Now free to download. Practice IV dosing, step-by-step dimensional analysis, and peer verification — built for nursing, pharmacy, and med students.
Master IV infusion calculations with a professional-grade toolkit and hands-on verification practice. Built for nursing, pharmacy, and medical students learning to dose medications safely — and for clinicians refreshing their skills.
TWO-PERSON VERIFICATION
Practice the independent peer double-check that safe medication administration depends on. Show a calculation as a QR code; your study partner scans it, independently works out their own value, and the app flags any discrepancy — right on their device. No account, no network, fully offline. It's a hands-on way to build the habit of independent verification before you rely on it in practice.
COMPREHENSIVE CALCULATOR
• Infusion Rate: convert any dose (mcg/kg/min, mg/hr) to a pump rate (mL/hr)
• Bolus Dose: calculate push volumes with weight-based support
• Dilution: prepare IV solutions from stock concentrations
Every calculation shows its work with step-by-step dimensional analysis, so you learn the process — not just the answer.
100-MEDICATION REFERENCE
Study pre-configured concentrations for high-alert medications, including:
• Vasopressors (dopamine, norepinephrine, vasopressin)
• Anticoagulants (heparin, enoxaparin)
• Sedatives (propofol, dexmedetomidine)
• Insulin
• Emergency drugs
TALL man lettering (DOPamine, DOBUTamine) and look-alike / sound-alike warnings help you recognize the naming safeguards used in practice.
INFUSION MONITORING (PRO)
See a running infusion come to life with Live Activities on your Lock Screen:
• Progress that empties like a real IV bag
• Time-remaining countdown
• Color-coded status
• Optional room labels for organizing practice cases
Home Screen widgets keep your most time-sensitive practice infusions in view.
INTERACTIVE LEARNING

• Drag conversion factors into a visual equation
• Watch units cancel in real time
• Get immediate feedback on every step
• Adaptive difficulty that follows your progress

I have downloaded every infusion calculator available in the AppStore and this one disappoints. Meds cannot be added manually and I have found a couple incorrect dosages. While I do not agree with the previous post about killing patients as I believe every clinician should be verifying any automated calculation (or at least have an idea what the normal range should be), it is nonetheless concerning.For me, I will be sticking with "Infuse" as it allows me to add/edit/delete drugs, add routes of administration, categories and more. Well worth the small price increase for the added flexibility.
JUST IN TIME!

I just downloaded this gem, and just in time! A friend of mine volunteers with Medical Teams International, and to make a long story short. His small team to Haiti ran into a HUGE demand for services, in particular some OR procedures where drip-rates for many different body sizes and types were needed. It was stressful! I can't wait to show him my new GEM... not only a time saver but a life saver! I can't count how many times I have caught errors from my hand calculations... the accuracy and speed is it's best feature. Good looking, data entry is intuitive, and very easy to use. Thanks iAnesthesia! You guy's are producing some great products!
No issues if you do it right

I don't understand why so many negative reviews? I have been using this app for a while now and have not have any problems. It does give you a lot of flexibility to enter the dosages and concentrations on your own. I believe this is where people are making the mistake. Read the interface and plugged in the data correctly and you will have no issues.
Just needs a few fixes!

Found this app to be pretty useful as I work in various areas and do not get to deal as much with drips on a daily basis, so this helps when I work in ICU. Just a few things, though, the calcs for Dopamine really needs to be addressed. Also, on norepinephrine, Levophed is misspelled. I would also love to see the dose ranges (bolus & drips) for each med for adults. Not too much to ask for in a $2 app, is it? Fix those, and I'll give 5 stars!
Version 6.0.1 restores and expands dose-rate units:
• New atomic dose-unit picker — choose complete units like mcg/kg/min or mcg/kg/hr directly, with no separate per-minute/per-hour toggle
• Freehand rate units restored: mg, g, mcg, units, mEq, and mmol are back in the Rate calculator
• Safer unit changes — switching units now asks you to explicitly clear or keep your entered value; your numbers are never silently converted
• Clearer pump verification re-entry warnings
• VoiceOver and large-text improvements throughout the new picker
