What's New in My Fit Tetra
1.8
October 26, 2026
Apple Watch とひとつながりで、もっと手軽に、止められずに続けられるようにした更新です。 ■ Apple Watch ・文字盤に「クイックスタート」を置けます。最近使った有酸素や屋外ウォーキング・ジョギングを、文字盤からすぐ始められます ・今日のメニューが無い日は、アプリを開くとクイックスタートが一番上に出ます ・休憩のあいだや、iPhone でセットを記録したあとは、「ワークアウトを終了してよいですか?」の確認に数えません ・心拍で休憩を延ばすときの目安を、心拍設定の「休憩明けの心拍の上限」で自分で決められます(空欄なら Z1 の上限) ・筋トレの途中のプランクは、「準備完了」を押してから 3・2・1 で計測を始めます ■ 音と心拍 ・音楽を聴きながらでも、休憩の終わりやプランクの声が鳴ります。声の間だけ音楽を少し下げます ・iPhone がワークアウトを記録している間は、画面を消していても合図が鳴ります ・AirPods で心拍を測っている途中に画面が読み込み直されても、それまでの記録を捨てずに続けます ■ トレーニングの計画 ・カリキュラムで分割法(PPL など)を選べます。1 回だけのプランにも「押す日・引く日・脚の日」 ・カリキュラムに週の総負荷量の目標を立て、週ごとの進み具合を見られます ■ 動画レッスンと記録 ・動画レッスンをプレイリストにまとめ、時間・カテゴリ・追加日で絞り込めます ・履歴と統計の期間を、どの画面も同じ選び方(最近・1か月〜1年・全期間・指定期間)にしました ■ そのほか ・細かな不具合を直し、使い心地を改善しました
