VisibleHour
Read full descriptionHide full description
An always-visible view of time on your phone, your wrist, and your spatial workspace. The day, drained as it passes. Your session, draining as you work. A quiet tap on your wrist when you've been at something too long. For when 30 minutes feels like 5. VisibleHour is a single-purpose external time sense — designed for people whose internal clock isn't always reliable. For time blindness. For hyperfocus. For the moments when "just five more minutes" becomes an hour. The dial isn't a clock face you check. It's a clock face you live alongside, on every surface you already glance at. Three rhythms, on every screen. The day. Your waking hours rendered as a draining amber arc — from the moment you start your day until you wind it down. Tells you how much day is in front of you, not just what time it is right now. The session. A focused block — 15, 25/5 Pomodoro, 30, 60, or 90 minutes. The pie at the center drains as time passes — a visual timer at session scale. Tap it to zoom into a visual timer face with minute marks. Pomodoro mode shows two amber tones — work, then a softer break. The body. A quiet tap on the wrist at the interval you set — 60, 90, or 120 minutes. No banner. No streak. No "you've been at this for two hours" guilt. Just a tap that says: notice the time. Optional desk mode — keep your phone or iPad awake during a session so the dial stays visible while you work. Cross-device sync. Start a session on your Vision Pro while working in spatial. Within a second, the Live Activity appears on your iPhone Lock Screen and the dial fills on your Apple Watch. Stop on the Watch — every screen clears together. Powered by iCloud private database, with no telemetry leaving your device. Calendar-aware. Optionally show your day's events on the dial — a quiet ink line for each meeting, sitting alongside your session. Tap the dial to surface the next event's title. Widgets everywhere. Lock Screen and Home Screen widgets on iPhone. Native complications on Apple Watch in four families. A spatial widget on Apple Vision Pro that coexists with your email, your MacBook display, and whatever else is in your spatial workspace. What it isn't. This is not a habit tracker. Not a productivity hammer. Not a notification machine. There are no streaks, no leaderboards, no "you used the app 12 days in a row" celebrations. There's no analytics, no third-party SDKs, no ads. The whole product is one quiet answer to a quiet question — how much time has passed? Privacy. No tracking. No analytics. No third-party services. The only data that ever leaves your device is the small piece of state that syncs through your private iCloud (active session, day boundaries, awareness interval, appearance preference). Calendar events are read locally on each device — they never sync to the cloud. Made quietly by sthreelabs.

Verdict
The clearest difference is update cadence: Not at every 2 days against VisibleHour's every 3 months. Not also leads on price ($2.99 vs $4.99) and iOS requirement (16.4 vs 18.0). VisibleHour's advantage is device support (4 vs 1). On ads and in-app purchases there is nothing between them.
