Fuse hydrogen into a living star. Grow it. Then blow it up — on purpose. SUPERNOVA is a premium-feel idle game about running a cosmic forge. Tap to spark fusion, build 12 generators from Hydrogen Wisp to Singularity Seed, and watch your star physically evolve — protostar, blue giant, red supergiant — until it is ready to collapse. Detonating it is the point: every supernova grants Neutron Cores, permanent power that makes each new universe faster than the last. WHY YOU'LL STAY • Real progress while you're away — production continues offline (extend the cap up to 24 hours with research), and a welcome-back doubler greets your return • A star that actually changes — five visual stages, rendered live, no canned art • Prestige that feels like a finale — a hand-built supernova cinematic, then a stronger start • Numbers that get gloriously big — Million, Septillion, and far beyond • Milestones every few minutes early on, deep multiplier stacking later • Daily missions and streaks that respect your time • 20 research upgrades that shape every run FAIR BY DESIGN • No ads. None. • No energy bars, no forced waits, no progress walls • Fully offline — no account, no sign-in, no internet required • Nothing collected, nothing tracked • Optional purchases exist (time warps, photons, a one-time Supporter Pack), and the entire game is balanced to be completed without spending anything THE LOOP 1. Tap your star and let generators forge Stardust 2. Hit ownership milestones — each one doubles a generator's output 3. Buy research, stack a Photon Surge boost, fill your Piggy Bank 4. Reach collapse readiness... and go SUPERNOVA 5. Keep your Neutron Cores forever. Start again, faster. Built by a solo developer in SwiftUI and SpriteKit. Every pixel is procedural — no asset packs, no stock art. Dark theme, tuned haptics, Reduce Motion respected. Your first universe is waiting. It starts with one atom.

Verdict

The call

The clearest difference is in-app purchases: Idle Mage Academy at none against Supernova's 10. Idle Mage Academy also leads on review sentiment (100% vs 76%) and iOS requirement (15.0 vs 17.0). Supernova's advantage is ads (none vs shown) and rating (4.5 vs 4.0). On price there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Supernova holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Supernova has 82 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 76% of Supernova's written reviews are positive against 100% of Idle Mage Academy's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Supernova ships an update every 2 days, Idle Mage Academy every 2 months. The most recent releases landed on November 10, 2026 and October 31, 2026 respectively.
