What platform are you using? If you're on iOS, you can try apps by The Fool's Dog (my personal favourites, highly recommended). They have four free apps with sample decks that you can try. Or there's Tarot eCards or Tarot & Numerology, both free apps you can check out.
I know Fool's Dog apps are available on Android, but I don't think the other two are. But there's the Uni Tarot app for Android, which people seem to love, and the Galaxy Tone apps, also much loved. I don't have those myself so can't say much about them or their prices, though…
Good luck with your search!
