Stash Diabetes - Track every diabetes supply, and spot bad lots together

Hey Product Hunt! I'm Cory, and I've lived with type 1 diabetes for 22 years. The whole time, I've managed my supplies the way most people with diabetes do — a Post-it on the fridge, or an out-of-date notes app that never reflects what's actually in my closet or fridge. No visibility into what's in use, what's expiring, what's under recall, or when I'd need to reorder. Every diabetes app on the App Store is built around the clinical side: tracking glucose, counting carbs, calculating insulin doses. None of them help with the actual logistics of staying alive, answering questions like "do I have enough sensors for this trip?" or "is this pod safe to use?" A 2024 study in Frontiers in Clinical Diabetes and Healthcare found that for many people with T1D, obtaining and managing supplies is the hardest part of living with diabetes — harder than the day-to-day management itself — and a real source of diabetes distress. The same study found people lean on peer communities (one participant called discovering a T1D subreddit "a whole new world") for the practical problems formal care misses. That matched my experience exactly. So I built Stash — the supply tracker I needed but couldn't find. Calm by design, minimal by default, quiet on notifications, because everyone managing diabetes already has enough going on. What's in it: - Inventory tracking for pump supplies, CGMs, insulin vials, test strips, ketone strips, and more - Automatic recall notifications for critical supplies - Community reporting of faulty devices, so users can flag a bad lot and warn others - GLP-1 and oral medication tracking - Multi-location support to track supplies at home, work, school and beyond - Body site and injection tracking so you stop reusing the same spot and let your skin heal - Trip planner for anxiety-free travel of any length - Shared views so partners, parents, and caregivers can stay informed on your inventory - Home screen widgets so you can build your own iOS dashboard Where we are: In just over 12 weeks, Stash has crossed 2,500+ users across 53 countries, with a 4.8 rating on the App Store and a 19% average conversion rate — nearly 1 in 5 people who see Stash download it. What's next: - Strategic partnerships with diabetes nonprofits and device manufacturers to surface real-world device failure data, with the goal of better outcomes for people with diabetes - Android support, to reach an additional 4–6M people Stash is free, and the core features — inventory, recall alerts & community reports — always will be. My goal is to keep the full app completely free for everyone, subsidized through partnerships with device manufacturers, distributors, and researchers, rather than charging the people who need it. Would love your feedback. And if you live with diabetes — or care for someone who does — I especially want to hear from you. Drop a comment or DM me. Cory Zapatka Founder, Stash Diabetes
