Himotoku: Diary & Assistant

Ask your past self. "When did I last talk with Tanaka?" "What did I spend last month on?" — every answer comes with its source page. If your diary doesn't say, Himotoku says so. ■ Talk for 90 seconds Say what happened today. It is transcribed on this iPhone and organized into a readable diary page. No typing, no willpower needed. On days you would rather write, type it. Keep the text as written, or have it organized the same way, with to-dos and plans picked out. When to-dos and plans are found, add them to Reminders and Calendar with one tap. Nothing is added unless you tap. ■ Ask your past Ask your pages in plain words. Answers cite the day they came from and never invent what isn't written. "When did I decide that?" "What was I doing this time last year?" — your diary becomes something you can use later. ■ Bring in paper diaries Photograph years of paper diaries. Whatever can be read becomes searchable in your timeline. The original photos stay with the page. ■ Your diary stays on this iPhone • Your diary is never stored on the developer's servers (there is no database to store it in) • It is never used to train AI • Your voice never leaves the device; speech is transcribed on this iPhone • Only when organizing or answering a question, the text for that one step is sent to Microsoft's Azure AI service (Japan region) for AI processing. It may be retained for up to 30 days for abuse monitoring • Export everything as Markdown and audio at any time ■ Free and paid Free: your first 30 entries, spoken or typed, organized by AI. Your first 3 questions to your past. Plus (monthly, 7-day free trial): unlimited recording and organizing, ask your past, and search by meaning. Renews automatically after the free trial; cancel during the trial and you pay nothing. After those 30, your existing pages stay readable and searchable, and you can still export everything as Markdown and audio, for free. ■ A quiet app No nagging notifications (the only one, if you opt in, is a monthly export reminder). No countdowns, no full-screen ads. Requires iPhone with iOS 17 or later. Japanese and English.
