# EigenGauge vs Survanoid

The clearest difference is review sentiment: Survanoid at 100% against EigenGauge's 55%. Survanoid also leads on rating (4.5 vs 3.7) and update cadence (every 5 days vs every 6 weeks). EigenGauge's advantage is ads (none vs shown) and ratings volume (33 vs 2). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. EigenGauge sells 3 one-off in-app purchases and Survanoid sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Survanoid holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: EigenGauge has 33 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 55% of EigenGauge's written reviews are positive against 100% of Survanoid's.

EigenGauge ships an update every 6 weeks, Survanoid every 5 days. The most recent releases landed on October 17, 2026 and October 5, 2026 respectively.
