### 5/5 — Wow! I didn’t expect this would work but it’s amazing

*2020-04-30*

I figured this was going to be a fraud or some scam or if not that then I assumed it wouldn’t work. I noticed it didn’t have any reviews so didn’t download it. A couple days later I decided to give it a try and it is great. This is the only app I’m aware of that can diagram English sentences instantly. I haven’t found anything comparable online either. There is the Kellogg-Reed thing that supposedly works but seems to be just an old piece of technology that might have worked but now is on an unsafe website. Anyway, my hat is off to the developers of this app. It is amazing in that it does exactly what it claims and is also free! I don’t think I’ve rated any app before except maybe audible. Anyway, like I said: free. Amazing. Does what it claims. Thanks for creating this I’ve been looking for something like this for a long time. 👍😎🔥

**Developer response:** Hello. I am currently running into a background running bug in ios 13.5.1 that causes the battery to run out quickly. PRO version has the same problem. There is a conflict between the built-in ad and the new ios version. Due to an iOS bug, please swipe the app in multitasking to close the app manually after using the app. And as the new ios update, a new update of the PRO version is scheduled. Currently, this free version has no future updates and will be discontinued. The update proceeds mainly on the PRO version. Thank you.
