Comments on io Calculator for Android

★★★★☆ Sisanda Laaibah · Mar 20, 2022
Bottom and space annoying, but it's better than pop up ads but so far so good
★★★★★ Tony Carter · Aug 22, 2021
This calculator is ferry immeasurable ✔👍
★★★★★ King B · Jul 2, 2023
Works exactly like my iphone calculator which is what I wanted!
★★★★★ Keikar Channel · Jul 9, 2024
Really recommended. Not like other calculator that can't hit button = consecutively. This even with history. Like upgraded ios calculator. Really love it to purchase premium
★☆☆☆☆ Ryan Adams · Nov 7, 2020
This app is a waste of time. The calculations just crash my app and there is way too many ads. Also, the description and screenshot are lying because there is no landscape calculations. Wish I could give 0 stars.
★☆☆☆☆ Santo Michael · Nov 19, 2020
The User experience is not good. I tried changing the orientation to use landscape mode and nothing happened. Half of the calculator is cut off the screen. Not worth the download. Waste of my time.
