  1. 1/5Don’t recognize my original purchase of app

    My old phone got wet screen went all black so had to get a new phone and now app says it doesn’t recognize purchase or whatever and now wants me to repurchase but now with a subscription what is that about why would you guys have a subscription for this calculator that would make this calculator super expensive I have a handheld one that I bought before i purchased this app few years ago but that is just a another thing I would have to carry around I’m a welder and having it on the phone was perfect but this subscription is just crazy it’s just a calculator why would would you guys think this is ok to do

  2. 5/5Owner operator

    I owned three of the handheld calculators, one for office, one for truck and one for lunchbox now that I have this calculator on my phone in the easy use of all the features is amazing and I have now given away my other three calculators to my Formen in the field. this app is well worth the money and it’s probably one of the best if not the best app on my phone.

  3. 4/5You must think we’re idiots

    Why would I pay $36 per year when I can buy the actual calculator for fifty dollars and the last one I bought lasted me over ten years as a matter of fact it was working the last time I saw it, it was stolen from my toolbox during a job I was working on point being is you could make the price ten dollars and I’m certain you would make plenty of money from your sales don’t be greedy it’s a great calculator lower the price for the lower class working man and you would most likely prosper in more ways than you can imagine. Thanks

  4. 1/5FRAUDULENT FEES

    Apple will go over your head directly to your credit card company to get payment on an auto renewal without your approval. I had zero interest in resubscribing for this app after finding it useless for my particular job. No fault to the app. My card had expired and I was glad to leave it that way. However, rather than communicate with me, Apple was somehow able to get my credit card company to provide the updated card info without contacting me. This is fraud and I’m sick of it!!!! Dumping Apple and my credit card company after this theft. What a joke! If you want me to renew, ask!

  5. 5/5Great app overpriced tho

    The app works well and is super convenient but the subscription seems a little ridiculous. Your paying the price of a new calculator every year and your only getting software not even hardware also I wouldn’t get a new physical calculator every year it would last a lot longer than that
