Ratings and Reviews
Still the best!
I am also a client/user since the PalmPilot days. This new version, despite having some drawbacks, like having to sign on (as many people have pointed out), layout changes, unable to reorganize templates as one would wish, and other minor interface issues, I firmly believe this is still the best analytical/computational application available. I like the ability to sync across platforms and be able to use on my desktop. I also appreciate them keeping the old version around, since that is my preferred app and will use it until my phone no longer supports it.
Update: Just found out original app is not going away. Whew! Thank you!
I am concerned that I now have to create an account to use the app I’ve already purchased. I don’t want my calculators in the cloud. I don’t want to remember another login. Sure some will like it’s enhanced features but I do not. I don’t like that the new nature of using this app takes me from app owner to an unwilling member of your community. My reasons mainly revolve around privacy. I enjoy the app so please don’t FORCE me to signup to use the very app I’ve already paid for. Additional cost or not.
Thanks for updating your review. Let me be as clear as I can:
- Version 4, the previous version, is exactly the same. Nothing has changed about it. You do not need to create an account to use it and you can continue to use it for as long as it will run on your current and new devices. We removed it from sale and are no longer updating it but you can always download the last released version from your previous purchases.
- Version 5, the new version, is a completely separate application. You can choose to download and use it or not. It does require an account to use it as we added features that require an account, including syncing across your devices and access to a web version. Once you log in once it remembers you (in Apple's secure keychain) so you only should have to enter your account once.
I understand your concerns and appreciate that you would prefer not to create an account. That's exactly why we gave you the choice of using the new version or sticking with the old one.
Spent time getting templates....lost after update
Sticking with the tried-and-true original version (together with the DEWALT tools app). At a minimum, I don’t lose templates I spent about an hour researching and downloading to my device’s library for use only to find them gone after an update, and MOST IMPORTANTLY, I don’t have to manage just one more login...to use a calculator!
Yep, stick with the old version. Too many software companies push online accounts and subscription models to use a good (or more correctly ‘what was’ good) apps. Instead, innovate and release stellar updates over a 6-18 month timeframe and I’ll gladly pay you another few bucks. I’m sure others would as well.
