  1. 5/5Very simple and easy to use

    I’ve been using a TI-30X IIS for over 10 years now and every time I tried to switch to a calculator app there was always something that I needed that the app couldn’t provide. After trying at least 10 different apps I finally found this one. It allows you to move your cursor to edit an entry anywhere in the line (a surprisingly rare feature) and it allows you to recall former calculations and use the answers to them in future calculations. That combined with a lack of ads and ease of use makes this a fantastic calculator app! My only complaint is that the app tends to give 3 digits in front of the decimal when it is giving you an answer in scientific notation. For most people that is probably fine, but for my work that is annoying. If it either defaulted to 1 digit or allowed you to select how many digits before the decimal in the settings then that would be good.

  2. 5/5Great replacement since Apple broke the Calculator

    I just discovered this since Apple Sequoia broke the paper tape on the calculator that I use frequently. The history on this is attached to the main window instead of being a separate window so if I move it to another desktop I don’t have to move two window.I also just discovered the history on this (that replaces the paper tape) is shared between my desktop Mac Studio and my MacBook Pro. Apple should be watching this developer and realize they have been pwned. Excellent app and worth more than I paid for it. 😉

  3. 5/5Best Calculator App On The Market

    I have tried several calculator apps from the App Store, each of them had issues like having to wait for the add time to expire before being able to access the calculator, to not working with an external keyboard, to intermittently not working with an external keyboard. This app has none of those issues, and I can not say what a time saver the sidebar on it is in terms of looking up the previous total on a calculation without having to redo it to get the total, nothing short of a huge time saver. I love this calculator app, swear by it, and would recommend it to anyone looking for a complete calculator app that cross platforms from the iPhone, to the iPad, to a Mac Desktop.

  4. 5/5Solves is everything the default calculator needed

    I first downloaded solves on my iPad because, well, you know, no iPad calculator app. As soon as I used it for the first time I downloaded it on my phone. Being able to use parentheses and write multiple functions into one problem was a huge time saver and made everything a lot easier. Solves will show you everything you’ve typed and keep a running indication of the answer. No need to hit equals and then start over if you want to add or change something. Yep, don’t forget that, you can edit a number part way through your problem and solved will update the answer using the new number. The history? All laid out in front of you right above the number keys. No need to remember numbers or hope you’re getting it right when you type it back into the problem. You can A) copy directly from history, or B) just type what you see. Sometimes I need two calculators, I have the default calculator and solves right next to each other because I can’t download solves twice. Solves fixed everything that was a problem in the default calculator app. The part I appreciate most? They didn’t try to change the entire UI or look of the app, you can set it up to look just like default app.

  5. 3/5+/- missing or consider upgrade?

    I’ve been using as a replacement for the MacOS calculator due to history/paper tape changes. Unfortunately, one of the keys I need frequently is +/- (which changes a calculation from positive to negative or vice versa). This app doesn’t seem to have that key (and/or it requires an upgrade?). For me it is a pretty basic function. Would appreciate confirmation of whether this is even included in the "solve+" option, though I doubt I would pay extra just for this one key that I use all the time. Will probably need to delete the app and find something else.
