I am still in the ICU applying to CRNA school — is this useful before I start?

Yes. Set your path to CRNA/SRNA and the Daily Recall Run drills anesthesia pharmacology, hemodynamics, and airway, so you sharpen the deep reasoning that applications and interviews tend to probe — well before day one of didactics.

What does the anesthesia content actually cover?

The CRNA/SRNA path stays anesthesia only, centered on pharmacology, hemodynamics, and airway. Coverage is mapped to published content domains and is educational, not exhaustive, and it is not affiliated with any certifying body.

Is the daily run really free?

Yes — the Daily Recall Run is free forever, and free users are never blocked from learning. Recall+ and Recall Pro tiers add more, and any purchase happens through Apple In-App Purchase inside the iOS app.

Can I study from my own program's slides and drug handouts?

Yes. Upload a PDF, slide deck, or a photo of your notes (up to 10 MB) and turn it into a summary, study guide, flashcards, a practice quiz, or a concept map. You get one free preview with no signup.

Will this guarantee I pass boards?

No — nothing can, and we will not claim it. RecallOS builds durable recall through a short daily habit. Exam Predictions are AI estimates to help you focus your studying, never a guarantee of a score or an outcome.

It was built by a practicing CRNA (nurse anesthetist), so the anesthesia framing, high-yield emphasis, and daily-habit design come from someone who has walked the path and works in the field.

For ICU nurses applying to CRNA school and current SRNAs

A daily anesthesia study habit, built by a practicing CRNA

RecallOS is a daily study app made by a practicing CRNA (nurse anesthetist) for the people walking the anesthesia path — ICU nurses building a competitive application and SRNAs deep in didactics. Set your path to CRNA/SRNA and your Daily Recall Run serves anesthesia only: pharmacology, hemodynamics, and airway. A few honest minutes a day, so the hard stuff sticks long before boards.

The problem

Anesthesia didactics arrive like a firehose — MAC values, induction agents, vasoactive drips, receptor pharmacology, ventilator waveforms, difficult-airway algorithms — and most of it is reviewed once, then forgotten by the next block exam. ICU nurses prepping CRNA applications feel the same gap: strong at the bedside, rusty on the deep pharm and hemodynamic reasoning interviews probe. Cramming the weekend before an exam moves knowledge into short-term memory, then lets it evaporate. What anesthesia training rewards is durable recall under pressure, and that is exactly what a once-and-done study session cannot build.

How RecallOS helps

Anesthesia only, by design

Choose the CRNA/SRNA path and every question stays in your lane — anesthesia pharmacology, hemodynamics, and airway. No stray med-surg or general nursing content diluting your review time.

A short run you will actually repeat

The Daily Recall Run has a 10-question anesthesia core in two sections of five. The first five earn the day, all ten unlock the Daily Chest, and a five-question Bonus Round is optional.

Anesthesia misses come back tomorrow

Miss a question on phenylephrine versus ephedrine or a ventilator waveform, and RecallOS folds that weak spot into an upcoming run with spaced repetition. A good miss today is a concept you own by the weekend.

Turn your own lectures into review

Upload a didactic slide deck, a drug handout, or a photo of your notes and get a summary, study guide, flashcards, a practice quiz, or a concept map — so your program's material becomes active recall, not a PDF you never reopen.

What you get

Daily Recall Run
A 10-question anesthesia core, with streak credit after five and the Daily Chest after ten. Five bonus questions are optional; the core stays free.
Instant rationales
Every question explains itself the moment you answer. Read why succinylcholine is contraindicated or how afterload shifts the pressure-volume loop while the concept is fresh.
Active recall + spaced repetition
Concepts — not single questions — own mastery, and your Recall Score grows as you keep showing up. Weak-spot detection surfaces the anesthesia ideas you have not locked in yet.
Upload your notes and slides
Drop in PDFs, slides, or photos (up to 10 MB) and generate a study guide, flashcards, a practice quiz, or a concept map. One free preview, no signup required.
Panic Mode for exam week
Before a pharmacology or principles block exam, get a time-boxed cram plan that concentrates your limited hours on the highest-yield anesthesia concepts.
Anesthesia streaks worth keeping
Streaks, XP, gems, chests, badges, weekly leaderboards, friend challenges, daily missions, and your Recall DNA keep the daily habit rewarding instead of a chore.

A realistic daily workflow

1Between cases or before your commute, open RecallOS and start the Daily Recall Run — about five minutes across three anesthesia blocks of five questions.
2You take a good miss on the difference between ephedrine and phenylephrine; the instant rationale walks through direct versus indirect action, and the concept is queued for a future run.
3Later, upload this week's pharmacology lecture slides and generate a quick flashcard set and practice quiz from your own program's material.
4With a principles block exam three days out, switch on Panic Mode for a time-boxed plan that focuses your review on hemodynamics and airway.
5Keep your streak alive, climb the weekly league, and watch your Recall Score rise as concepts you kept missing turn into ones you own.

What RecallOS is (and isn't)

RecallOS is a study and practice habit, not a course, a board-prep guarantee, or a substitute for your CRNA program and clinical training. Anesthesia coverage is mapped to published content domains and is educational, not an exhaustive blueprint, and it is not affiliated with or endorsed by the NBCRNA, AANA, or any certifying body. The daily Recall Run is free forever; paid tiers (Recall+ and Recall Pro) exist and any purchase happens through Apple In-App Purchase inside the iOS app — this website is for marketing and the free starter run only.

AI study aid — not medical advice
