Do you keep a diary? I've tried using various diary apps and paper diaries to see if I could stick with it. But... I couldn't keep it up. Even though I thought, “I should keep a diary! I have to keep one...” I just couldn't make it a habit. That's because... I had to think about what to write. Even if I tried to write at the end of the day, I'd end up thinking, “Huh... what did I even do today?” and using up mental energy just trying to remember. Then, actually writing the diary entry felt like too much trouble. But I still want to keep a record of my days! Well... I have good news for you. This app shows the exact time the moment you press the timestamp button, letting you instantly jot down whatever you want to record. It makes keeping track super easy. It's great for daily journaling, work notes, organizing your thoughts—anything really. You don't even have to press the timestamp button; you can just use it as a memo. And later, when you need to find something, adding tags makes searching a breeze. Plus! It posts to Google Calendar too. So when you wonder, “What did I do that day...?” Or “What was that meeting about last time...?” Just sync everything to Google Calendar, and finding it later is a breeze. ▼ Now supports various communication tools.  ■ If you use LINE, Slack, Teams, Messenger, WhatsApp, etc., you can share necessary notes. ▼ Recommended for:  ■ Those who want to reflect on their daily activities  ■ Those looking to reassess how they use their time  ■ Those seeking a simple note-taking app  ■ Those wanting to start keeping a life log ▼ Main Features 【Timestamp】 Automatically inserts the current time with a single tap.

Flash Log is an app for handling your to-dos simply, so you can move the one in front of you forward. Today's screen shows only today. Write it down, start it, check it off — that's all there is to learn. Finished to-dos tuck themselves away, so the screen always stays quiet. ■ Simple to start - Write down today's to-dos and check them off. That alone is a complete way to use the app. - Completed items hide automatically, so you always see only what's ahead. - Next morning, you choose which of yesterday's leftovers to carry over. Nothing piles up on its own. ■ Focus on doing - Start a to-do and it opens in a full-screen focus view — just you and the one thing. - "Just these today" — pick the few things that really matter today and show only those. - While it's running, it also shows on the Lock Screen, in the Dynamic Island, and on Apple Watch, where you can pause or complete it. - The time you spend is recorded automatically. Your effort leaves a trace. When you finish, you can leave a star rating and a short note as a reflection (optional, of course). ■ Think in time (only if you want to) - Give a to-do a time estimate and the day shows its total — you'll know "today is full" before it happens. - Estimates (gray) and actuals (blue) sit side by side, so you gradually learn what your "30 minutes" really is. - Estimates are always optional. Everything works beautifully without them. ■ Your style, your method - Capture ideas into the Inbox, then drag them onto a day when you decide. (For GTD fans) - Drag to-dos onto a timeline in calendar view. (For timeboxing fans) - Comparing estimates with actuals will feel familiar to TaskChute practitioners. - Use any method fully, partially — or none at all. A plain to-do list is a perfectly good way to use Flash Log. ■ Recurring to-dos that don't pile up - Daily and weekly to-dos appear each day as a dimmed "tentative" preview. - Tap the ones you'll actually do — only those become real. Skipped days never stack up. ■ An everyday tool - Add to-dos by voice. Works with Siri, Shortcuts, and Spotlight search. - Home Screen & Lock Screen widgets, Live Activities, and an Apple Watch app. - Reminders for start and expected end times, search across every day, and your calendar events overlaid on the timeline. - Runs on iPhone, iPad, and Mac, with optional iCloud sync — you decide. ■ Easy to trust - Free. No ads. No account. - Your data stays on your device; sync only uses your own iCloud, only if you turn it on. - Add-by-voice speech recognition runs entirely on your device; your voice never leaves it. - Export your data as plain text anytime. No lock-in. Not for managing your to-dos — for finishing them. Flash Log tries to be a tool that never gets in the way of your pace.
