(Strategic Takeaway) {#so-what} Aquarium Sunfish simulation game is a games app that is completely free. It holds a 4.75/5 rating from 12 reviews. > **Bottom Line:** Maintaining the current static state risks total user attrition as modern simulation titles increase their update frequency, so adding requested content would unlock a low-cost engagement loop for the existing user base. **Best for:** Casual mobile users seeking low-stakes, relaxing virtual pet simulation experiences. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit ad-fill rates because the app has been silent for 113 months → ensure revenue continuity ### Outlook: Stable The simulation market is consolidating around titles with frequent content drops, leaving static apps like Aquarium Sunfish simulation game in a niche, low-growth state. The lack of updates since 2017 suggests the developer has no intent to compete for new users, meaning the app will likely remain a legacy utility for its existing base. - ⚪ The nine-year update gap confirms a maintenance-only posture, which limits growth potential but avoids the churn risks associated with aggressive live-ops changes. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.75/5 | | Total Reviews | 12 | | Sentiment | Thrilled (90/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Mixed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Aquarium Sunfish simulation game** (this app) | 4.75/5 | Thrilled | tack | | [Bingo Cash - Win Real Money](https://marlvel.ai/apps/bingo-cash) | 4.7/5 | Excited | Papaya Gaming | | [Royal Match](https://marlvel.ai/apps/royal-match) | 4.7/5 | n/a | Dream Games | | [Archero](https://marlvel.ai/apps/archero) | 4.5/5 | N/A | HABBY | | [Bejeweled Blitz](https://marlvel.ai/apps/bejeweled-blitz) | 3.3/5 | n/a | PopCap | | [Brawl Stars](https://marlvel.ai/apps/brawl-stars) | 4.5/5 | n/a | Supercell | ## Company Profile - **Developer:** tack ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/aquarium-sunfish-simulation-game/id1201642529?uo=4) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*Bingo Cash - Win Real Money*](https://marlvel.ai/apps/bingo-cash) (Papaya Gaming) · 4.7/5 Rating | Positive Sentiment - [*Royal Match*](https://marlvel.ai/apps/royal-match) (Dream Games) · 4.7/5 Rating - [*Archero*](https://marlvel.ai/apps/archero) (HABBY) · 4.5/5 Rating - [*Bejeweled Blitz*](https://marlvel.ai/apps/bejeweled-blitz) (PopCap) · 3.3/5 Rating - [*Brawl Stars*](https://marlvel.ai/apps/brawl-stars) (Supercell) · 4.5/5 Rating - [*Hole.io*](https://marlvel.ai/apps/hole-io) (Voodoo) · 3.9/5 Rating - [*Partymasters - Fun Idle Game*](https://marlvel.ai/apps/partymasters-fun-idle-game) (AI Games FZ) · 4.5/5 Rating | Positive Sentiment - [*Temple Run*](https://marlvel.ai/apps/temple-run) (Imangi Studios, LLC) · 4.3/5 Rating - [*YouRiding - Surf and Bodyboard*](https://marlvel.ai/apps/youriding-surf-and-bodyboard) (BoardScore, Inc.) · 4.2/5 Rating - [*Agar.io*](https://marlvel.ai/apps/agar-io) (Miniclip.com) · 4.3/5 Rating ## Frequently Asked Questions {#faq} ### Is Aquarium Sunfish simulation game still being updated?
