# ThreadMaster vs RPGViewer

The clearest difference is price: ThreadMaster at Free against RPGViewer's $4.99. ThreadMaster also leads on rating (5.0 vs 3.5) and update cadence (every 3 days vs every 3 weeks). RPGViewer's advantage is in-app purchases (none vs 15) and ads (none vs shown). On device support and iOS requirement there is nothing between them.

ThreadMaster is free to download; RPGViewer costs $4.99 up front. ThreadMaster sells 15 in-app purchases, starting at $3.99 per month. RPGViewer asks for nothing beyond the download.

ThreadMaster holds the better App Store score, 5.0 against 3.5. Both are backed by a comparable volume of ratings — 11 and 45 respectively. Written reviews complicate that: 33% of ThreadMaster's written reviews are positive against 56% of RPGViewer's, so the app with the better star average is not the one people write more warmly about.

ThreadMaster ships an update every 3 days, RPGViewer every 3 weeks. The most recent releases landed on October 22, 2026 and October 18, 2026 respectively.
