history, reminders, symptoms, weight, nutrition and progress. There are free reports, recipes, movement activities and barcode scanning. Optional Premium features include an AI Coach, AI Chef, meal plans and shopping lists.

I made the everyday tracking tools free deliberately. People may already be paying a lot for treatment. I didn't want them to have to subscribe just to log an injection or record their weight.

From a fishing chair to an international launch

WeightPilot launched on Google Play on 20 August 2026. It's now on iOS too, and available in more than 150 countries.

On 28 November, I'll turn 60. I still find it hard to believe that something I started because I needed it myself can now reach people around the world.

I'm not claiming WeightPilot is perfect, or that an app can replace medical advice. It's a practical tool built from lived experience, and I'm still improving it.

Why I'm here on Product Hunt

I'd really value feedback from people using GLP-1 treatments, healthcare professionals and fellow builders.

What would you change? What's missing? What would make it more useful?

I started out trying to change my own life. Somewhere along the way, I built something that might help other people too.

At nearly 60, I've discovered that it's never too late to start something new.

Thanks for reading and taking a look.
