Finally-A-Great-App ,

Great app

I’ve been using PowerOne for many years now. I was in need of a good RPN calculator and liked their version 4 design. So I took a good look at the rest of the app and discovered the templates. What a discovery it turned out to be too. I’ve spent a lot of time and money on programmable calculators over the years and never found any that worked out. Until now, PowerOne is the definition of programmable, customizable what ever you want to call it. It’s just a lot fun to play around with and when you are done playing you have a powerful tool with you. It is too bad PowerOne is stuck in the calculator section of the App Store. It’s so much more than just a calculator. Although it does have a great calculator. However that’s just a small part of what PowerOne really is.

In Version 6 they brought back Version 4’s interface which was very easy to use and Version 6 is a lot easier to program than Version 4 was, so now we have the best of both versions.

I never had a problem with the login. Because I know what I’m getting in return. Things only a login can provide, syncing across all my devices, and a web based editor. Plus there are things coming in future versions I don’t even know about yet.

Pricing, I don’t understand how you can make money at a 1 time 5 dollar fee. It turns out you can’t. So if we want to keep using PowerOne the developer needs to get paid. The complainers have no idea of what they have. I do, and I’m willing to pay for it.

Subscription

Subscription services are lucrative for developers, I guess. But, for the user I have to decide which apps to subscribe to (if any) and which ones I have to quit using because I can’t afford a subscription for every app I use. I don’t mind buying an app at all, but having to pay an annual fee is just beyond my means. And so, I will switch my "calculator" app to something else other than PowerOne because they, at some point, will go to the next version (x.x or y.x or whatever) and I will be left in the dust having to subscribe to keep up with the technology. If every developer ends up with subscription requirements I will just have to abandon my support for them all. How many $50, $20, $75, $20, $40, $20, $25 services can you afford? For me it’s not many and so I just stop using an app that thinks their product should charge me a monthly or annual fee to use it!! There are plenty of alternatives out there. The smart developer will appreciate their customer’s PURCHASE of an app and take into consideration that users will have to decide which apps to keep or which apps to abandon. The less used apps I have will be the first to go. And, PowerOne falls into that category as there are many alternatives that don’t require a subscription fee after purchase.

I’ve paid enough for the prior versions of this app, remove ads. etc.

I’m done.

Developer Response ,

Hi Wdav,

I appreciate your position. I do want you to know that most of PowerOne is free to use. We include most of the templates and the entire calculator at no charge. We also now keep your templates and some of your calculations synced across devices and make a web version available to you when at your desk, all free.

We do have some premium features, and we do ask people to pay for those. But there is nothing that keeps you from using the free version forever.

Given that and given app economics, it has become clear that a subscription is the only way for PowerOne calculator to survive. We have purposely chosen not to use the kinds of intrusive and dirty tricks that other apps use. There are no ads, we don't sell our customer's data.

Hope you will continue using PowerOne.

Great app! Always making it better... but... there’s the minus “-“ quirk

This is by far the best calculator app there is. Plus the versatility. But, there are always few little things and bugs to squash. There is an annoying thing about how it works after a result shows, if you press the “+” or the “*”, “/“ it will, obviously, invoque the “last” result plus the new operator pressed and it will let you continue with the operation, as expected, but if you press the “-“ it won’t apply that to the “last” but will start as a new operation. The other thing is that when you open a menu it constantly changes its height to accommodate the content. It cool, but it annoys the eye, but in this case, maybe it is just me. But trust me, this is the one and only calculator to have!

Hi Beny!

Thanks for the generally positive review. I did want to make sure you knew, though: the minus sign not invoking chain calculations is a known bug and will be fixed in the 6.1 release coming soon.
