Calculator ‪+‬ 4+

Update from old review. I’ve been using this for probably about 8 years. It helped me all throughout high school and though I don’t use as frequently in college, it is still great for daily use and the occasional assignment that requires it. UI is very intuitive and it is quite feature rich. Definitely worth paying for.

Old review:

I’ve been using this for all 4 years of high school, and it’s been great. I haven’t paid for the extra functions, and I might eventually, but it’s much cheaper, and just as effective as a Texas Instrument calculator you’d pay over $100 for. The interface takes a second to get used to, but it’s more intuitive than your average calculator. I definitely recommend this.

Por muchos años he utilizado esta aplicación de calculadora y nunca me ha fallado. Fue mi preferida por encima de cualquier aplicación o calculadora física. El problema es que ahora todo el mundo quiere hacer de cualquier cosa un servicio pago. Con eso, por lo regular, no hay problema, el problema que tengo es que cada vez que voy a utilizarla ya no voy directo a la calculadora como antes, ahora tengo que hacer de 2 a 3 pasos para entonces poder usarla. La intuitividad se perdió, la facilidad y conveniencia también. Encima de eso, ¿ahora tengo que pagar para no tener los malditos anuncios? ¡Creo que no! De verdad, muchas gracias por todos estos años de servicio que me has brindado, pero llegó el momento de cambiar.

For many years, I have used this calculator app and it has never failed me. It was my favorite above any other app or physical calculator. The problem is that now everyone wants to turn everything into a paid service. While that usually isn't a problem, the issue I have is that every time I go to use it, I don't go directly to the calculator like before; now I have to go through 2 to 3 steps before I can use it. The intuitiveness is lost, as well as the ease and convenience. On top of that, now I have to pay to get rid of the darn ads? I don't think so! Truly, thank you very much for all these years of service you have provided me, but it's time for a change.

This app was my favorite calculator for years, through college and into the workforce. I paid to buy the premium calculator years ago, and it was labeled as a one time price to get a great scientific/graphing calculator. I have loved and bragged about this calculator. My spouse uses it as well.

In a recent update, this calculator has suddenly and significantly changed. I’m being told I need to subscribe to get a calculator I already bought a lifetime license for? And I have to click around multiple times to get to functions that used to be at my fingertips. I noticed the “color themes” example images still use the old layout, so I grabbed a screenshot. The old layout is much better! Why are parentheses and fractions now hidden?? And the “copy” button no longer results in my copied data being visible on screen… I have to go paste it somewhere to see it. This is a significant decrease in functionality, while also being told I need to pay more?? For what used to be an 11/10 calculator. I’m so frustrated.
