Ratings and Reviews
I searched and searched for a decent calculator for my Apple Watch. After deliberating the cost, I finally went for this one. It has the features I need/want, and works pretty well. I like the haptics feedback when typing. For some reason, I couldn’t add the complication to my watch face from the phone app, so I had to do it on my watch. It took me a bit of time to figure out how this app works, but I think it’ll be easy and fast to use with time/practice.
The only Calculator I’ll use
Have been using this calc for years and the only one for many reasons.
Most calculators don’t give me the option to see what I’m actually pressing. I like to see my numbers and not just the total.
Plus, I love the interface. Stunning and easy to use!
Ugh I just want to do math
I have used this calculator for a number of years. However the most recent update throws up a dialogue that I’m supposed to swipe down to close but it doesn’t close and now I can’t do any kind of math to save my life!
I received a dev response email today. I can’t tell who is being lame here. iIs it Apple because I only received the email about the developer response today, Oct. 2018? Or is it the developer because they somehow backdated their response, which is dated the day after I posted this review. I suspect it’s both! And restarting the app I didn’t help! You had a bad update own it!
