Track your anime. Never miss an episode. Sparky remembers where you got to in every show you follow and tells you when the next episode is out. WHAT IT DOES โข Continue watching - everything you follow on one screen, next episode on top. One tap marks it watched and the count moves on by itself. โข Release calendar - every episode of every show you follow, day by day, with its airing time. โข Watch order - seasons, movies, OVAs and specials on one page, in the order you're meant to watch them. Filler episodes are flagged, so you can skip them or watch them knowing what they are. โข Stats and medals - episodes, hours, days, genres. Medals unlock behind your back and you can pin your three best ones on your profile. โข Tier lists that build themselves - rate a series from 1 to 10 and it drops into its row, S down to F. No dragging posters around for twenty minutes. โข Lists that are yours - the rewatch pile, the ones you dropped at episode three, whatever you need. THE SOCIAL PART, WITHOUT THE FEED Follow the people you actually talk to about anime and see where they got to in a series. Drop a comment or a GIF under the episode you just finished; anything flagged as a spoiler stays covered until you tap it. Your account can stay private, and you can block whoever you want.

Verdict
The clearest difference is update cadence: Sparky at every 3 days against Ueno's every 3 weeks. Ueno's advantage is iOS requirement (18.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
