We don't currently offer an app, however the Thinkific Course Player is actually fully mobile responsive so your students will be able to take your courses on the go from any phone, tablet, or computer!
To give some context behind this; Thinkific does not sell courses in a marketplace like some other platforms where they sell courses on behalf of their clients. You can also remove Thinkific branding and use your own custom domain on your Thinkific site, which means building a single app to house all Thinkific sites without it being branded is a challenge.
If you have comments on how a mobile app would help your business and if you would like to add your vote to this feature request, we would love to hear from you. Please send us your feedback!
