Verdict
The clearest difference is ratings volume: Comet at 7.8K against Eligian's 1. Comet also leads on iOS requirement (18.0 vs 26.5). Eligian's advantage is rating (5.0 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Comet sells 3 in-app purchases, starting at $20.00 per month and Eligian sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Eligian holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Comet has 7.8K ratings behind it against 1, so its average is the more settled of the two.
Comet ships an update every 8 days, Eligian every 2 weeks. The most recent releases landed on November 1, 2026 and October 20, 2026 respectively.
