Stellalyzer
Space Decisions Under Pressure
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Command anomaly missions, balance budget against research, and defend every call.
Take the watch. The signal is real. The answer is not obvious.
Stellalyzer is an offline-first space-operations strategy game about making defensible decisions under uncertainty. Read the evidence, build a plan, commit limited resources, and face the consequences in a mission-control world shaped by three researchers with different strengths.
FIVE OPERATION MODES
- Impact Ops: weigh trajectories, timing, and mitigation tradeoffs.
- Signal Ops: separate meaningful structure from noise.
- Conjunction Ops: protect orbital margins under pressure.
- Cosmic Explorer: manage deep-space observation and communication.
- Sample Return Ops: balance scientific value against mission risk.
A CAMPAIGN THAT REMEMBERS
- Navigate a 10-chapter campaign with branching outcomes.
- Carry research gains, investments, and even failed decisions forward.
- Build six investment paths and recover from soft deadlocks through deliberate replanning.
- Continue beyond the Good End into a high-difficulty post-game story arc.
LEARN BY PLAYING
- Tackle 75 curated anomaly cases grounded in astronomy and space-science concepts.
- Compare counterfactual plans and understand why outcomes changed.
- Build a local research archive, mastery profile, and researcher-specific record.
- Review explainable debriefs with uncertainty ranges, top factors, and after-action analysis.
BUILT FOR REPLAY
- Chase multiple best records, researcher titles, endings, and branch variations.
- Revisit short challenges or attempt full campaign runs.
- Use deterministic simulations so the same choices remain reproducible.
PRIVATE AND OFFLINE-FIRST
- No account and no advertising.
- Progress and learning records stay on your device.
- After a verified purchase, unlocked content remains available offline.
- Backup, export, support, and sharing occur only when you choose them.
Stellalyzer is a fictional learning game. It is not real mission-planning software or operational guidance.
