Means I can’t tell which box I’ve ticked or whether I’ve entered the correct weight etc. ## Most critical reviews (10 lowest-rated) ### 1/5 — I don’t trust this app *2025-09-25, version 1.05* I should make an app myself. This is very inaccurate. ### 1/5 — Needs to be fixed *2023-11-25, version 1.05* This is a great and much needed app. However, it has one major flaw: the lb vs kg screen. It should just use one of them for everybody. Because of that screen, which I thought I had set to lbs, I overdosed a patient. Thankfully nothing bad happened. I cannot in good conscience give more than one star to the app, as ling as that screen is not fixed. Local anesthetic systemic toxicity is a killer. Many thanks to both authors. Your work is highly appreciated. ### 1/5 — Update to support dark mode *2020-06-25, version 1.04* Please support dark mode in iOS. When the phone is in dark mode, all the clickable text and entered text appears white on a white background (I.e invisible). ### 2/5 — No naropin in left over *2026-03-20, version 1.05* There’s no naropin on the final left over medication list… also doesn’t tell you when you’re overdosing medications. No updates on this app for over 5 years… ### 2/5 — Has potential *2025-01-20, version 1.05* This could be so useful if they changed a few things around. Add in the hard stops and correct additive formulas ### 2/5 — Would be 5/5 but *2023-04-12, version 1.05* The app doesn’t take into account the hard stop maximums for dosing. Ex: bupivacaine not to exceed 175 mg no matter their weight, or any other local anesthetic, the app does not inform you if you are given a volume over safe dosing limits. Since the whole purpose of the app is to inform you of appropriate safe dosing limits, this really should be addressed or have a notification when above hard stop dosages. ### 2/5 — Incorrect Mixed Dose Calculations *2022-10-21, version 1.05* The app is great in theory, but when you are mixing locals the max should be additive, which is not the way it shows up when you select 2 different locals. For example, in a 70kg pt your max of 0.5% bupiv is 35cc, and with 1% Lido your max is also 35cc, but when using both, your MAX is still 35cc. The app gives the impression that you can give 70cc when using this combo (stating 35cc each), which is not correct. ### 2/5 — Change the color of the text! *2020-06-14, version 1.04* Text is in white, making it very difficult to read. Otherwise, this is a fantastic resource. Please fix above immediately!! ### 2/5 — Text in white... *2020-05-24, version 1.04* Text is in white unable to see what I’m typing. Please fix! Hoping this will be a great tool for school! ### 3/5 — Incomplete *2025-09-18, version 1.05* Locals should be additive. Beware overdosing. Also, needs more local anesthetic concentrations. There’s no lidocaine 2%. Also the app only calculates the leftover bupibicaine for the surgeon as 0.25 %. Half percent isn’t calculated. ## Most praised reviews (9 highest-rated) ### 5/5 — Easy to use at bedside, crucial info at right time *2019-08-30* Really fills a clinical need, few of us have time to do calculations in busy block rooms or in OR, office locations where large volumes of mixed of often used. Super easy to use ### 4/5 — Add 0.5% bupivacaine *2024-07-11, version 1.05* Need to add 0.5% for surgeons preference at end. Only lists 0.25%, so I’ve been halving the remaining total listed. ### 4/5 — dark mode broken *2020-01-27, version 1.04* latest update makes disappear in dark mode. otherwise 5 stars ### 4/5 — Exparel *2019-08-30, version 1.03* Great app!! Please add exparel!! ### 4/5 — Exparel? *2019-08-11, version 1.03* Can you add exparel? ### 4/5 — Great app. Pleas include mg totals *2019-02-04, version 1.02* Excellent app. Mg totals please ### 3/5 — Dental anesthesia *2024-11-08, version 1.05* As a dentist I would like to see articaine and prilocaine reviewed also. ### 3/5 — Doesn't work on iPhone dark display setting *2020-06-20, version 1.04* Type disappears in iPhone "dark" display setting- unusable. Works fine in "light" display. Otherwise a great app ### 3/5 — Unable to view text *2020-04-05, version 1.04* Text is in white so you can see what you are inputting Difficult to use because of this --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
