-- Is this app for me? -- Students, software developers, writers, artists — anyone with a todo list. Cucumber Timer is for those who want to achieve their daily goals regularly. Set a rhythm of focused work and regular breaks so you get more done while saving your energy. With a non-distracting overview of elapsed and remaining time, Cucumber Timer helps you stay motivated, avoid distractions, and avoid sitting too long without a break. -- No ads -- Cucumber Timer helps you concentrate on what's important to you. Feature-rich for free: you can adjust focus and break intervals to reflect your preferences. Extra customization can be unlocked with a one-time payment: beautiful themes, specially recorded sounds, and a fixed brightness setting that helps the battery last longer. -- Adjust on the go -- Adjust remaining interval with 2 taps any time without affecting your usual settings. Sometimes you might have less time than usual, say you prefer to work for 25 minutes but now have just 10 before an appointment. Or perhaps you're feeling especially focused and would like to sit undisturbed for a longer time than usual. You can either select a new duration of the current interval (e.g., 20 minutes) or end time (finish at 15:30). -- Intuitive visual time -- The interval rings make the current time immediately recognizable. You already have an intuitive feel for how many minutes a portion of a watch face represents — a quarter of an hour is a quarter of the circle, no counting needed. -- Customize display -- 8 beautiful dark color themes that are non-distracting, visually balanced, and readable. Choose to keep the screen always on as a reminder that you're focusing. Lower the brightness to make the battery last longer — or to stay discreet on your desk in an office or library. The in-app brightness slider holds your chosen level whenever Cucumber Timer is in the foreground, so you don't have to adjust it by hand each time. -- Save battery -- Minimal battery use in the foreground; none in the background. When you start an interval, Cucumber Timer schedules notifications for upcoming focus and break intervals — no code running in the background to drain your battery. -- Choose sounds -- Choose whether the app plays a sound, vibrates, or stays silent when an interval starts. 19 unique sounds recorded specifically for Cucumber Timer.

Verdict
The clearest difference is in-app purchases: One at none against Cucumber Timer's 1. One also leads on iOS requirement (12.0 vs 15.0). Cucumber Timer's advantage is update cadence (every 9 days vs every 23 months). On price, review sentiment, ads and device support there is nothing between them.
