You might find this useful and it’s free. You can change fonts, size, amend colours, add sound/video and use images on your cards. The cards are presented in random order and you decide how frequently they are reviewed. How it works - Flash cards are presented to you one at a time. Every time one is presented, you choose a score that indicates how well you know it. The score you choose automatically schedules the flash card’s next review.
