【課金なし!広告なし】Ghost Weightは、基準日からの差分だけを表示する新しい体重管理アプリです! あなたが入力するのは体重計の数字ですが、アプリが表示するのは「基準日からの差分(例:-0.5kg)」だけ。 「〇〇kg」という重い現実(絶対値)は表示されません。 「昨日より減った!」「先週よりこれだけ変わった!」というポジティブな変化だけに集中できるから、モチベーションが途切れず、自然と習慣が続きます。Face ID / Touch IDによる生体認証ロックを標準装備で、友人や家族に画面を見られても、あなたの本当の体重を知ることは不可能です。数字の呪縛から解放され、心軽やかに健康管理を始めましょう。 【主な機能】 ・差分入力: 実際の体重を見ずに記録完了 ・トレンドグラフ: 「0」を基準にした折れ線グラフで成果を可視化 ・スマートカレンダー: 記録漏れを一目で確認 ・完全ローカル保存: データはあなたの端末だけのもの ・安心バックアップ: 機種変更時もデータを引き継ぎ可能 【こんな方におすすめ】 ・体重の数字を見るのが怖くて、現実逃避してしまう方 ・家族やパートナーに絶対に体重を知られたくない方 ・自分を責めずに、自分のペースで身体を整えたい方

Verdict
The clearest difference is in-app purchases: Ghost Weight at none against Fitona's 1. Ghost Weight also leads on ads (none vs shown) and update cadence (daily vs every 2 months). On price and device support there is nothing between them.
