# Porter vs WhenFree

The clearest difference is rating: WhenFree at 5.0 against Porter's 4.3. WhenFree also leads on update cadence (daily vs every 2 weeks) and review sentiment (100% vs 71%). Porter's advantage is in-app purchases (none vs 3) and ratings volume (47 vs 2). On price and ads there is nothing between them.

Both are free to download. WhenFree sells 3 in-app purchases, starting at $4.99 per month. Porter asks for nothing beyond the download.

WhenFree holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Porter has 47 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 71% of Porter's written reviews are positive against 100% of WhenFree's.

Porter ships an update every 2 weeks, WhenFree daily. The most recent releases landed on November 7, 2026 and November 13, 2026 respectively.
