this is trash, had it on my old phone and paid a one time flat fee, now it's a subscription, I'll just buy another physical calculator so that I have one in my truck and one at my desk. It's not right that I made a one time purchase and it can not be transferred to a new device since my old phone broke.

Developer Response

Hi - You do not need to pay again. You just missed a couple of updates which would have made the transfer seamless. Please contact us at techsupport@calculated.com and we will get your original purchase restored.

Pay monthly or annually. No one time purchase. Others exist that work for what I need, but I don't have to pay $5/month or $40/yr.

Developer Response

Thank you for the feedback. We're continuing to upgrade and improve our mobile platform and are adding new innovative features to this App which takes a lot of work from the folks in Carson City, NV, USA. We appreciate your perspective.

my review is more about price than the product. why should I pay for a year to use the app if I can buy the same calculator for basically the same price and have it for much longer paying once? if you offer me to buy the app and pay just once, I would not give this review. It just doesn't make sense. this is not a product that is going to change year after year to justify a subscription model.

Developer Response

Hi Jeff - Thank you for your comments. We appreciate your perspectives. Actually our App developers are continually improving and adding innovative new features to this App that you will not find on the physical calculator. It takes a lot of work from our team here in Carson City Nevada to keep improving these Apps. Why not give a try for 7 days?

I've had either this or the physical calculator for 25 or more years. Hard to imagine life without it in the construction world, pre AI. Even as AI gets better, this calculator holds its own.

Developer Response
