Heidelapp gathers the writing and podcasting of the Heidelblog into one app. It is an AppPresser built app for iPhone, iPad and Android, and it holds a 5.0 rating on the App Store and a 4.6 on Google Play.
Who is behind the app
Heidelapp is published by the Heidelberg Reformation Association, a 501(c)(3) nonprofit in Escondido, California, and the parent of the Heidelblog and the Heidelcast. Its purpose is to promote Reformed theology, piety and practice as summarized in the Heidelberg Catechism and related confessions.
The association's founder and president is Dr. R. Scott Clark, professor emeritus of church history and historical theology at Westminster Seminary California. The Heidelcast began in 2009 and has grown into a family of shows, including the Heidelminicast for listener questions.
What Heidelapp does
As the app puts it, you can find all Heidelblog and Heidelcast content in one convenient app. Tabs docked at the bottom of the screen move readers between the blog and the podcast, and episodes play in a built in audio player.

- New Heidelcast episodes, series and the archive, playable in the app
- A built in audio player
