集中した時間の長さが、そのまま潜水艦の到達深度になります。 25分の集中で水深450m。90分なら1500m。深く潜るほど暗くなり、そこにしかいない深海生物と出会えます。集中を中断してアプリを離れると緊急浮上となり、その航海で捕らえた生物はすべて失われます。 実在の深海生物101種 マリアナ海溝の底に暮らすカイコウオオソコエビ、体長比で全魚類最大の牙を持つオニキンメ、鯨の骨だけを食べるホネクイハナムシ。すべて実在の生物で、それぞれに解説がついています。捕らえた生物は剥製として図鑑に収めるか、水槽で泳がせるか、港で売るかを選べます。 潜れる深さは、二つの要素で決まります コインで買える潜水艦の耐圧殻と、航海の回数だけで伸びる乗組員の胆力です。お金では買えない成長があります。海溝の最深部、チャレンジャー海淵の11,034mに到達するには、たくさんの航海が必要です。 集中のための音 低い環境音が途切れずに流れ、その上に泡の音がときどき乗ります。数分に一度、遠くで鯨が鳴きます。長時間かけっぱなしにする前提で設計してあり、耳が疲れる純音を含みません。周囲の物音を覆い隠す働きが期待できます。モノラルビートを含みますが、脳波への作用を主張するものではありません。 設定でオンオフが可能です。 ### そのほか - 5分から24時間まで、5分単位で設定できます - 電話や通知で一瞬離れても、90秒以内に戻れば航海は続きます - 潜った深さの累計を、東京スカイツリー何個分といった単位で表示します - 通信を行いません。データは端末内にのみ保存されます - 広告はありません --- 集中の深さを、水深で測る。

EkiTime is a pomodoro-style focus timer that turns your focus sessions into Shinkansen journeys across Japan. Pick your departure station, choose a destination that matches how long you want to focus, punch your ticket through the gate, and depart. While the train runs, you focus. When you arrive, a station stamp is pressed into your notebook — your focus history becomes a travel log of stations visited, distance covered, and time focused. FEATURES • Buy a ticket and pass the gate — a small ritual to start focusing • Your train actually runs along Japan's real Shinkansen network • Authentic in-train departure boards (4 selectable styles) • Live Activity: check remaining time on the Lock Screen and Dynamic Island • Home Screen widget — departure board while riding, your ticket while idle • Door Lock: temporarily restrict apps you choose during a ride (Screen Time) • Station stamp notebook with ekiben (station bento) collection • Focus reports styled after real Japanese railway tickets and timetables PRIVACY • No account required • All records stay on your device — nothing is sent to servers • Location is used only on-device to suggest your nearest station So—how far will you ride today?
