# Symphonium vs FlashHack

The clearest difference is rating: FlashHack at 5.0 against Symphonium's 3.4. FlashHack also leads on ads (none vs shown). Symphonium's advantage is update cadence (every 8 days vs every 3 weeks) and ratings volume (5 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Symphonium sells 2 in-app purchases, starting at $1.99 per month and FlashHack sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

FlashHack holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: Symphonium has 5 ratings behind it against 1, so its average is the more settled of the two.

Symphonium ships an update every 8 days, FlashHack every 3 weeks. The most recent releases landed on October 6, 2026 and October 4, 2026 respectively.
