However, I decided to scroll all the way down to some of the ones I published a while ago and they seem to have disappeared and been deleted from my profile. I would like them to return and I’m not sure why they are gone. ### 3/5 — 글쎄 *2019-07-12, version 3.4.0* 독서기록 남기는 방식은 좋은데 앱이 자주 멈추고 느리게 돌아가는 등 많이 불안정하네요. ### 1/5 — Error Error Error *2019-02-11, version 3.4.0* From the moment of installation all I received was errors. Not worth the frustration. Garbage! Don’t waste your time! ### 4/5 — Love it but... *2018-12-01, version 3.1.6* It would be so great if we were able to use this app on the web as well 🙏 **Developer response:** You can in fact use this app in the web. Please visit https://highlightbook.com it's still on beta but usable. ### 1/5 — Why is log in required? *2018-10-27, version 3.0.0* I’m giving this one star because it’s not clear to me why one needs to log in via FB to simply annotate some text. Perhaps I don’t understand how the app is to be used. **Developer response:** As noted, this is a book club based on highlight, so we need your identity. ### 5/5 — Great!!! *2018-03-22, version 1.4.5* Great! **Developer response:** Thanks! ### 5/5 — This app is the best *2018-02-18, version 1.4.2* Enhances your reading experience so much!! I love the tagging feature because i can look back at different excerpts under themes I created. I also love that this like a reading SNS and I can explore other people’s insights. Wish this app becomes bigger and more people get on it! **Developer response:** Thanks. Please let us know if you need anything. :) ### 3/5 — Needs something *2018-01-20, version 1.3.0* The highlighters are beautiful. The colors are A+, they’re delicate and and they don’t lighten the text underneath them, which is great. However, it’s too restrictive for my uses. I want to be able to upload a text screenshot, highlight it, then save it back into my camera roll to do with as I please. Would also be helpful to be able to see the photo you’re highlighting as full screen, or at least somewhat bigger. Zooming in on the areas you aim to highlight would be helpful as well. **Developer response:** Hi! You can download the image from the app anytime. Click the photo and you will be able to zoom it and see sharing (to include to camera roll) options. ### 4/5 — Great App, Freezes with Facebook Login *2018-01-19, version 1.3.0* I haven’t even been able to try this app because once I log in with Facebook it says Connecting but never goes any further and this has been happening since yesterday (Jan 18th) and I tried again today about one hour after the latest update; however I was able to login using my email. **Developer response:** Hi! Sorry for inconvenience. The server was freeze for a moment. It all works normal now. Thanks! ### 5/5 — Love it *2017-12-05, version 1.1.9* Love how I can organize quotes!! **Developer response:** Hope it enhance your reading experience! :) ## Frequently asked questions about Highlight ### What is Highlight's main purpose?
