No longer works

I used to use this app often for tox calculations. So many changes have been made, it no longer does that. Have deleted, reloaded, updated. It no longer works !

Great app; have one suggestion!

**Update! This was quickly added :) thanks!!**

I really like this app, but I would love to be able to enter the number of units for a tox and have it show exactly where to pull that on the syringe. For example: if I use a 1.2mL dilution for Daxxi, and want to pull 14 units, where is that line on the syringe? Thanks!

Response from developer

Hi Elise, i have added that functionality. Restart your app and it should update.

App Has Been Revised

The developer reached out to me and we were able to get the 0.5mL Unitox syringe back and it is now correct for utilizing standard 2.5mL dilution. Thanks for the quick app update. We love utilizing this for all of our Tox needs!
