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 ### 4/5 — More syringe options *2025-03-30, version 3.0.0* Love but please add more syringe options like .5ml comfortox! ### 2/5 — No longer working *2024-11-01, version 2.0.3* No longer allowing me to select the syringe, only says no data. ### 4/5 — Please add more syringes *2024-10-22* Love this app since I learn better visually. Would love it if they put other types of syringes especially with a 0.5 of comfortox …yes I know I could use the 0.3 one as a guide but just so much easier to look and compare! ### 4/5 — Hoping for more *2024-10-05* I typically use standard dilution for Botox, but I was hopeful this would help with compounded Semaglutide and tirzepatide dosing. I would love an addition of mg per ml to units. The different strengths of compounded vials because cumbersome in calculating dosages. ### 4/5 — Good tool, need more syringe sizes *2024-09-05, version 2.0.3* This is a great tool when changing syringes. I would love to also see the 0.5ml Comfortox syringes added. ### 3/5 — No TB syringe. *2024-06-25, version 2.0.3* No TB syringe included which is honestly the most important differentiation between the Insulin vs. TB ratios. Add a 1mL TB syringe. ### 1/5 — MD *2024-04-19, version 2.0.2* It’s a practical idea however I am unable to see anything other than semiglutide info. No thankd ### 1/5 — Review *2024-04-19, version 2.0.2* Force closing each time I try to open the app. Only medication that I am able to select is Semaglutide. ## Most critical reviews (10 lowest-rated) ### 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 ! ### 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?? ### 1/5 — Incorrect Syringe *2025-05-03, version 3.0.0* The Comfortox syringe picture is incorrect. What is displayed is a insulin syringe. Please correct this. I have requested this correction > 1 year ago and was told it will get done. Thus far, it has not. ### 1/5 — Syringe options don’t populate making this app worthless *2024-11-02, version 2.0.3* Syringe options don’t populate making this app worthless ### 1/5 — No Syringe Options *2024-11-02, version 2.0.3* Paid for the app but it doesn’t have a drop down menu with any options for syringes. It’s empty with no choices. Useless. ### 1/5 — App not working *2024-11-01, version 2.0.3* I was excited to try this app out so I downloaded it and went right to open it up. After plugging in my units, and reconstitution amount it is not giving me any options of syringes in the dropdown. It just says no options loaded. Save your money! ### 1/5 — Wrong syringe *2024-06-11, version 2.0.3* Listing is NOT a Comfortox syringe, but rather a BD insulin syringe! Please fix! I received a response from your company indicating that you would change this and it does not appear to be. ### 1/5 — Bugs *2024-05-04, version 2.0.2* It still won’t get off of a single drug screen, for me semaglutide. There is no BACK button, and if I press info it just repeatedly shows leave a review window. I’ve uninstalled and reinstalled a couple times. I wish it would work ### 1/5 — Advertisement wont let you complete a calculation. *2024-04-24, version 2.0.2* Semaglutide advertisement will not close so you can complete calculation. ### 1/5 — Unable to use for anything but semaglutide *2024-04-24* I signed up for this app and paid and I could never navigate away from the first page for semaglutide. It appears from the app description you can use this for other injectables. I would never have gotten this and paid for it had I known this. Very misleading. **Developer response:** Hi there, if you click the back button on the top of the screen it will go back to the dilution calculator for nueromodulstors ## Most praised reviews (10 highest-rated) ### 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 ### 5/5 — The app performs as intended *2025-01-14* I don't know why people are giving it low ratings. It has a simple, basic, and user-friendly interface. I use it for botulinum toxin dosing. It's very practical. ### 5/5 — Super helpful *2025-01-11* Very helpful app **Developer response:** Thank you so much for your review :) ### 5/5 — Physician *2024-04-21* This is a great little APP. I recommend it to my students when I do trainings. I wish I could offer them a discount or free trial. **Developer response:** ### 5/5 — Working again-best app! *2024-04-18* I can't figure out how to delete my other review saying the app wasn't working but it is back and the best app I could ever recommend to injectors in the field! **Developer response:** Hi there, thank you for editing your review as we went through that small issue with the app. ### 5/5 — App is crashing *2024-04-17* I love this app and use it very frequently but it isn’t working since the addition of Semaglutide dosing. Please help. **Developer response:** Please delete and re install the app. I’m sorry for the inconvenience ### 5/5 — Great *2024-04-16, version 2.0* Also refer back to this app. Love it!!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
