前回よりも強くなる。 ジムでこの意識を持てないと、今日のトレーニングはなんとなくで終わってしまいます。 Deltaは、同じ種目の「前回」と「今日」を比べることをコンセプトにした筋トレ記録アプリです。 できること: ・前回の重量と回数を自動で引き継ぎ。入力は数字を少し直すだけ ・次に挙げる重量を提案 ・毎回の種目が決まっている人向けのテンプレート機能 ・推定1RM(今の実力で1回挙げられる重さの目安)の推移をグラフで表示 ・週ごとの総ボリュームと、部位ごとの偏りをチェック ・自己ベスト更新をトロフィーで表示 ・RPE / RIR は、使う人だけ記録可能 ジムで使いやすいように、数字は大きく、ボタンは片手で押しやすい位置に配置。 画面はシンプルで、余計な飾りはありません。 記録は端末内に保存されます。アカウント登録は不要です。 広告は買い切り(¥400)で非表示にできます。サブスクではありません。 日本語と英語に対応しています。 昨日の自分との差分を、今日の力に。 Deltaは、前回より強くなるための記録アプリです。

Verdict
The clearest difference is in-app purchases: GoGym (e6bba3) at none against Delta's 1. GoGym (e6bba3) also leads on ads (none vs shown) and update cadence (every 5 days vs every 11 days). On price, device support and iOS requirement there is nothing between them.
