# Boostcamp vs Flexius

The clearest difference is ads: Flexius at none against Boostcamp's shown. Flexius also leads on rating (5.0 vs 4.8). Boostcamp's advantage is ratings volume (10K vs 2) and chart position (#145 vs unranked). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Boostcamp sells 20 in-app purchases, starting at $11.99 per month and Flexius sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Flexius holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Boostcamp has 10K ratings behind it against 2, so its average is the more settled of the two.

Boostcamp ships an update fortnightly, Flexius every 3 weeks. The most recent releases landed on October 12, 2026 and October 2, 2026 respectively.
