Verdict

The call

The clearest difference is rating: Tower Defense at 4.4 against Space War TD's 3.8. Tower Defense also leads on ratings volume (2.5K vs 12). Space War TD's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 7 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Space War TD sells 9 one-off in-app purchases and Tower Defense sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Tower Defense holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: Tower Defense has 2.5K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 81% of Space War TD's written reviews are positive against 71% of Tower Defense's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Space War TD ships an update every 3 weeks, Tower Defense every 7 months. The most recent releases landed on November 6, 2026 and November 11, 2026 respectively.
