### 2/5 — Avoid

*2026-03-04*

Don’t be an idiot like me and spend money on a calculator you can easily find elsewhere or just ask AI. This doesn’t even work well and they can’t get wording right. Shocking really.

**Developer response:** Hi Sippleb, sorry to hear you didn't like the app. 
Please let me know any specific feedback for how I can improve the app. 

I'd recommend avoiding AI for this type of calculation since it is remaking the calculator every time you ask which can introduce errors in the calculation. The benefit of a calculator, any calculator, is it is a same function every time. Stay safe out there.

### 5/5 — Easy & Accurate

*2025-12-20*

Love this app! It’s affordable, easy to use and accurate. I love that I can save my peptide calculations for future use.

**Developer response:** Hey Teak05! 
Thanks for the positive feedback :)
Please feel free to suggest any additional features I can add in to make things easier for you.

Thanks!

Been loving this app and appreciate not needing to pay a subscription like all the other ones for the same thing. 

Good little app. Just does its job.

### 1/5 — Can't use .

*2024-06-03*

Useless for my needs. Can only use whole numbers. Need to be able to use 12.67 etc. Please advise, thank you.

**Developer response:** Hey Talia! We just updated the app so you can use decimals now. Tap "custom" and enter whatever number you like.

### 5/5 — Convenient

*2024-05-14*

I use this app daily and I've found it to be pretty accurate and extremely convenient for day-to-day use.

### 1/5 — Waste of money

*2024-05-06*

Waste of  money. No access to add decimal point for the right dosage.

**Developer response:** Hey MF8310! Sorry to hear the app did not live up to your expectations. 
We've updated to include decimal places. Please give it another try and let me know what you think!
