Ring Protein(リングプロテイン)は、 毎日のタンパク質摂取量を「直感的に」「迷わず」管理するためのアプリです。 ■ リング表示で、今日の摂取量が一目でわかる その日に摂取したタンパク質量は、円形のリングで可視化されます。 数値を追わなくても、今どれくらい足りているのか、あとどれくらい必要なのかが感覚的に把握できます。 忙しい日でも、アプリを開いた瞬間に状況が分かる設計です。 ■ 入力は「項目」と「摂取量」だけ Ring Proteinは、余計な情報をできるだけ省いています。 記録に必要なのは 食品名(または食事名)とタンパク質量だけ。 カロリーや栄養素の細かい管理が苦手な方でも、ストレスなく続けられます。 ■ よく食べる食品はワンタップで追加 プロテイン、鶏むね肉、卵など、よく食べる食品はあらかじめ登録可能。 毎日の記録を最短1タップで完了できます。 ■ AIがタンパク質量を推定 食品名を入力するだけで、AIがタンパク質量を自動推定します。 「だいたいこのくらいかな?」という曖昧な食事でも、 記録のハードルを大きく下げることができます。 ※食品データベースに一致した場合は回数消費なしで利用できます。 ■ 目標設定もシンプルに 体重と運動レベルから、1日の目標タンパク質量を推定。 もちろん、自分で数値を調整することも可能です。 分析画面では、日・週単位での摂取状況を確認できます。 ■ 続けることを最優先に考えた設計 Ring Proteinは「完璧な管理」よりも「続けられること」を大切にしています。 ・入力が面倒でやめてしまった ・数字が多くて疲れてしまった そんな経験がある方にこそ使ってほしいアプリです。 こんな方におすすめ タンパク質を意識した生活を始めたい 難しい栄養管理は続かなかった プロテインや筋トレの記録をシンプルに残したい 数字よりも感覚的に把握したい Ring Proteinで、毎日のタンパク質管理をもっと直感的に。
