Your medication does the heavy lifting right after a dose. Your habits take over as it tapers. Blūm is the only app that knows the difference. Blūm is a GLP-1 companion built around one idea: the effort you need from your habits should change depending on where you are in your medication cycle. YOUR BLŪM SCORE Your score has two parts, and together they make 100%. Your estimated medication level fills the first part. Blūm models where your medication may sit in your body using published pharmacokinetic data specific to your drug and dose. It rises after your shot and falls as your body metabolizes it. Set it once and it updates on its own. Your five habits fill the rest: protein, hydration, sleep, movement, and calorie balance. Blūm keeps the focus on the habits that matter most, without turning your day into a checklist. When your medication level is higher, you need fewer habit points to reach 100%. As it drops, your habits carry more of the weight. The right amount of effort at the right time, every day of your cycle. LOGGING THAT TAKES SECONDS Voice. Log meals, water and side effects just by speaking. Photo. Snap your plate and AI estimates protein, calories and macros. Manual. Search and log the normal way when that’s faster. YOUR GLP-1 CHEF Tell Blūm what medication you’re on, how many weeks in you are, what side effects you’re dealing with and how you like to eat. Your Chef builds meals around all of it. Ask for swaps, change the macros, tell it what you hate, or build a full meal plan. Keep chatting until it fits you. When you’re ready, add the ingredients straight to Instacart. MEDICATION TRACKING Semaglutide, tirzepatide, retatrutide and compounded formulations supported. Log your dose and schedule once. A visual body map tracks your injection sites so you never second-guess where you went last. COMMUNITY Whatever stage you’re in, someone here gets it. Every question, setback and win feels easier when you’re not doing it alone. Join discussions, ask questions, share wins, reply to people on the same road, or just scroll and take it in. Topic tabs keep the feed easy to navigate. Peer support only. Never medical advice, never a substitute for your provider. PODS Create a Pod and invite your people. Friends, family, or anyone walking the same road. A smaller group to check in, support each other and stay accountable. SIDE EFFECTS Log them over time, spot patterns and see what was happening when you felt your best or worst. HEALTH REPORT Pick a period, tap generate. Weight, BMI, body measurements, side effect trends and your dosing log in one PDF, with space for provider notes. Hand it to your provider instead of trying to remember weeks of changes. YOUR PROGRESS Track your weight and watch the months, not the mornings. Follow body measurement changes, add photos to your weight journey and see how far you’ve come. ASK ANYTHING Wondering if a side effect is common? Not sure how to hit your protein target? Blūm’s AI draws on our GLP-1 learning library to answer in plain language, in the context of your own data. No more midnight Googling. ALREADY TRACKING SOMEWHERE ELSE? Apple Health syncs steps and sleep automatically. Data import brings your history from other GLP-1 apps in about a minute. Nothing gets lost. Blūm is a companion app, not a medical device. It does not diagnose, prescribe, or replace your provider. Always follow your prescriber’s instructions.

Verdict
The clearest difference is ads: Formulate at none against Blum's shown. Formulate also leads on update cadence (every 3 weeks vs every 2 months) and iOS requirement (15.1 vs 26.2). On price, in-app purchases and device support there is nothing between them.
