NEW: College Fit — your swimmer's college projection in one tap Wonder where your swimmer might fit in college? College Fit projects their times forward to age 18 across three scenarios — conservative, expected, and aggressive — then ranks NCAA programs by how well they actually match. Every school gets a two-part read: • Conference fit — would they project to score at the conference championship? • Roster fit — would their times earn a spot on this specific team's depth chart? Browse the full ranked best-fits list, or search a specific school. Drill in for event-by-event detail: where they'd place at conference, where they'd rank on the roster, NCAA cuts they'd hit, and how their projection compares to the team's current top swimmers. An AI-generated narrative ties it all together — switch between swimmer-tone and coach-tone for the read that fits you. Filter by school tier (NCAA D1 Power, D1 Mid-Major, D2 — D3 and NAIA coming), conference, target age, and course. Built to grow with the dataset as more programs come online.

Verdict
The clearest difference is review sentiment: SwimCalc++ at 100% against Swimmetry's 25%. SwimCalc++ also leads on rating (5.0 vs 2.9) and in-app purchases (none vs 2). Swimmetry's advantage is ratings volume (234 vs 14) and update cadence (fortnightly vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.
