Navigate through the void. Survive the barriers. Escape the system. ARC 9 is a fast-paced arcade game where you pilot a ship trapped inside an ancient alien defense system. Massive energy barriers are closing in from all sides — each one a ring of force with only a single narrow gap. Your ship is locked in a fixed orbital path around the station core. The only way out is through. Tap the left or right side of the screen to fire your thrusters and rotate your ship into position. Time your movements carefully — the gaps shift as barriers close in, and the speed only increases the further you go. FOUR THREAT LEVELS Choose your challenge. Easy eases you in with wider gaps and slower barriers. Medium picks up the pace. Hard demands precision. Crazy is relentless — faster walls, tighter gaps, and rapid rotation. Each threat level has its own global leaderboard. EMERGENCY REVIVE Lost all your shields? You get one chance to revive with 3 fresh shields and keep pushing your score higher. ACHIEVEMENTS Unlock 25 achievements across sector milestones, lifetime stats, and skill challenges. Clear 100 sectors without losing a shield to earn INVINCIBLE. Play every threat level to unlock the PROMOTED Achievement! Track your progress in the Rankings tab. GLOBAL LEADERBOARDS Compete against pilots worldwide. Four separate leaderboards — one for each threat level. Submit your best scores through Game Center and see how you stack up. SHIP UPGRADES Remove Ads for uninterrupted gameplay. Grab Extra Shields to start every mission with 5 shields instead of 3. CUSTOMIZE YOUR EXPERIENCE Adjust thruster sensitivity, toggle sound effects, music, and vibrations. Fine-tune your setup in the Systems screen. FEATURES - Simple one-touch controls! Tap left or right to rotate - Progressive difficulty that scales as your score climbs - Synthesized ambient soundtrack that builds suspense - Haptic feedback on every ring pass and shield hit - Extremely smooth gameplay - Responsive design across all iPhone screen sizes No one has ever cleared Sector 100 on Crazy. Prove them wrong, pilot.

Verdict
The clearest difference is ads: Dyno at none against Arc 9's shown. Dyno also leads on ratings volume (1K vs 1) and update cadence (every 3 days vs weekly). On price, rating, in-app purchases and monetization model 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. Dyno sells 10 one-off in-app purchases and Arc 9 sells 2 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 Dyno against 5.0 for Arc 9. That said, the two scores are not equally well evidenced: Dyno has 1K ratings behind it against 1, so its average is the more settled of the two.
Dyno ships an update every 3 days, Arc 9 weekly. The most recent releases landed on November 7, 2026 and October 31, 2026 respectively.
