# Boostcamp vs Flux

Boostcamp and Flux both sit at 4.9 stars, but that hides the real split: 100% of Flux's written reviews are positive against 60% of Boostcamp's. Flux also leads on ads (none vs shown) and update cadence (weekly vs fortnightly). Boostcamp's advantage is ratings volume (11K vs 1) and chart position (#165 vs unranked). On price, rating, 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 Flux sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Boostcamp against 5.0 for Flux. That said, the two scores are not equally well evidenced: Boostcamp has 11K ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 60% of Boostcamp's written reviews are positive against 100% of Flux's.

Boostcamp ships an update fortnightly, Flux weekly. The most recent releases landed on October 25, 2026 and October 21, 2026 respectively.
