I tried a couple of times over the past year, which was not bad, and I felt it could be useful to complement my research. However, after making a recent purchase, I noticed that the database, articles, and indexes have not been updated since January 18. I raised this issue with support, but I have not received a response yet. Therefore, I requested a refund.

PS: Since I’m unable to comment, I’m including this as an edit. I appreciate the straightforward and honest approach of allowing this review to get posted, even with its errors and me giving one star. I’m open to giving HypeIndex another try in the future once the database issues are resolved. While it’s not functioning properly at the moment, I believe the concept holds great promise.
