Linear Timer+ is an interval timer built for people who work in structured blocks — focus sessions, workout sets, study sprints, cooking timers, or any sequence of named activities. Most timers count down to zero. Linear Timer+ lets you build a full sequence: 25 minutes of FOCUS, 5 minutes of BREAK, then repeat. Each interval has its own label, duration, and color. The timer moves through them automatically, chiming at each transition. Named intervals — call them whatever reflects your actual work. DEEP WORK. STRETCH. COOLDOWN. COLD PLUNGE. Your labels, your rhythm. Live Activity — the timer stays visible on your lock screen and in the Dynamic Island. See your current interval and a live progress bar without touching your phone. Works with screen off — sounds and voice cues fire reliably in the background. Lock your phone and walk away. Logbook — a private on-device record of your focus history. Total time, weekly comparison, a 7-day chart, and time broken down by each of your activity labels. No punishing streaks — just honest information about how you actually spend structured time. Voice cues — optional spoken announcements at each transition: the interval name, time remaining, what's coming up next. Multiple timers — run independent sessions side by side. A workout and a work block at the same time. Scheduled starts — set timers to auto-start at specific times on specific days. Presets — save your favorite configurations and load them in one tap. Pomodoro mode — classic 25/5 technique built in, no setup needed. 100% private — no accounts, no cloud sync, no analytics. All data stays on your device. The Logbook has never seen the internet.
