Description by Shinichi Nanbu Written by the developer, not by AppBrain. Click to read.
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.

■ Look back on your day (only if you want to)
- At the end of the day, see what you did in the order you did it. Add things you did that weren't planned.
- Send unfinished things to another day, the Inbox, or a smaller next step — or simply let them go.
- Read each day's actual time and notes across a week or a month.

■ 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.
- On iPhone Duo, Flash Log uses the whole screen, closed or open. Open it up and the day list and Inbox sit side by side.

■ 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.
