### 1/5 — No longer works

*2026-02-01, version 6.0.0*

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 !

### 5/5 — Great app; have one suggestion!

*2025-09-08*

**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!

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

### 5/5 — Life saver

*2025-08-30, version 3.0.2*

Absolutely love this app, greatest invention ever

### 5/5 — Great app; have one suggestion!

*2025-08-30*

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!

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

### 5/5 — App Has Been Revised

*2025-08-14*

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!

**Developer response:** Hi there I will add it asap. Also what do you mean the units are off? Can you email me benningkeaton@gmail.com

### 3/5 — New to app

*2025-06-26*

I am new to the app and whilst it’s helpful with syringe u can not see somewhere to choose which allergen you are using eg Botox, Bocouture Azzalure for the units to ‘correct ‘

**Developer response:** Hi, there is no need to enter in the brand name. Just enter in the reconstitution numbers and the calculator will do the rest. For instance, both brands you named use the same reconstitution numbers, while Dysport would use different numbers. The design of the app is purposely built to be used across all brands, just by using the numbers provided on the vials! Please feel free to contact us if you need assistance, we would be more than happy to help :)

### 3/5 — Disappointed

*2025-06-05, version 3.0.1*

Great app but some pictures of syringes are not helpful if you can’t read the numbers especially the .50 ml syringe

### 2/5 — Will not give tox options

*2025-05-29, version 3.0.1*

This app does not give you the option of dysport / botox/ etc . Dysport dilution is different. 
So not a very useful app. 
Dilute 2.5cc with your 100 Unit tox and you’ll have 40 Units in a 100 unit syringe (1.0cc) Or 20 units in a 0.5 Syringe . You’re welcome !

### 3/5 — Syringe selection

*2025-05-11, version 3.0.1*

The app doesn’t have Comfortox syringes listed as an option for use with toxin dilution

### 1/5 — Syringes

*2025-05-09, version 3.0.1*

What happened to the comfortox syringes?? These are what most of us are using, the .3 and the .5??
