Problem solved

Learners and educators struggle to incorporate proven spaced repetition techniques into their digital tools due to the lack of a simple, universal API. Existing solutions like Anki are powerful but confined to specific apps or require complex setup. Üben solves this by offering a free, cloud-based API that any developer can use to add intelligent flashcard scheduling to their products, thereby making efficient learning accessible across a wide range of platforms and devices.
