Since late 2020, we additionally offer aCalendar and aCalendar+ on Huawei App Gallery.
Differently from Google Play, aCalendar offers upgrades as annually subscription, thus you can choose between a one time purchase (aCalendar+) or a subscription (aCalendar).
You can download aCalendar here https://appgallery.huawei.com/#/app/C102886671
You can download aCalendar+ here https://appgallery.huawei.com/#/app/C101624471
