About
From the App Store SourceExact Values is a focused drill-trainer for the trigonometric values every maths student needs to know cold: sin, cos, and tan at 0°, 30°, 45°, 60°, 90° (and their radian equivalents). WHY THIS APP • 15 values × repetition = mastery. That's the whole secret. • Daily reminder nudges you to a 2-minute drill — that's all it takes. • Offline. No login. No ads. No tracking. • One-time purchase, $4.99. Yours forever. FEATURES • 10-question quiz rounds drawn from the 15 special-angle values • Optional 5-second per-question timer for exam-pace practice • Toggle radians on or off (π/6, π/4, π/3, π/2) • Accepts both 1/√2 and √2/2 — equivalents are equivalents • Per-question accuracy charts so you see what to drill next • Streak tracking — keep the chain alive • Daily reminder notification at the time you choose • Built for iPhone and iPad PRIVACY Your stats live on your device. We collect nothing. No accounts, no servers, no analytics. Open the app, drill the values, close the app. Companion to https://www.exact-values.com/
