Verdict

The call

The clearest difference is rating: Undead Siege at 4.7 against Valor Keep's 2.6. Undead Siege also leads on ratings volume (186 vs 5). Valor Keep's advantage is ads (none vs shown). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Undead Siege holds the better App Store score, 4.7 against 2.6. That said, the two scores are not equally well evidenced: Undead Siege has 186 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 27% of Undead Siege's written reviews are positive against 29% of Valor Keep's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
