Perfect replacement as I just use it to pay bills/ balance checking account. I don’t do any fancy functions with it ### 5/5 — WENT BACK TO IPHONE FOR THIS APP! *2020-09-10, version 6.20ku* I went back to an iPhone because I couldn’t get this app on Android. I’m a bookkeeper and cannot live without this app!!! Love it, look no further, you have found the best! ### 5/5 — BEST THERE IS! *2020-04-08, version 6.20ku* I can not say enough good about this app. I have always used a printing calculator, I finally found an app that I am comfortable with! Do not hesitated, you will wish you had found this sooner. I cannot find a single negative, or thing that I would change. Thank you! ### 5/5 — Easy to use *2020-03-31, version 6.20ku* So great to have a “real” adding machine. ### 5/5 — Great *2020-02-07, version 6.20ku* Great app! ### 5/5 — Works better than any adding machine *2019-11-09, version 6.20ku* The ability to save the additions to file and export calculations to a spreadsheet is a nice touch. This is the real deal app. Worth purchasing! ### 5/5 — Great calculator for business deposits *2019-09-07, version 6.20ku* Very useful to be able to emulate an adding machine with a tape record to review. ### 5/5 — LOVE THIS APP *2019-06-03, version 6.20ku* I’ve used this app for many years. I absolutely love it. It’s perfect for my simple needs. Easy to use and understand. I highly recommend this app. Perfect and easy to use!!!! ### 5/5 — Great! *2018-10-24, version 6.14ku* I love this calculator. Good stuff! A must buy! ### 5/5 — Great app *2018-09-28, version 6.14ku* Using this app, I can add long lines of numbers total it up, find errors, make line corrections and work with more then one long succession of numbers at a time. I do my finances the old fashioned way and this calculator handle all my problems. I recommend it if you deal with multiple sets of numbers! ## Most critical reviews (10 lowest-rated) ### 1/5 — outdated and no support *2026-03-21, version 7.10ku* could not save taped,nor export results. Doesn’t work for new iPad ### 1/5 — It does not subtract *2022-11-08, version 6.20ku* I can add perfectly…BUT THIS DOES NOT SUBTRACT !!! It only adds when I tried to subtract!! I’m so ticked off I want my money back ### 1/5 — Annoyed *2018-05-24, version 6.14ku* While the app itself is good, EVERY TIME I open it it pops up the review screen...I rarely write reviews so I click “don’t ask again” ...which DOES NOT DO WHAT IT SAYS. So now because of that I AM writing one. Fix this issue ### 4/5 — OK with a couple of annoyances. *2025-12-10, version 7.10ku* In fixed+ mode, the total only shows digits after the decimal that aren't zero. Also, on iphone the method to clear the tape is ridiculous. ### 4/5 — Works well except for one thing *2025-10-17* The method to clear the tape is ridiculous. ### 4/5 — Only thing from 5 ⭐️ is iCloud sync *2022-09-26, version 6.20ku* Great app. Easy to learn, especially if you know 10 key. Can keep several lists saved. However, no way to do handoff due to lack of iCloud syncing. ### 4/5 — Good app but some keys appear not to function *2022-09-22* First of all this is a great app for adding big columns of figures. The ability to edit the tape and email the tape is perfect. There is a % key on top right of keypad but it does not appear to do anything and nothing in the guide to say what it does. Likewise the +/- key seems to be inoperative. I searched the info and find a button at the bottom marked “see index”, that doesn’t do anything either. Perhaps they all work and I am not using it correctly, in which case it needs more complete instruction. **Developer response:** Thank you for the positive feedback. To clarify this App, it is an accurate 10 Key Adding Machine like a Casio, Sharp or Canon found in a stationary store. Percents in a 10 Key Adding Machine are performed like this example which adds 6% of 30000 to 30000: <30000 X 6 % +>: The result will be 31800. You can do a search on the web for [www.tenKeyCalculators.com] for tutorials. Thank you ### 4/5 — Great App *2022-08-30, version 6.20ku* I'm so used to using a calculator with a tape I was pleasantly surprised when I found this. I love the fact that I can go back & review what I entered and check for mistakes (and I make them all the time.) It's really a great app. Thanks ### 4/5 — Does what it says it does! *2022-07-05, version 6.20ku* Works the way it should. Definitely the best ‘adding machine’ app I’ve found to use on the ipad! ### 4/5 — Adding machine *2019-06-22, version 6.20ku* Love the ease of use and ability to save product. Very intuitive! ## Most praised reviews (10 highest-rated) ### 5/5 — Manager *2026-03-14, version 7.10ku* Very easy to use and it is amazing. ### 5/5 — As close as you can get to an adding machine *2026-02-12, version 7.10ku* This App works very well, perfect for balancing your check book and adding long spread sheets. ### 5/5 — Great app *2026-02-07, version 7.10ku* This acts just like the old physical 10-key machines. There was a slight learning curve because I haven’t used a 10-key for 20 years or more. But the app works really well. It’s certainly worth the price. ### 5/5 — Adding Machine not a calculator *2025-09-15, version 7.10ku* The tape feature makes it easy to check and retain your work. Second, it is an adding machine. Enter the number then the operation much easier if you think that way ### 5/5 — Old School *2025-02-15, version 7.10ku* Sometimes an old school adding machine is just better than a calculator! ### 5/5 — Great app *2024-05-26, version 7.10ku* Use it all the time. ### 5/5 — Best app I have! *2024-01-31, version 7.10ku* This app has revolutionized my job! Easy to use, with a quick help button if you forget. Fix a mistake with ease. Totals each page/section and gives a grand total if needed. Print from my printer! Can’t say enough!!! ### 5/5 — Wrench Spinner *2023-09-06, version 6.20ku* I like this calculator app for the “paper tape”. The paper tape allows one to check not only the value entered but the operand applied to the value. ### 5/5 — Great app *2022-07-13, version 6.20ku* Use it all the time. **Developer response:** I have not received any communications. Please try again. Thank you. ### 5/5 — Great app *2021-08-24, version 6.20ku* Works like a 10 key --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
