Support an Indie Developer

Alpenglow is built as a passion project by a single developer who loves writing code and watching amazing sunsets. Your support allows me to not only keep Alpenglow running, but to keep making it better.

*Alpenglow never stores your location on a server. So all notifications are scheduled directly on your device.

*In some cases iOS may not wake Alpenglow in the background to allow the app to schedule prediction notifications. Low battery, being in low power more etc can all effect whether iOS allows Alpenglow to fetch the prediction.
