# ThreadMaster vs Spark

The clearest difference is review sentiment: Spark at 81% against ThreadMaster's 33%. Spark also leads on ads (none vs shown) and ratings volume (191 vs 11). ThreadMaster's advantage is price (Free vs $6.99) and update cadence (every 4 days vs monthly). On in-app purchases, monetization model, device support and iOS requirement there is nothing between them.

ThreadMaster is free to download; Spark costs $6.99 up front. ThreadMaster sells 14 in-app purchases, starting at $0.99 per month and Spark sells 5 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

ThreadMaster holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Spark has 191 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 33% of ThreadMaster's written reviews are positive against 81% of Spark's, so the app with the better star average is not the one people write more warmly about.

ThreadMaster ships an update every 4 days, Spark monthly. The most recent releases landed on September 28, 2026 and September 30, 2026 respectively.
