PowerOne calculator

This was a fantastic app in the past — look at all the older reviews — but now charging monthly or annual subscription fee for anything more than 3 calculator functions/templates. I mean it’s still good, but in the end these are all mostly just basic math (spreadsheet) functions. I miss the old pay once for premium approach, otherwise these monthly subscriptions are just too rich for me.

Updated 9/23 - thanks for the quick response. My error not seeing the conversions initially. I did like the old version better but definitely still a usable and convenient app. Sorry for the initial rating. I used to have the app but lost it when I just purchased a new phone. Said app no longer available in App Store, even though I paid for the original. New version does not include the metric conversion tools…I am assuming if I pay $2.99 a month they may be in there, but I’ll never know because I’m not paying for something I already paid for.

This app used to be my favorite calculator app. Now it’s the worst! Do not download this app! It’s extremely frustrating to use and it keeps wanting you to pay for the upgrade!

I understand that developers want to make money and start charging for a new “upgraded” app, but what I cannot abide is when they disable older apps -which, in the case of PowerOne, were far better and more intuitive than the new one- in order to force users to switch to the more profitable app. This is why nowadays the entire Apple AppStore ecosystem is a disgrace for those like me who have been here since day 1.

I have been using this calculator since it was on the Palm Pilot. It’s great. All those HP imitation calculators are also-rans.

I feel this is the best financial (and other) calculator there is. The simplicity of use can’t be beat. I use the Time Value of Money the most, frankly. Running calculations while deciding on investments is invaluable to me. I also use the Revolving Debt and General Loan calculators a lot. I honestly use this calculator almost everyday.

Best all around application!

The new version of this calculator is very impressive. It has a lot of flexibilities added compared to the old version. The user can easily set the arrangement of the functions menu based on their needs. The program writing capabilities have also been made a lot more user friendly. I am glad that it now has the engineering format but unfortunately it is currently ignored when in programming mode.

Will be looking for a new calculator as this one no longer has a dark mode unless you subscribe. Update: Dark mode is back on the free app. I will continue to use. Thank you!

This is a great financial app and so much more. Templates library is extensive. Support is excellent.
