Back when Google Play (then called the Amazon Market) was starting out apps weren’t available for different parts of the world including India. However Amazon at the time started an app store, which was available in India, for their Android apps to I created versions for it. Amazon at the time did not support maps so those apps, JyotishTools AE and Tropical Skies AE, do not include maps (“AE” stands for Amazon Edition). I attempted making updates in 2019 for these versions but the Amazon AppStore had changed the submission process was a little confusing.
Recently Amazon notified me that if I made a simple change to the apps they could run on Android 14 (Upside Down Cake). I not only did that but brought them up to the same features as the current Google versions though without Maps. Actually last I checked on Google Maps stats they don’t seem to be used much probably because of the extensive atlas which is also included in the new Amazon versions. Hence Amazon versions are discounted a little due to no maps feature.
Also if you’ve drop over the Microsoft Store you’ll also find JyotishToolsAE listed there but it’s a link to the Amazon store. That’s because JyotishToolsAE runs on Windows 11 using the Windows Subsystem for Android.
