Reach the hidden word before your opponent — using nothing but how CLOSE your guesses are in meaning. A fresh kind of word-guessing duel. Type any word and see its HEAT (0–100): how semantically close it is to the hidden target. The nearer the radar's centre, the hotter. Related words link up into a living "constellation of meaning." Follow the heat, read the connections, and close in. WHAT MAKES IT DIFFERENT - Win by meaning, not letter count or category - A heat radar where every guess sits by its closeness to the answer - Draft 3 self-insight items that change how you read the board MODES - vs AI — four strengths (Easy / Normal / Hard / Expert). - Online — 1-on-1 via Game Center - Nearby — two devices in the same place FEATURES - Deterministic, on-device scoring from 300-dimension meaning vectors. No LLM, no server — instant and consistent - The answer changes every game, so there's nothing to memorize - Japanese / English - Built-in How-to-Play in Settings Note: multiplayer is played between players using the same language setting.

Verdict
The clearest difference is ads: Semantra at none against コトワラ's shown. コトワラ's advantage is iOS requirement (11.0 vs 15.0). On price, update cadence, in-app purchases and device support there is nothing between them.
