# Spark vs RPGViewer

The clearest difference is in-app purchases: RPGViewer at none against Spark's 5. RPGViewer also leads on price ($4.99 vs $6.99). Spark's advantage is rating (4.8 vs 4.3) and review sentiment (81% vs 56%). On update cadence, ads, monetization model and device support there is nothing between them.

Spark costs $6.99 and RPGViewer $4.99 up front. Spark sells 5 in-app purchases, starting at $5.99 per month. RPGViewer asks for nothing beyond the download.

Spark holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Spark has 223 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 81% of Spark's written reviews are positive against 56% of RPGViewer's.

Spark ships an update every 4 weeks, RPGViewer fortnightly. Both last shipped on November 4, 2026.
