集中する=深海へ潜る。新感覚の集中タイマー スマホを置いて集中するたびに、あなたは深海へと沈んでいく。 1分の集中 = 1mの潜水。25分のポモドーロで25m。積み重ねた集中が、深海への旅になる。 【深海生物との出会い】 タイマー完了のたびに、深度に応じた生物に遭遇。表層ではクマノミやマンタ、深くなるほどチョウチンアンコウやメンダコなど幻想的な生物が現れる。完全集中(アプリを離れない)だとレア出現率2倍! 【あなただけの水槽】 出会った生物が「マイ水槽」に住み着く。横スクロールで水面から深海まで、ゆらゆら泳ぐ生物たちを眺めよう。深く潜れば潜るほど、水槽が豊かになっていく。 【罰しない設計】 途中でやめても、生物は死なない。完全集中を達成すると、よりレアな生物に出会いやすくなるだけ。プレッシャーなく、自分のペースで続けられる。 【深海図鑑】 30種以上の深海生物を発見しよう。未発見の生物はシルエットで表示。「深度1000m付近に生息」のヒントを頼りに探せ。 【記録・統計】 週次グラフでカテゴリ別の集中時間を可視化。連続日数(ストリーク)で継続のモチベーションを維持。累計深度があなたの努力の証。 【シンプルな操作】 (1) 「潜る」ボタンをタップ (2) カテゴリ(勉強/仕事/読書/その他)と時間を選ぶ (3) スマホを置いて集中するだけ 対応タイマー: ポモドーロ(25分)/ 集中(50分)/ ショート(10分)/ カスタム(1〜180分) BGM: 深度帯ごとに自動切替(波音 > 水中反響 > 低音ドローン) 【プレミアムプラン ¥380/月 / ¥3,200/年】 - 広告完全非表示 - BGM全15種 - 水槽カスタマイズ(背景・光源の色変更) - 図鑑の詳細情報(豆知識・実際の映像リンク) - 高解像度水槽エクスポート(透かしなし) - カテゴリ数無制限 - 集中統計の詳細分析 Forest・gogh・魚が育つアプリの次を探している人に。 深海という比喩が、集中するほど正しくなっていく。 利用規約: https://qtarou11111.github.io/abyssal-web/terms.html プライバシーポリシー: https://qtarou11111.github.io/abyssal-web/privacy.html

FaveLock helps you stop reaching for the apps you can't put down — with a little help from someone you actually want to hear from. HOW IT WORKS Pick the app(s) you keep opening without thinking, and register a photo of your "fave" — anyone whose photo and words motivate you. From then on, whenever you try to open a blocked app, your fave's photo appears with a message instead. Choose Sweet mode for gentle encouragement, or Tough mode if you respond better to some tough love. FaveLock runs entirely on Apple's Screen Time (Family Controls) framework. It never sees which apps you actually chose to block — that information stays private to Apple's system, by design. FREE VS PREMIUM • Free: block 1 app of your choice, forever, at no cost. • Premium: block as many apps as you like, with no limit. Premium is a $1.99/month auto-renewing subscription with a 7-day free trial. Payment is charged to your Apple ID at confirmation of purchase. Your subscription automatically renews unless canceled at least 24 hours before the end of the current period; your account will be charged for renewal within 24 hours prior to the end of the period. Manage or cancel anytime in your App Store account settings. PRIVACY Your fave's photo, your nickname, and your app selection are stored only on your device. FaveLock has no servers and no accounts — nothing about your usage is ever uploaded anywhere. Take back a few minutes at a time. Let your fave help.
