Cortex vs Gear

Cortex is a focus timer for deep work and study — Pomodoro 25/5, Long Focus 50/10, Short Sprint 15/3, an open-ended Flow mode, 19 ambient tracks and a sleep timer. Built for people who think for a living: students revising for exams, developers and designers in deep work, writers, and anyone with ADHD who needs sound and structure to get started. Four timer modes, three focus sounds, session history, streaks, heatmaps and Apple Health are free. Premium adds the AI Adaptive mode, 16 more sounds, the sleep timer, custom presets, Health Insights and the weekly report. No ads, no account, no sign-up. You track your workouts. Your sleep. Your macros. But not your focus. Cortex closes that gap: it measures your sessions, sizes the next one around your recovery, and shows you the hours your attention actually peaks. STRUCTURED FOCUS MODES Pomodoro (25/5) — Classic deep work intervals Long Focus (50/10) — Extended sessions for complex tasks Short Sprint (15/3) — A low-friction way to start on a bad day Flow Mode (no limit) — Open-ended, stop when you are done AI Adaptive (Premium) — Session length set for you, not guessed Custom Timers (Premium) — Your own work rhythm, up to 10 presets AI ADAPTIVE TIMER (PREMIUM) Instead of asking how long you can concentrate, Cortex works it out. With Apple Health connected it reads your heart rate variability and last night's sleep; without Health it falls back to a time-of-day model. Keep finishing your sessions and it extends them. 19 AMBIENT TRACKS Focus: lo-fi beats, acoustic, downtempo, neo-classical, space ambient, cinematic, chillwave, jazz hop, deep pulse, ethereal piano. Sleep: ethereal pads, deep drone, analog wash, submarine, harp lullaby, binaural, distant choir, zen garden, zero gravity. Three focus tracks ship inside the app and are free. The other 16 come with Premium and download on demand, Wi-Fi recommended. Audio keeps playing with the screen locked. SLEEP TIMER (PREMIUM) Six durations from 15 minutes to 2 hours. Sound fades out gradually and stops — no alarm at the end. A morning check-in records how you slept and whether you woke up rested; with Apple Health connected, the sleep screen also shows last night's stages and a sleep score. DATA, NOT FEELINGS Focus Score — weekly performance metric Peak Hours — the hours your attention actually peaks Heatmaps — focus patterns across the month Weekly Report — personalized recommendations computed on device from your own sessions (Premium; the first week is free) Streaks & Achievements — gamified progress that compounds daily CSV export of every session (Premium) APPLE HEALTH, READ ONLY Only when you tap Connect, and only three data types: heart rate variability, resting heart rate and sleep analysis. Cortex never writes anything to Apple Health. Those readings, and the recovery and sleep scores computed from them, stay on your device and are not sent to analytics. The app works fully without Health. 10 languages · Neo-brutalist design · No ads · No data selling · Usage analytics can be switched off in Settings Built for people who use Notion, Linear, and Arc — not pastel wellness apps Your brain is a machine. We help you run it at peak RPM. --- SUBSCRIPTION INFORMATION Cortex Premium is available as Monthly, Annual, or Lifetime purchase. - Payment is charged to your Apple ID at purchase confirmation - Subscriptions automatically renew unless canceled 24+ hours before period end - Manage or cancel anytime in Account Settings after purchase - Privacy Policy: https://cortex-focus.com/privacy/ - Terms of Use: https://cortex-focus.com/terms/

■ 集中力の残量を、燃料計のように。 1 日に集中できる時間の上限を決めると、 「今日はあとどれくらい集中できるか」が、画面の上にずっと見えます。 ■ 3 つのモード Deep： 深い集中。コードを書く、設計を考える、文章を構成するなど。 Drive： 軽い作業。メール・会議・ルーチンワークなど。 Rest ： 休息。コーヒーを淹れる、散歩する、ぼんやりするなど。 作業の変わり目に3つのモードを切り替えるだけ。あとは Gear が、そのモードに費やした時間を記録します。 ■ Apple Watch から、すぐ切り替え スマホを伏せて作業に入るとき、手首からワンタップでモードを切り替えられます。 記録のためにスマホを起こす必要はありません。 ■ ちゃんと休めているかも、見える 休憩中もスマホを眺めていた日と、画面から離れていた日。同じ「30分の休憩」でも、戻ったときの頭の軽さは違うかもしれません。 Gear では休憩を Analog(画面オフ) と Digital(画面を見る) で分けて記録できます。 「ちゃんと脳を休められた休憩は、週のうちどれくらいだったか」も、ひと目に。 デジタルデトックスの記録としても使えます。 ■ こんな人に ・午前は集中できるけれど、午後は集中が浅くなる感覚がある ・1日に深く考えられる時間が減ってきたと感じている ・タスク管理ではなく、認知リソースの記録が欲しい ・休憩中もスマホを見てしまい、休めていない気がする ・作業中にスマホから離れて集中したい。 ■ できること ・1日の集中時間の上限を決めて、残量をホーム画面で常時表示 ・3モード(Deep/Drive/Rest)の時間を、タイマーで自動記録 ・休憩を Analog/Digital で分けて記録、週で振り返り ・Apple Watch からの切替・停止・休憩タグ付け ・Live Activity / Dynamic Island で、アプリを開かず状況確認 ・iOS 集中モード ON で Gear のモードも自動切替 ・モードごとに残せる一言メモ、8種のカラーテーマ ■ データの取り扱い 記録した集中・休息のログ、メモは、あなたの iPhone の中だけに保存されます。アカウント登録なし、広告なし。 ---------- 利用規約（EULA）：https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ プライバシーポリシー：https://www.notion.so/34693295f40f80ce8688eb95268c87f5
