It's enjoyable & the artwork is beautifully done. Daily goals are customizable, but there is a variety of preset goals to choose from to get you started. It's calming at the end of your day and refreshing at the beginning. Doesn't leave you frustrated and mentally depleted like most other games. Plus, magic kitties!” “It's clear that the people behind this app care about helping people. I am genuinely floored about how focused the game is on self-care and the player. This is especially apparent in the 'free trial' aspect of this app- none of the self-care elements are behind a paywall, and they have an entire system for people to donate full copies of the game to those in financial need. The game is reassuring and never unhealthily pressures. also the animation is so good. I'd say more but I have no more space.” FINANCIAL NEED? READ BELOW! Want the full version but can’t afford it?

Verdict

The call

The clearest difference is ads: Amaru at none against Alien Evolution's shown. Amaru also leads on ratings volume (1.4K vs 19) and iOS requirement (13.0 vs 15.0). Alien Evolution's advantage is review sentiment (100% vs 86%). On price, rating, update cadence and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Amaru sells 14 one-off in-app purchases and Alien Evolution sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.7 for Amaru against 4.8 for Alien Evolution. That said, the two scores are not equally well evidenced: Amaru has 1.4K ratings behind it against 19, so its average is the more settled of the two. Written reviews are what separate them: 86% of Amaru's written reviews are positive against 100% of Alien Evolution's.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
