### 5/5 — Love

*2026-09-28, version 2.4.1*

How too

### 1/5 — No actual free trial developer non responsive

*2026-09-24, version 2.4.1*

BEWARE Charges you full price without any opportunity to trial the app. IT DOES NOT WORK AS DESCRIBED

### 5/5 — Nice

*2026-09-14, version 2.4.0*

Really helpful

### 1/5 — Waste of time

*2026-07-15, version 2.3.2*

I had this app for less than five minutes before I had to delete it. Way too many ads to even try to use it. Pop-up video ads as soon as you tap the screen. Can’t speak to how well it works as a grammar check tool because I didn’t even have the opportunity to use it before I was bombarded with ads and just decided it’s not even worth it.

### 1/5 — Too Many Ads to Get Anything Done

*2026-07-08, version 2.3.1*

I copy and pasted my work into it, and I cycled through 4 of the 30 second ad videos, 4 8 second ads, and 4 download promos for their keyboard app. I didn’t see any markings on my writing, so I went to see if maybe the settings were off for what I was looking for. I had to watch another 30 second, 8 second, and download promos to open the options. Then, once I selected a different option, I had to watch another of each, and I still didn’t see any markings! I am dyslexic the likelihood of me writing a perfect 4000 words is zero to none. I wasn’t going to watch another cycle of ads for a trial and error on settings. I deleted it after that.

### 1/5 — SCAM!!

*2026-07-01, version 2.3.0*

This App is a scam on people not paying attention. Looked up Grammerly, this had an AD at the top (paid to be at the top) and gets you to subscribe thinking you’re getting Grammerly and then gives you no way to refund. Had to call my bank to get this resolved. Don’t make my mistake!

### 5/5 — Free upgrade

*2026-06-19, version 2.2.7*

Free use we needed

### 5/5 — Great, still  1 in AI checks

*2026-06-14, version 2.2.7*

I use to help red proof stuff while I learn through its amazing corrections.

### 5/5 — It’s good

*2026-05-26, version 2.2.6*

It’s worth it

### 1/5 — A scam and waste of time

*2026-05-25, version 2.2.6*

I spent 20 minutes trying to get into the app and it kept asking me to turn on notifciations and allow full access. This app used to be good but not anymore
