Verdict
The clearest difference is ratings volume: ALTER EGO at 14K against Parasite Days's 229. Parasite Days's advantage is update cadence (fortnightly vs monthly). On price, rating, review sentiment and ads 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. ALTER EGO sells 7 one-off in-app purchases and Parasite Days sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for ALTER EGO against 5.0 for Parasite Days. That said, the two scores are not equally well evidenced: ALTER EGO has 14K ratings behind it against 229, so its average is the more settled of the two. Written reviews are what separate them: 92% of ALTER EGO's written reviews are positive against 94% of Parasite Days's.
ALTER EGO ships an update monthly, Parasite Days fortnightly. The most recent releases landed on November 9, 2026 and November 7, 2026 respectively.
