App crashes before opening

The developer advises many of us to report the crash in the app, but for me, the app does not open. It starts, then crashes. There’s no way for me to enter the information requested because the app does not open. I’m using the latest IOS

Just for reference

It works fine as a Latin dictionary for reference. It shows the word’s frequency rank. It would be great to list the most frequent words in Latin, this would be especially helpful for new learners.

Fantastic, until it started crashing

I use Logeion constantly on the web. Partly because about a year ago the app started crashing on both my iPad and iPhone. I love it immensely, but I really wish that it would work in ios again. Yes, my software is up to date. My iPad Pro is older, but it also fails on my iPhone 14 Pro. But I love it enough to tell you to give it a try and be delighted if it works on your device. If it doesn’t, you should still use the web version. As a Latin instructor I love the ability to show my students examples of how a word actually works in context using the usage examples. Rather than drag the giant OLD or Lewis (and Short) into the classroom I can just throw this on the board and model how to use a dictionary (and how wrong their textbook is at times, “Me, see, I told you this word is almost never found in existing texts, see that, ‘fewer than 50’.). I also love the concordance to commonly used Latin textbooks such as Learn to Read Latin or, shudder, Wheelock. I love this app so much that I have not removed it from my devices in the faint hopes it will be updated and start working again. Please let this be so. Are offerings required? To Mercury? Minerva? Thoth? Hermes Trismegistos? Do Tell!

Can we get an update?

I love this app and use it almost every day. But it’s over four years old and not optimized for any of the newer phones from the last three years. It still runs in letterboxed format on any phone from the iPhone 10 or later. Can we get an update?

OPTIMISE IT for iPhone 6, please

A very good and useful app, well realised. It deserves 5 stars! However, it must be optimised for the iPhone6 screen...

Great!

This is a great app. One suggestion, lose the hamburger at upper left and replace it with a search icon of some kind. That's what it does. It's not a menu, though even there the hamburger is problematic.

Great but...

Thank you for making this app. It's amazing, especially since it is free. However, it hasn't been updated for almost two years. So there are some glitches on my iPhone 6+. It will be even more amazing if you can fix those bugs (for example, if I start the app when the iPhone is held horizontally, the keyboard blocks half of the screen and I have to restart the app).

Thank you for keeping updated!

Thank you for the recent update making Logeion usable again! It’s the best platform for accessing Classics dictionaries on iOS. I really enjoy offline access for reading on the go, the dual functionality for Latin and Greek, and the choice of dictionaries.

Makes no sense

Layout is lazily made, everything is abbreviated and instead of the actual app being any use they lead you to a website. Extremely limited for simple words and almost impossible to use

Life-changing

As an alphabetically challenged Latin and Greek nerd, I use this app every day. I can’t believe it’s free and has no ads! So much faster than looking things up in a paper dictionary, and I absolutely love all the examples from different texts. The only problem is that it’s very easy to click by accident on the wrong word from the suggestions list, and end up in an entry about a bizarre word that shows up once in extant literature when you just wanted to see if amo has a long or short a.
