We also offer aCalendar and aCalendar+ on Amazon App Store.
Due to policy restirictions by Amazon and limitations of the Kindle Fire OS, there may be slight variations in the version published on Amazon Apps store.
We push updates to Amazon App Store and Google Play, but due to differences in the update/rollout process in the two stores, the updates are not always simultaneously.
The 2.0 update in Amazon App Store is available now!
