# Fluenza vs Bug ID

The clearest difference is update cadence: Fluenza at fortnightly against Bug ID's every 5 weeks. Fluenza also leads on rating (4.7 vs 4.5) and ratings volume (35 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Fluenza sells 20 in-app purchases, starting at $3.99 per 7 days and Bug ID sells 4 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Fluenza holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Fluenza has 35 ratings behind it against 4, so its average is the more settled of the two.

Fluenza ships an update fortnightly, Bug ID every 5 weeks. The most recent releases landed on September 13, 2026 and September 19, 2026 respectively.
