andOTP was recently removed from the Google Play Store for violating their payment terms.
This is most likely due to the fact that we offer in-app donation links that DO NOT use Googles In-App billing, which is against their terms.

.

andOTP is finally back on the Play Store. This was achieved by using a specific build flavor for the Play Store which does not show any donation links.
