# TI vs xFormula

The clearest difference is price: xFormula at Free against TI's $29.99. xFormula also leads on update cadence (every 3 weeks vs every 6 months) and review sentiment (84% vs 65%). TI's advantage is rating (4.6 vs 3.9) and in-app purchases (none vs 4). On ads and device support there is nothing between them.

xFormula is free to download; TI costs $29.99 up front. xFormula sells 4 in-app purchases, starting at $1.99 per month. TI asks for nothing beyond the download.

TI holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: TI has 406 ratings behind it against 55, so its average is the more settled of the two. Written reviews complicate that: 65% of TI's written reviews are positive against 84% of xFormula's, so the app with the better star average is not the one people write more warmly about.

TI ships an update every 6 months, xFormula every 3 weeks. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
