Critical Customer Insights

1. You have to count the number of characters so if it's set at 0.5 you have to hit delete key 3 times (but nothing on screen changes) then type in desired dose (but nothing changes) then advance 2 C changes.Best App on the market! This helps with calcs, great refreshers, breaks everything down, overall 10/10.

2. However, it doesn't allow me to change weights for weight based infusions.Drip slider doesn't change flow rate and RSI crashing.

3. The same effort needs to be put into clinical facets as was to design aspects.Ground critical care transport & fixed wing flight nurse.

4. Example 1.5, 2.5, 3.5.... not 1, 2, 3... I'm using Android latest OS as of today, 11/14/2021, & when you place cursor in dose area to type the original dose stays there so you can't see what you're typing until you hit done.

5. 2) The critical care drip calculator user interface is wonky-the cursor isn't visible when enteringSlider for changing dosages keeps the ".5" and never zeros.

6. It is a good idea in principle, but none of the weight-dependent doses update for any change in reported weight.

7. Complete waste of money due to poor stability on Android.I'm just getting into this app but your example for A-fib is actually A-flutter... I've only looked at about 4 things in the app so I'm sure there's probably some other stuff that was over looked.

8. If you delete backspace over the weight to clear it, you can't type it back in.I love the app because it contains so much information.

9. I contacted the developers and they were great about emailing me back and ultimately fixed the issue.

10. Also, there is s field for kg, you can edit that field and change the kg, but if you delete that field, you can't add anything.

11. Setting the weights are difficult for weight based dosing.
