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.
I do not use any other calculator…on my phone or off. This is simply the best. It does way more than what I need for my modest math requirements, but it also is perfect for what I need. Especially love the ability to erase parts of equations if I make a mistake and the conversions capability is superb, too. I’ve used this app for years and will not switch.
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!
