# Jam Lab vs StrumForge

The clearest difference is in-app purchases: Jam Lab at none against StrumForge's 4. StrumForge's advantage is ratings volume (58 vs 1) and update cadence (every 2 days vs every 6 days). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. StrumForge sells 4 in-app purchases, starting at $2.99 per 7 days. Jam Lab asks for nothing beyond the download.

Jam Lab holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: StrumForge has 58 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Jam Lab ships an update every 6 days, StrumForge every 2 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
