# Truth Table Builder vs Symbols

The clearest difference is price: Symbols at Free against Truth Table Builder's $1.99. Symbols also leads on review sentiment (100% vs 60%) and update cadence (every 6 weeks vs every 6 months). Truth Table Builder's advantage is in-app purchases (none vs 6) and rating (4.7 vs 4.5). On ads, device support and iOS requirement there is nothing between them.

Symbols is free to download; Truth Table Builder costs $1.99 up front. Symbols sells 6 in-app purchases, starting at $3.99 per month. Truth Table Builder asks for nothing beyond the download.

Truth Table Builder holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Truth Table Builder has 58 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 60% of Truth Table Builder's written reviews are positive against 100% of Symbols's, so the app with the better star average is not the one people write more warmly about.

Truth Table Builder ships an update every 6 months, Symbols every 6 weeks. The most recent releases landed on September 9, 2026 and June 1, 2026 respectively.
