Ochey

Stop freezing on the finish. Ochey is a focused darts checkout trainer — no match play, just the part that wins legs: closing out the number. WHAT YOU GET • Checkout Finder — type any remaining score (2–170) and instantly see the recommended finish, alternate routes, and what to aim for if you miss. • Full checkout chart — every number, with the classic finishes. Bogey numbers are clearly marked. • Drill mode — the app throws random scores at you; recall the finish from memory, then grade yourself. Your weak numbers come back more often. • Stats — a number-by-number strength heatmap, daily accuracy and streaks, so you can see the finishes you still fumble. • Preferred double — set your favourite double (D20, D16, D8…) and routes are tailored to end on it. MADE FOR PLAYERS Every route is a real, legal checkout that adds up and ends on a double. The numbers are universal, so it works in any language, fully offline, with no account and no ads. Ochey Pro (one-time purchase, no subscription) unlocks unlimited drills, weak-number targeting, full history and preferred-double routes. Step up to the oche ready.

Verdict
The clearest difference is in-app purchases: Dart Theory at none against Ochey's 1. Ochey's advantage is update cadence (every 6 days vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.
