With iOS 11, Terminology comes into it’s own. On an iPad Pro I have it side by side with my writing app and look up words as I go, or have it as a third window off screen that I slide into view when needed. Very nice. This app is the beginning of something great. It’s annoying, though, that it takes two presses to start a new search from a previous search. That baffles me, everything else is so well thought out. It’s worrying that the developer misses that. Otherwise, awesome. I’m looking forward to digging into the extensible options to see what else it can do for me.
Unfair reviews
ozhero
Just reading a couple of the previous reviews where they are accusing the developer of being dodgy etc because they are too stingy to pay less than ½ a single cup of coffee to unlock the new (and much improved) version of the app.This is the developer who created Drafts one of my favourite apps on iOS and now on MacOS. Dodgy couldn’t be further from the truth.I’ve been using Terminology since Day 1 and love it.Next time I’m buying a cup of coffee I will think of what a great value this app is 😏
Clunky
Paradimn
Latest update has made this app slow and difficult to use. The search function is hidden away and difficult to return to. Often the keyboard does not appear when tapping the search window.It used to be slick and easy to use, but no longer.
In-app ad shakedown
Dhebxhxush
App was a paid ad-free app, developer updated to include in-app advertising that is distasteful and intrusive. Requires in-app purchase to remove advertising. Effecting a shakedown of existing purchasers of their old app in order to force a paid upgrade to a new version is a 🍆 move (Tried to use Terminology to find an appropriately descriptive word here but couldn't bear using it after fourth full screen ad). I'm looking for an alternative paid-app where the developer treats customers better.
Update offline dictionary to 2025+ Open WordNet edition, more resources in library.
