I would like to see the feature where I could eliminate the tape and have a bigger “total” screen
The calculations are so easy to follow as you work through a list. The ability to produce and store the calculations makes it so much easier. Good app.
I have used adding machine apps on my iPhone for ten years and never liked any of them. This one is perfect! It works like a ten key paper tape machine but it lets me edit a column of numbers to make corrections. Definitely get the upgrade to have 400 lines of numbers. To clear the register double tap the “i” key then tap “clear”. One last time: It’s perfect!
I needed to keep track of my purchases for a discount of X dollars off in a grocery store. I found this app and gave the free version a try. It worked well with minimal training until I hit the max lines in the free version, so I jotted down the total and started a new list. My one complaint about the free version is turning off the click sound is touchy. One has to be FAST to hit the off switch before the banner appears, but I got it on the 3rd try. I figure @ $3 getting the update is worth the investment. I have yet to really give it a real test to see what all it can do. The only reason for not 5 stars is I do not know it well enough to give it maximum stars, but I doubt if anyone using it will be dissappinted. The look and feel of the app is very well thought out.
Nice app has a small glitch that prevents you from adjusting the keypad down too the lowest setting though. When you close it out and try Re-opening it again it shows a gap between the minus and plus key.
Does what it claims. A pleasure to use.
Has all I need @ the end of the day Get my totals the email them to everyone that needs them. Have one on each of my devices and the files have saved me more than once. Love this app.
This is a great ten key logic app. Does just what I want, and the tape is a great advantage over other calculators. I do wish they would add a square root feature, but I understand that is not usually on a ten key adding machine.
Very helpful for when I’m away from my adding machine.
One of my most used apps. Very handy and user friendly.
