Everything your GLP-1 journey needs, in one free app
The medication works. Nobody tells you what to do between doses.
Your prescription doesn’t come with a playbook. Is the nausea normal? Why did the scale stall this week? Are you eating enough protein to keep your muscle? Should you feel this tired three days after your shot?
Blūm answers the question every GLP-1 user asks: “is this working, and what should I do today?” It connects your medication cycle with the five daily habits that drive results, so you always know where you stand.
SHOT LOG
Never miss a dose. Never forget a site.
Log every injection in seconds. Blūm tracks your dose history, counts down to your next shot, and maps your injection sites so you rotate properly. Works with weekly, custom and titration schedules, branded or compounded.
MEDICATION LEVELS
See what your body can’t tell you.
Blūm models your estimated active medication levels using published pharmacokinetic data for your exact drug and dose. Know when you’re at peak, when levels are fading, and why some days feel harder than others.
FOOD LOGGING · NORA AI
Snap a photo. Nora does the math.
No more searching databases for every ingredient. Take a picture of your plate and Nora AI estimates calories, protein, carbs, fats and fiber instantly. Prefer another way? Scan a barcode, search the database, use your voice, or enter it manually.
SIDE EFFECT TRACKING
Your symptoms, on a timeline your doctor can actually use.
Track nausea, constipation, fatigue, heartburn, food noise, appetite suppression and more, right alongside your dose days. Spot patterns like rough days after a dose increase, and walk into appointments with real data instead of vague memories.
NORA ASSISTANT
A GLP-1 expert in your pocket.
Ask Nora anything: “Recipe to hit 49g of protein?”, “What if I get nauseous after my injection?”, “How’s my weight loss trending?” Nora is trained on 100+ expert GLP-1 articles and knows your actual data, so answers are specific to you.
THE BLŪM SCORE
One score. Your whole day, at a glance.
Your Blūm Score combines your medication levels with five daily habits: protein, hydration, sleep, movement and calorie balance. When your levels are high, the medication carries you. As they drop, your habits pick up the weight. Hit 100% and your flower reaches full bloom.

What exactly is Blūm?
Blūm is a free companion app for people on GLP-1 medications: semaglutide (Ozempic, Wegovy), tirzepatide (Mounjaro, Zepbound), retatrutide, liraglutide, and compounded formulations. It tracks your shots, models your medication levels, and connects them to the five daily habits that influence your results: protein, hydration, sleep, movement and calorie balance.
How much does Blūm cost?
Nothing. Blūm is 100% free with no subscription, no trial countdown, and no paywalled features. Download it and use everything.
Why is it free?
We believe everyone on a GLP-1 deserves proper support between doses, not just people who can afford another subscription on top of their medication.
Is Blūm on Andriod?
Not yet. Blūm is currently iOS only. Android is on the roadmap.
Is Blūm a medical app?
No. Blūm is an educational and habit-tracking tool. The medication modeling uses published pharmacokinetic data to estimate your active drug levels for personal awareness, not clinical decision-making. Blūm does not provide medical advice, diagnose conditions, or replace your healthcare provider.
How is Blūm different from MyFitnessPal, Noom, or other health apps?
Generic apps weren’t built for GLP-1 users. Blūm models your estimated medication levels, tracks the five habits most relevant to GLP-1 outcomes, and ties everything into one score and one visual: the Flower. When your medication levels are high, you need less from your habits. As levels drop, your habits carry more of the weight. No other app adapts to your cycle like that. And unlike the GLP-1-specific competitors, Blum is completely free.
How does the Blūm score work?
Your Blūm Score combines two things: an estimate of your active medication levels and points earned from five daily habits: protein, hydration, sleep, movement and calorie balance. When your estimated levels are high, you need fewer habit points to reach 100%. As levels drop between doses, your habits carry more of the weight. Hit 100% and your flower is in full bloom. It resets every morning, so each day is a fresh start.
How does food logging work?
Four ways: Snap a photo and Nora AI estimates the macros, Scan a barcode, Search the food database, or Enter manually. Most users find photo logging fastest.
Does Blūm track side effects?
Yes. Track nausea, constipation, diarrhea, fatigue, heartburn, food noise and suppressed appetite on the same timeline as your doses, so patterns are easy to spot and easy to show your doctor.
Does Blūm work with my specific medication?
Blūm supports semaglutide, tirzepatide, retatrutide, liraglutide, and compounded GLP-1 formulations, whether your prescription comes from a doctor, pharmacy, or telehealth provider. The pharmacokinetic modeling adjusts to your specific medication and dose.
Is my data private?
Your health data stays on your device and is never sold to third parties. Community features like Pods only share your Blūm Flower status, not your underlying health data, unless you explicitly choose to share more.
Your GLP-1 works better with Blūm.
