# WODProof vs FLEX Stronger

The clearest difference is in-app purchases: FLEX Stronger at none against WODProof's 7. FLEX Stronger also leads on ads (none vs shown) and review sentiment (71% vs 39%). WODProof's advantage is rating (4.8 vs 4.4) and ratings volume (845 vs 8). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. WODProof sells 7 in-app purchases, starting at $6.99 per month. FLEX Stronger asks for nothing beyond the download.

WODProof holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: WODProof has 845 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 39% of WODProof's written reviews are positive against 71% of FLEX Stronger's, so the app with the better star average is not the one people write more warmly about.

WODProof ships an update every 3 weeks, FLEX Stronger monthly. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
