I also really like how you can add multiple LA to the max dosage calculator. ### 5/5 — Anesthesia Treasure Trove! *2026-05-07* Great app with lots of data and information regarding anesthestic care, comorbidities, and surgical procedures. Also lots of cool tools to create plans and keep track of cases, emergencies, and more! ### 1/5 — App does not open *2026-04-18* I’ve tried several times to open the, after this most recent update and the screen is frozen. **Developer response:** Hello, Thank you for using Follie! Some users have had this issue due to their specific devices with the large update. This seems to be resolved after deleting and redownloading the app. Please reach out to us if you continue having this issue or encounter any others! ### 5/5 — Super helpful *2026-04-17* Will definitely be incorporating this into my practice! Great app and super helpful. ### 5/5 — AMAZING! *2026-04-16* I can’t give this app enough five stars! Even more so the creator of the app! Initially I actually requested a refund because some of the material felt incomplete. He asked for feedback and fixed everything that I was concerned about I am thrilled! It really is an end all be all tool and I highly recommend it to anyone especially anesthesia students! ### 4/5 — Only Complaint…Doesn’t cross devices *2026-04-07* Really wish I could log in and get access to care plans I made between devices. I have faith that this will occur when the log in feature is activated in future updates. Otherwise, absolutely incredible and useful! Cut planning time in 1/2 easily with access to calculators, surgery info, etc. It’s Vargo on crack! Don’t pass it up. **Developer response:** Thank you for your feedback and for using Follie! You are correct about the log in feature! Enabling and managing accounts on the app takes a little extra time to ensure your data (email/password) is handled securely. This level of update also needs to be reviewed by Apple, which can take up to a week, and be beta tested to ensure there are no significant bugs. Once accounts are up, users will be able to sync across devices. This, and more, will be available in a significant update hopefully sometime this month. If there is anything else that you wish was in the app, please contact me on Instagram @follieanesthesia or email attunedlabs@gmail.com, and I’ll be happy to add it! Thanks again! ### 5/5 — BETTER THAN THE REST *2026-04-05* Literally such a cool app! Have had vargo in the past but this is much better looking and also more all inclusive. Would recommend for any anesthesia provider looking to improve their quality of care. The EKGs being animated is sick btw! ### 5/5 — Better than Vargo *2026-04-04* I’ve tried a few apps including Vargo and I can confidently say Follie stands out in almost every way. ### 5/5 — Very helpful!! *2026-04-04* This is a great, very updated resource for anesthesia providers! Easy to use. It has everything you need and nothing you don’t! ### 5/5 — GREAT ANESTHESIA TOOL *2026-04-04* This is one of the most practical and well-designed anesthesia apps I’ve used. You can tell it was created by someone who truly understands real-world workflow in the OR. The emergency protocols, drug references, and case planning tools are all organized in a way that’s actually usable under pressure—not just theoretical. What stands out most is how intuitive everything is. It saves time, reduces cognitive load, and puts key information exactly where you need it. I’ve noticed some negative reviews that seem unrelated to the app’s actual functionality. From a purely clinical and usability standpoint, this tool is extremely valuable regardless of who created it. If you’re evaluating it based on performance, it absolutely delivers. Highly recommend for anyone in anesthesia looking for a reliable, efficient reference. ## Frequently asked questions about Follie ### What is Follie?
