Upon opening, learned there's a 3 day free trial and then $15 per week for "premium." PER WEEK! That's almost $800 a year! 😂 Not looking to support a cash-grab. Pricing is an absolute joke for what the app offers. I did get a good laugh at the developer responding to reviews basically saying "sorry you're too poor for our app" though, very entertaining. - **1★ · February 6, 2025** — Free trial, but you have to set up payment method. Edit: It's a calculator. There shouldn't need to be any premium version. And also, you shouldn't need to get a payment method if someone only wants to use the free part. Remove the scummy parts and I'll give it a better rating. Edit edit: wow, you guys are missing the point. Don't ask for any payment method until someone chooses to upgrade. Don't make me register and provide a payment method when I open the app. So scammy, so obtuse - **1★ · March 3, 2025** — All I wanted was to download a calculator on my Samsung. What was supposed to be a quick calculation turned into 5 minutes of advertisements as every time you switch to a different app, when you return there's an ad. While I was trying to do the calculation on this app, my wife did it on a piece of paper in half the time. If you are going to charge for... a calculator app? At least make the very first free experience a more pleasant one. 0/10 recommend. ## About Scientific Calculator With History - The Perfect Tool for Every Math Lover!
