Main issue is that app set up and lists cannot be set up on phone. Need full listing and ability to edit on phone. Will not register for complication on face. Looks pretty inclusive and data entry not difficult. Unable to see full listing of calculators.

Thank you for your feedback.

Indeed, the choice I made was to make this app fully customisable from the Apple Watch. I understand your comment and will take it on consideration for future updates.

Additionally, if you browse to the Favourite section on the Apple Watch, then click on manage, you’ll get the full list of all included tools and formulas and you’ll be able to choose the ones you use the most, so you’ll find them very easily.

Best regards

Useful on Apple Watch

A delightful application which works great on the Apple Watch for medical calculations. I have several iPhone-based medical calculators and it's nice to have this one available for use on the watch. It has a fairly large number of formulas. The interface works well on the Apple Watch.

I paid for this app and when I opened it opens the main page and no options to sign in or see other pages. I wish I could give this app just 1/2 a star.

Developer Response ,

Did you notice that this was an Apple Watch dedicated app?
So if you have an Apple Watch you should just install and launch the app from it. If it doesn’t work don’t hesitate to contact me to explain the problem.
If you don’t have an Apple Watch, you can ask Apple to be reimbursed because the app will be useless.
Best regards
