# RepeatOne vs シャドテン

RepeatOne and シャドテン both sit at 4.6 stars, but that hides the real split: 83% of RepeatOne's written reviews are positive against 46% of シャドテン's. シャドテン's advantage is ads (none vs shown) and ratings volume (156 vs 5). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. RepeatOne sells 4 in-app purchases, starting at $4.99 per month and シャドテン sells 1 in-app purchase, starting at $189.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for RepeatOne against 4.7 for シャドテン. That said, the two scores are not equally well evidenced: シャドテン has 156 ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 83% of RepeatOne's written reviews are positive against 46% of シャドテン's.

RepeatOne ships an update fortnightly, シャドテン every 9 days. Both last shipped on October 17, 2026.
