  1. ★☆☆☆☆ Asem Al-Jabari · 19 Oct 2026 · v1.5.2
    I installed the app then I didn't notice theres a subscription first just to use the trial. Then I have uninstall directly the app since I don't know how use it properly. Then after few days I got a notification from my gcash that my balance was deducted because of the subscription when at the first place I didn't get to enjoy the service of the app. Then I keep on sendingrequest refund email for a few days on their support email and I've got NO response. So I decided to make a review here.
