Needled

Needled is the beautifully simple injection tracker for people on weight loss medications like Ozempic, Mounjaro, Wegovy, and Zepbound. Log your injections, track your weight, and always know how many doses are left in your pen - all in under 10 seconds. Free to download. Free to use. No meal plans. No calorie counting. No clinical jargon. Just the three things that actually matter on injection day. LOG INJECTIONS IN SECONDS Tap, confirm the date, done. Needled records your injection and updates your pen counter automatically. Set your schedule - weekly, twice weekly, or whatever works for you - and get a gentle reminder when it's time. On injection days, your dashboard shows a quick-log banner so you never forget. TRACK YOUR WEIGHT WITH CONTEXT Log your weight with quick-adjust buttons or slide to the exact number. Every entry can carry an optional label - like your current dose strength or a personal note - that shows up as a coloured phase marker on your progress chart. See exactly how dosage changes line up with your weight loss over time. KNOW YOUR PEN INSIDE OUT Tell Needled how many doses are in your pen and which dose you're up to. The app counts down for you and celebrates when you finish a pen with a summary of your progress: doses used, days on pen, and weight change. Got extra doses? Just keep logging. Need to match your specific dose count? You choose - 1 through 10. SEE YOUR PROGRESS CLEARLY A dedicated progress screen shows your weight trend over 1 month, 3 months, 6 months, or all time - with coloured phase markers showing your dosage labels. Below the chart: total injections, pens completed, average days between injections, and your current streak. PHOTO JOURNAL (PRO) Take progress photos and compare them side by side. Categorise by pose (front, side, back) and browse your transformation over time. Photos are protected behind Face ID or fingerprint - your journey stays private. CUSTOM METRICS (PRO) Track anything alongside your weight - waist measurement, blood sugar, body fat percentage. Create custom metrics that appear right on your dashboard. SMART REMINDERS Choose your injection days and set a reminder time. Needled sends a notification when it's time. Set separate reminders to log your weight too. MEET PIP Pip is your friendly teal companion who lives throughout the app. Pip celebrates your milestones, encourages you on injection day, and makes the whole experience feel warm - not clinical. WORKS FOR ANY INJECTION PEN While our community primarily uses weight loss medications like Ozempic (semaglutide), Mounjaro (tirzepatide), Wegovy, and Zepbound, Needled works for anyone who self-injects - insulin, B12, testosterone, Saxenda, and more. You configure your pen, your schedule, your doses. SET UP IN UNDER 2 MINUTES Tell us how many doses are in your pen, which days you inject, and your starting weight. That's it. SWITCHING FROM ANOTHER APP? Already tracking elsewhere? Import your injection and weight history so you don't lose your progress. FREE FEATURES - everything you need, always free - Injection logging with full history - Weight tracking with trend charts - Pen dose management and pen history - Injection day reminders - Dosage phase labels on charts - Dark mode, light mode, and system theme - kg, lbs, or stones and lbs NEEDLED PRO - optional extras for those who want more - Photo journal with before and after comparison - Custom metrics (waist, blood sugar, and more) - 7-day free trial, then a simple monthly or annual subscription Needled is a personal tracking tool, not a medical device.
