The app does have major issues for free users. 1. Changes words from what you type to another different word. 2. Erased sentence. 3. It stops correcting after 3 corrections. You have to start over. 4. When it corrects something, sometimes put that correction in a different spot. Tell I see some improvements in the app. no reason to buy.

It sometimes lag a bit whenever it fixes wrong spellings, but i love having the option to switch keyboards and having a helper available in case I do not want to use the other one! Although I do hope there'll be those long presses for symbols like (") and stuff like in other keyboards. I know it's probably just me being too lazy to go to the number section to click and find it, but it'll feel quite convenient to do so if there are those shortcut symbols like in other keyboards.

This app is great for checking grammatical errors. However, recently the app doesn't scan my work anymore. I don't find it troubling since I realized that I should not rely on this. But what this app made me frustrated is the AI detector feature of it. It's not accurate! even my own journal, sometimes they still detect it as an AI. There was even a time that my classmate accused me of using AI because they used this app. Please, just eradicate that feature. I lost my credibility because of it.
