Verdict

The call

The clearest difference is review sentiment: Endless Frontier at 75% against Idle Ninja Online's 48%. Endless Frontier also leads on iOS requirement (13.0 vs 15.0). Idle Ninja Online's advantage is update cadence (weekly vs every 6 weeks) and rating (4.7 vs 4.5). On price, ratings volume, ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Endless Frontier sells 10 one-off in-app purchases and Idle Ninja Online 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

Idle Ninja Online holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 3.2K and 1.8K respectively. Written reviews complicate that: 75% of Endless Frontier's written reviews are positive against 48% of Idle Ninja Online's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Endless Frontier ships an update every 6 weeks, Idle Ninja Online weekly. Both last shipped on November 11, 2026.
