Don’t use it on the iPhone X

This app used to work real well. I had no complaints at all. But now there’s this weird bug or something that makes it nearly impossible for me to save my builds or view old ones that I’ve saved.

What this bug does is whenever I select the “My Build” tab, it doesn’t display anything. As in it doesn’t show any text or even the graphics. But I’m still able to select any previously saved builds if I’m lucky enough to select the right area. So it still functions fine, but if I don’t get lucky and select any of my saved builds or win the lottery when I try saving builds (new or old) I can’t see anything other than the background color.

I’ve tried updating it, deleting/reinstalling the app as well as turning my phone off and back on, but it still won’t work. From what I’ve heard from one review, this happens to iPhone X users. But this didn’t become an issue for me until some time after February (2018). It worked fine until maybe March.

I have just sent them a message about this, but until then I cannot recommend this app for anyone who uses an iPhone X.

Developer Response

Thanks for the review -- the issue only started happening on iOS 11.4.1. It took me awhile to get access to an iOS device with that version, but the problem should now be fixed. Sorry about that!


Needs polishing

Hey developers, thanks for the good work. I use an iPhone 5s and when I click the save button the whole screen goes grey and menus are buttons are still available but I can’t see them. The very same thing happens when I click on my builds.

I found that sometimes if I double clicked the save button, on one out of five tries the screen would actually function properly.

I’d also like to see equipment load on the weapon page too please.

Thanks for the review -- that issue has been fixed in the latest version.


Just needs some minor fixing

This app is great if you want to calculate how much vit you’ll need for a build really quick, plan your stat allocation, and lots of other stuff. But when you try to save or load a build the screen is obscured. The buttons are definitely there, you can see them for a fraction of a second, and you can click the upper left corner to go back. If you could fix this it would probably be perfect.
