Glow Timer
Read full descriptionHide full description
Time flows beautifully, silently. Glow Timer is a visual focus timer for quiet places: libraries, cafes, classrooms, night desks, and any moment where a loud alarm would break the mood. Instead of sound, the screen uses soft light, waves, and edge glow to help you notice when time is up. It keeps the practical clarity of a countdown, but gives each session a calmer visual rhythm. Key Features - Silent Glow Notifications: the screen pulses with light when time is up - Pomodoro-Style Flow: move from focus to break with a clearer pause between phases - Double-Tap Pause: pause or resume without opening menus - Fluid Light & Waves: layered wave animations follow the remaining time - Intuitive Gestures: swipe horizontally to adjust time, swipe vertically to switch presets - Distraction-Free Design: the interface fades away so your desk stays quiet - Gentle Focus Log: see today's focused time without turning productivity into pressure - Emotional Skins: choose colors for study, work, reading, rest, and late-night focus Premium Features - Unlock all premium visual skins with a one-time purchase - No subscriptions - No ads - No tracking Perfect For - Pomodoro focus sessions - Studying in libraries or quiet rooms - Desk work and deep work blocks - Reading and journaling - Meditation or breathing breaks - A silent visual timer you can keep beside you Glow Timer is not here to shout at you. It is a small luminous space for focus, rest, and returning to your own pace.

Verdict
The clearest difference is in-app purchases: CalcHistory at none against Glow Timer's 1. CalcHistory also leads on iOS requirement (15.6 vs 17.0). Glow Timer's advantage is ads (none vs shown) and update cadence (every 6 weeks vs every 15 months). On price and device support there is nothing between them.
