It saved me hours of homework time. Obviously you should learn the dosage formulas but once you do know how to do the math this app will save you time. It can be confusing to use at times but once you get the hang of it, it’s amazing!! 0.99 cents WELL SPENT!! HIGHLY RECOMMEND!! ### 2/5 — Paywall for app to be useable *2021-01-06, version 2.4.3* Can’t even see if the app works well without paying for it... no thanks- I still have a free calculator app... ### 4/5 — Good App *2019-10-19, version 2.4.3* Yeah, they should be up front about the cost right from the get go it is in the description, but for a whopping wallet breaking $0.99, I rolled the dice and am not disappointed yet. Solid app thus far. Would recommend. Quit being so salty and thank you for your service. ### 4/5 — Simple Down and Dirty Calc app *2019-10-10, version 2.4.3* In App purchase clearly marked in app discription. I was expecting more money than 0.99 . App is super simple and super functional. ### 4/5 — RN-ER *2017-04-30, version 2.4.2* Very helpful ### 1/5 — Not free at all!! Won't work without paying *2016-05-13, version 2.4.2* The app will not work unless you pay. All it lets you do is punch in the values, won't calculate a thing without paying. Would have much appreciated them being upfront with the cost. Instead I'll purchase another app just for wasting my time. ### 5/5 — You are the Best *2016-03-16, version 2.4.2* Tnx ### 4/5 — Drop Factor *2016-02-25, version 2.4.2* I use this app every week. I just found 1 error. On the Drop factor says drop/min but this is incorrect. If you look in one IV bag set the correct way is drop/ml. For example if the set says 10 drops/ml, this indicate that for every 10 drops you administered 1 ml. ### 4/5 — Nice App, One Problem *2015-12-12, version 2.4.1* Great app, except that when you enter information in on the gravity side, the keyboard will not disappear to be able to get your calculation. That seems to be the only problem I have found so far. ### 5/5 — CCEMTP *2015-08-20, version 1.2* Works great! ## Most critical reviews (10 lowest-rated) ### 1/5 — Math incorrect *2023-01-22, version 2.4.3* The math is not right ### 1/5 — Locked unless you pay *2022-01-27, version 2.4.3* I would be fine with paying the 99 cents to use it but be upfront about it. ### 1/5 — Disappointed *2020-08-26, version 2.4.3* If you have a charge for the basic app say it up front. Don’t make it impossible to use after it’s been downloaded for even the first screen. Deleted immediately. ### 1/5 — Don’t purchase. Calculations not correct *2020-07-30, version 2.4.3* Bought this in hopes to calculate drip rates for IV medications when programming them into my transport IV pump for work. The math is not correct. Do no buy. I just got scammed out of my money. ### 1/5 — You have to pay before you try it *2019-08-20, version 2.4.3* You can download it but it won’t let u do anything until u pay. Pay for something before hand without knowing is going to work? No thanks ### 1/5 — Might kill someone *2018-08-22, version 2.4.3* Sooo has nobody else noticed that the gravity side doesnt have a drip rate input? It has drop/min but no drop/ml. I think thats what its actually calculating for in that box but it makes me wonder what else is mislabeled. Mislabeling functions in a medical calculation app is a great way to get people killed. USE AT YOUR OWN RISK Or just dont use it :-/ ### 1/5 — Bait and switch? *2017-12-17, version 2.4.3* Guess I can’t call it that since they don’t try to get you to buy something else, but they should just put the price up front instead of trying to scam you. I’ll look elsewhere. ### 1/5 — Doesn't work unless you pay for it *2017-07-19, version 2.4.2* You can put in all the data you need, but when you hit calculate you're told you need to pay. When you try to purchase it, you get an error saying "Purchase/Restore Fail" so this app is completely broken. ### 1/5 — Bad app *2017-04-01, version 2.4.2* Not free at all. Can't calculate unless you pay. Just tell me upfront how much it costs. Deleted app. ### 1/5 — Shady app practice. *2017-03-27, version 2.4.2* Listing as free then requires purchase to "unlock" the calculations. There are better apps for the cost. ## Most praised reviews (10 highest-rated) ### 5/5 — Best calculator for iv *2023-02-03, version 2.4.3* Very self explanatory and very easy to understand and use ### 5/5 — MUST HAVE *2022-01-29, version 2.4.3* Simple, quick, easy to use! A must have for all that titrate meds. ### 5/5 — Simple and easy to use *2020-11-22, version 2.4.3* Flight nurse/medic and use this to check dosages on my pump along with push doses if needed. Costs a dollar which is worth the cognitive offloading that it provides. ### 5/5 — Great app *2020-10-14, version 2.4.3* I was looking for a good app for those 3am critical care transports, and this is it! Reading the reviews, they HAVE updated the gravity portion to add a gtts/ml, so ignore that one. Also, it’s a whopping 99-cents. I know, you have to actually PAY the dollar to utilize an app that someone spent their time to produce to make my job easier. Hell I’ve spent more crushing candies than this app costs! ### 5/5 — Awesome app *2020-01-01, version 2.4.3* Nicely done ### 5/5 — Does what I want. *2018-09-23, version 2.4.3* Pleased with this app. Good value for concise drip rate info. I’m a CRNA and recommend this app. ### 5/5 — Works great *2018-02-25, version 2.4.3* Works correct every time ### 5/5 — First day with it *2016-11-10, version 2.4.2* And can't put it down! Man this is handy calculating medical tool. Put down more list of needs future RNs 🏩 ### 5/5 — Simple *2016-09-23, version 2.4.2* Love it ### 5/5 — Use this often *2016-05-28, version 2.4.2* Very useful and covers all types of calculations I use. Only had it a month and haven't had any issues with it yet. Feel like it was very worth the money! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
