# Session vs RoundFlow

The clearest difference is in-app purchases: Session at none against RoundFlow's 3. Session also leads on ratings volume (8 vs 1) and iOS requirement (15.1 vs 17.0). RoundFlow's advantage is update cadence (weekly vs every 2 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. RoundFlow sells 3 in-app purchases, starting at $2.99 per month. Session asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Session against 5.0 for RoundFlow. That said, the two scores are not equally well evidenced: Session has 8 ratings behind it against 1, so its average is the more settled of the two.

Session ships an update every 2 months, RoundFlow weekly. The most recent releases landed on September 8, 2026 and September 24, 2026 respectively.
