The History Function is Simply Fantastic

Your Calculator app is 100% the absolute best calculator app I have ever used. I have diagnosed ADHD, and trying to keep a budget can be difficult (I have literal notebooks filled with budgets from years of trying - lol). The history function & feature on your app has allowed me to go back when I forget whether I included a bill amount, and verify whether I need to recalculate. It has saved me so much time & money in my many years of using it. Your Calculator app was the first I ever tried on my very first iPad, and I have downloaded it on every iPadOS device since. It changed the way I do all financial calculations. I am just so happy to be able to support this company in any way, even just with the annual subscription to this app. Thank you for designing something simple, practical, and completely functional.

Tired of apps overdoing ads ,

Ads

I switched from Samsung to Apple. It’s been two years and frankly I still miss some features of my Samsung. One of them being the calculator. I run a small business primarily through my phone and regularly need to make multiple calculations with the results I just calculated. My Samsung would let me copy a result and plug it right back in… I greatly miss that feature. I downloaded this app and have found it adequate to meet my needs. There have always been ads and I understand I’m using a free app so ads are how it is funded…. HOWEVER recently the ads have been overwhelming. As soon as I open the calculator remembering the numbers I just read from a different app that I need to calculate there’s ads now with multiple screens I have to click through and they are happening constantly. I have found myself opening the app getting through the ad and then going back to reread the figures to make sure I don’t make a mistake. It’s easily doubling if not tripling the time it should be taking me. At this point it would be quicker for me to go back to the original app and just open a note and record my own history.

Ads are out of control

As other reviews note, the app is well designed and does math as expected. I also use the “ad supported” free version. I’ve been using this app for probably four years. My two concerns prompting me to look for another calculator app is indeed the (clearly getting out of control) advertising assault. I’ve never minded the typical, fairly small bottom of app advertising scroll and -OCCASIONAL- full screen advertising hit that only took one easy to see (X) to close that full page ad to continue. BUT, recent “updates” now have this app an advertising pain. Full page ads are a constant, the “X to close” discretely shaded within the ad, with another right on the heels.

While I understand what free gets me, regarding the “subscription”, one it’s not cheap, and two, RECURRING not cheap is simply a full stop. The terms of service and privacy policy already spell out how much data about me this app collects and obviously resold for company revenue. Just SELL ME THE APP for a reasonable price. And be done with me. A subscription suggests constant new material and varying product. And that would be??
