Doesn’t include all functionality of website

This app is really nicely done, but, it’s missing things like “weekday only” calculations and other niceties that’s on their completely free website.

Hope they can add those features, which would make this, easily, a 5-Star app.

Developer Response ,

Thanks for your review. We plan to expand the app with more calculators if the app proves to be a success.

It’s Great When It Works

I have used this app for some time and find it a tremendous asset when it works properly. It hasn’t worked correctly since IOS 12 was released. The search option doesn’t display character input. The app still performs a search, but the field is blank and search results are inaccurate. I have submitted this issue in feedback several times, but it remains an issue.

Thank you for your input. A new release is scheduled for the very near future which should handle this issue. Please check back later and update your rating/review.

Stick with Their Website

Website is easier and has more features. For example, if you want to add to the current date and time, the website makes it very easy to tap a link and set the current time, but this app makes you scroll through the hours and minutes since Noon, i.e. it doesn’t default to the current time. The website also has a ton of additional options/features.

Developer Response ,

Thank you for your input. We are glad you like the website, but as you have found out, the website and the app are two different things. We suggest you continue to use the website if you prefer it but in future rate the app for what it is, rather than what it is not.
