### 1/5 — This would be great

*2019-12-20*

This would be a great app and be a huge help at work, but it crashes at launch.

Still not working after deleting app, restarting phone, and reinstalling. I’m using an iPhone XS Max running iOS 13.1.2.

Sorry to say, but it’s still not working after the update. The animated title screen does it’s thing but crashes right after.

**Developer response:** Thanks so much for your feedback. It’s an awesome app and as with all apps sometimes due to local settings, phone models and differing iOS versions something goes wrong. We recommend that you confirm with us which phone and software version you’re using then delete the app, restart your phone and r reinstall. This fix has worked well. Thanks for reaching out and giving a glowing review. 

Thanks for the information Dibbla, 
We have just submitted an app update to version 1.3, yours is 1.2. 
Meanwhile, iOS 13.3 is now available, should you like to try updating to the current version, we can confirm it’s working on that, thanks for your patience. This maintenances update should be approved for the App Store in the next week. We’re keen to get it working for you and anyone else but believe it is a reasonably isolated issue.
Thanks again! 

Version 1.3 of designers toolkit is now live. 
Please give that a try Dibbla

### 5/5 — Does a good job

*2019-12-17*

Helpful for my day to day design work.
