NutriStack vs PepTrack

NutriStack is a supplement tracker and interaction checker built on real evidence. Add your supplements and medications and instantly see where they interact, where they work in synergy, and how strong the research behind each one really is. It is the safety check most supplement apps leave out. CHECK FOR INTERACTIONS See potential interactions between your supplements and your medications, with clear explanations and what to do about them. This is NutriStack's core. Most apps log your pills; few tell you whether they belong together. SCAN AND GRADE (NEW) Scan a large new database of supplements and get an instant grade based on quality and the evidence behind each product, so you can tell a genuinely good formula from good marketing. ASK THE AI (NEW) A built-in AI that answers your questions from NutriStack's own research and interaction database, not the open internet. Ask about timing, combinations, or what the evidence says and get an answer grounded in the app's own data. BACKED BY RESEARCH Thousands of supplements and studies with real citations and evidence grades, so every claim is something you can check for yourself. This update adds more studies and broader interaction coverage. TRACK WHAT MATTERS Log doses and timing, keep your daily routine on track, and see your whole stack at a glance with a stack quality score. WHO IT IS FOR Anyone taking more than a couple of supplements, from beginners who just want to stay safe to enthusiasts optimizing a complex stack.

PepTrack is the serious, private tracker for people managing GLP-1s and peptides. Your doses, sites, schedule, and progress — organized, on your device, and ready to hand to your doctor. Most people on this journey are tracking everything in their head, in a Notes file, or on a napkin. PepTrack gives it a proper home, with the polish of a premium app and none of the guesswork. WHAT YOU CAN DO • Reconstitution calculator — enter your vial strength and the dose you want to draw, and see the result on a clear, true-to-scale syringe. It does your arithmetic, precisely, every time. • Injection log with site rotation — record each injection in seconds and rotate sites on a visual body map, so you always know what you did and where. • Active Levels — a half-life visualizer that charts your logged injections over time, so you can see your own pattern at a glance. • Weight & BMI dashboard — sync with Apple Health to chart weight, body fat, and BMI. Watch the trend line, not the daily noise. • Schedule, reminders & widget — build your own dose schedule and titration steps, get gentle reminders, and keep your next injection on the Home Screen widget. • Doctor-ready export — export a clean PDF or CSV of your history and walk into appointments prepared. PRIVATE BY DESIGN Your information is stored on your device, and — only if you choose — in your own private iCloud. There's no required account, no ad networks, and we don't sell your data, because we never collect it. Lock the app with Face ID if you like.
