Most of the reviews are from poor jobseekers not customers. They're running a job scam that many innocent, young people fell for and wasted their time into. They promise an interview if someone leaves them a review. The owner wants to falsely portray the success of his company but the truth is, the reviews, the app downloads, the social media followers are just part of the job application process.
The owner starts by asking for follow and likes on their social media in order to apply to the job.
Next he would send an email saying someone would contact them to schedule an interview and asks the jobseekers to download the app as a mandatory step. Or the applicants won't be contacted.
He gives instructions like he expects the applicants to create a customer account, thoroughly browse the app and keep their suggestions ready as they'd ask questions in the interview.
After several weeks he sends another email assuring the candidates that someone from the company would indeed get in touch to schedule an interview (which never happens) and encourages them to leave feedback and reviews on the App Store/Play store "in the meantime."
Most innocent, poor jobseekers leave reviews as well hoping for someone to contact them. Then they're ghosted and blocked forever.
They company has already tricked thousands of candidates around the globe with job advertisements and gathered thousands of reviews and a massive following on Instagram and LinkedIn.
Luckily some people were clever enough to notice this and raised their objection.
I have uploaded the email conversations. Have fun reading them!
