Love the app, just don't like the annoying floating purple banner covering the calculation entries as you input. Note: I have a 7.2" smartphone screen too, so it's not phone specific, but by design. I would have given it 5 stars had that been permanent on the bottom. Also, it defaults to 100 units (U-100) even though I base my calculations (more often than not) on .5mL (50 units). Although it appears you can change it, you can't.

Hi Ernest, that purple floating banner is the reason most people use the app. It allows you to adjust the inputs while seeing the impact on your draw amount in real time.
Please reach out with screenshots to hello@supptrack.app. Maybe it looks different on your device. We are happy to update the app to work better for you if this is the case.

No menu, no reset button. Very user unfriendly. To change an amount, you have to go back and delete the inputted boxes, then type the new number. The issue is that in doing it this way, it keeps the error window up (because all fields must be filled out) and won't show the info for that box (such as how many syringes of water to draw) because the "error" is in that box.

Hi Robin.
Please go to the bottom of the Info tab and ensure you are on version 55.2.2. There's a host of new features.
Importantly for you we've added a completely new "reset" function that makes it dead simple to clear the calculator.
We'd love to earn 5 stars from you. Cheers! 🍻

I was going to give it 4 stars. only because I struggled to add 2 different peptide regiments. I emailed support and Jeremy got back to me within the hour, explained the process. bam. I'm gtg. but, it should be crazy obvious, after saving a peptide. "WANT TO ADD ANOTHER!" There is an option for that but, my issue is- one bottle of bac water for two different peptides. different amounts of bac water. when I clicked to add another peptide, I wasn't able to add a second amount of bac water. :)
