# Legacy TriDot vs T

The clearest difference is in-app purchases: T at none against Legacy TriDot's 5. T also leads on rating (5.0 vs 4.7). Legacy TriDot's advantage is ads (none vs shown) and ratings volume (263 vs 2). On price, review sentiment and update cadence there is nothing between them.

Both are free to download. Legacy TriDot sells 5 in-app purchases, starting at $14.99 per month. T asks for nothing beyond the download.

T holds the better App Store score, 5.0 against 4.7.
