# Supernova vs Idle Forge

The clearest difference is in-app purchases: Idle Forge at none against Supernova's 10. Idle Forge also leads on iOS requirement (15.0 vs 17.0). Supernova's advantage is ads (none vs shown) and update cadence (every 2 days vs every 6 days). On price there is nothing between them.

Both are free to download. Supernova sells 10 one-off in-app purchases. Idle Forge asks for nothing beyond the download.

Supernova ships an update every 2 days, Idle Forge every 6 days. The most recent releases landed on November 3, 2026 and October 29, 2026 respectively.
