# Vario One vs Tracerlink

The clearest difference is price: Vario One at Free against Tracerlink's $9.99. Vario One also leads on update cadence (every 5 weeks vs every 3 months) and review sentiment (85% vs 75%). Tracerlink's advantage is rating (3.0 vs 1.0) and in-app purchases (none vs 3). On ratings volume, ads and device support there is nothing between them.

Vario One is free to download; Tracerlink costs $9.99 up front. Vario One sells 3 in-app purchases, starting at $3.99 per 7 days. Tracerlink asks for nothing beyond the download.

Tracerlink holds the better App Store score, 3.0 against 1.0. Both are backed by a comparable volume of ratings — 2 and 1 respectively. Written reviews complicate that: 85% of Vario One's written reviews are positive against 75% of Tracerlink's, so the app with the better star average is not the one people write more warmly about.
