将棋Arena は、ルールに妥協しない本格派の将棋アプリです。ひとりで指すのも、世界中の相手と対戦するのも、詰将棋を解くのも、これ一つで完結します。 ■ 正確なルール 成り、持ち駒、二歩、行き所のない駒、打ち歩詰め、詰み、千日手、連続王手の千日手まで実装しています。反則手はそもそも指せないので、ルールを覚えながら安心して指せます。 ■ CPU 対戦 初級・中級・上級の三段階。初級はこれから覚える方の練習相手に、上級は本気の一局に。先手・後手のどちらも選べます。 ■ オンライン対戦 ランダムマッチですぐに対戦相手が見つかります。対局中に接続が切れても、開き直せば同じ局面から再開できます。 ■ フレンド対戦 8桁のフレンドコードを交換して、友だちと直接対局できます。 ■ 観戦 いま進行中の対局を、リアルタイムで盤ごと眺められます。 ■ 詰将棋 140問 1手詰90問、3手詰50問。やさしい問題から順に並んでいます。ヒントと解答つきで、解けた問題は記録されます。 ■ 対局の解析 指し終えた将棋をエンジンが読み直し、評価値の推移、最善手、疑問手や悪手を指摘します。どこで形勢が動いたのかが一目で分かります。 ■ 棋譜 KIF 形式に沿った表記で棋譜が残ります。局面と指し手は SFEN/USI で扱っているので、他の将棋ソフトとも地続きです。 ■ 見た目を自分好みに 基調色と盤の色を、6つのプリセットまたはカラーピッカーで自由に変えられます。 ■ プロフィール 表示名とアイコンを設定して、対 CPU の戦績を記録できます。Apple ID と連携すれば、機種を変えてもそのまま引き継げます。 将棋は日本で1000年以上受け継がれてきたゲームです。その面白さを、日本の方にも、これから将棋に触れる世界中の方にも届けたい。そう考えて作っています。

Verdict
The clearest difference is in-app purchases: 将棋Arena at none against Shogi Lab's 1. Shogi Lab's advantage is update cadence (every 3 days vs weekly) and iOS requirement (17.6 vs 26.5). On price, ads and device support there is nothing between them.
