Ratings and Reviews
Best I have found but a bit buggy
I agree with others that there are some bugs and often it takes opening it more than once for it to work. Sometimes the app doesnt respond to touch and makes it more frustrating. I used on a 6s+, 7+ and iPad Pro (9.7 & 10.5) so I assume its not the device.
I was looking for an HP that has the Solve function they pioneered yesrs ago (e.g. on the HP-28 and many others). Used to be great and easy to use but as the calculators got more sophisticated (HP-48/49) it became less easy. Its a bit easier here but not great. I suppose I'm looking looking for is long gone and the HP-28S experience is dead. I will keep looking but until then I will use this app.
Latest Version of Calculator Keeps on Crashing
This was a great app, but the latest version has significant issues and has become unusable. It constantly crashes when you use any of the CAS solve capability. I tried deleting the app and re-installing, but that did not correct the problem. I do not know if this is a compatibility issue with IOS 12 or a bug introduced in the latest version, but it exists in both the iPhone & iPad versions. There doesn’t seem to be a way to contact HP on the issue (no phone or email). The app support link is totally useless since it appears you can only get support for the physical calculator and not the app for which they charge a lot of money for. Extremely frustrated with HP’s poor support with an app that constantly crashes. Beware and keep away until they fix this.
Problems on iPhone 7
Just starting using this app. The touch gestures are having a real problem on the iPhone 7 but work fine on my iPad mini 2. Key click works great on iPhone 7 but are delayed and erratic on iPad mini 2. Will update after more use.
Edit: It seems that the problem with the touch gestures is that this app leaves the standard iPhone title bar on when running which offsets the app graphics down. The app will work fine if you select the "hide title bar" option. This will not remove the iPhone title bar which will appear on top of the app title bar. Not perfect but will work until they fix this bug.
