Verdict

The call

The clearest difference is ads: Geometry at none against Tri's shown. Tri's advantage is rating (4.5 vs 4.0) and ratings volume (17 vs 2). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Tri holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Tri has 17 ratings behind it against 2, so its average is the more settled of the two.
