Nowbox: Timebox Day Planner

Plenty of apps help you plan a day. Very few make you run it.

A to-do list never tells you when. Nowbox builds your day out of time blocks, then — while you work — shows you one block at a time.

■ Dump it, and the day builds itself Thirty seconds in the morning is the whole ritual. No dragging blocks onto a grid. Set an estimate and a priority; Nowbox fits everything into your working hours and adds the breaks and buffers for you.

■ It learns from your own record (Pro) Nobody focuses on the same schedule. Nowbox learns which half-hours you actually finish things in, and puts your important work there. That learning runs on the device — nothing is uploaded, because there is nowhere to upload it to.

■ While you work, exactly one thing When a block starts, the list disappears. One task, one countdown, nothing else. The Lock Screen widget repeats the same sentence; with Pro, so do the Dynamic Island and the Live Activity.

■ Five seconds at the end Done or not, how focused, how hard. Three taps. With Pro, that record changes tomorrow's plan.

■ An honest day Work that does not fit is not quietly squeezed in. It is listed as "didn't fit today", with the minutes it needs. And on a day you don't keep to the plan, the app doesn't scold you.

■ Completely offline No account. No server. No network requests. No ads, no analytics. What you write stays on your iPhone.

■ Nowbox Pro (one purchase, forever) Not a subscription. Unlimited blocks, the learning auto-plan, full history and the focus heatmap, Live Activity, and every widget. The free app still gives you five blocks a day, the execution screen, reviews, basic stats and a Lock Screen widget — and exporting your own data is always free.
