Water climbs. Sand falls. A picture appears. Flow Timer is a visual timer: it shows you time instead of telling you. Water that climbs the glass as you go, a sand timer whose grains really fall, or a picture that paints itself while you work. Glance at it and you know how long is left — no numbers to read, no arithmetic. BUILT FOR TIME BLINDNESS When minutes feel invisible — as they often do for people with ADHD — a shape you can watch beats a number you have to interpret. That is the whole design. Nothing flashes, nothing nags, nothing demands a decision. The timer simply keeps being visible until it is done. A TIMER WORTH LOOKING AT Most timers are ugly because nobody expects you to watch them. This one is made to be watched: hand-drawn scenes, five colour palettes, an hourglass with real falling sand, calming sounds, and a zen mode that clears away everything but the time. Leave it running on a desk or a second screen and it earns its place. IN THE CLASSROOM AND AT HOME Big enough to read from the back row, clear enough for a child who cannot read a clock yet. Transitions, tests, quiet reading, toothbrushing, screen time, bedtime wind-down. A visual countdown ends the "how long left?" question without anyone having to answer it. ALSO A GOOD STUDY TIMER Set any duration, name it, start it in one tap. Build interval sessions for pomodoro study blocks, workouts or circuits. Streaks, badges, a heatmap and monthly trends record where your focus actually went, from your very first session. OFFLINE, AND STAYS THAT WAY No account, no sign-in, no analytics, no ads. Flow Timer collects nothing about you because it has nowhere to send it — everything stays on your device unless you export a backup yourself. Available in 15 languages. ONE PURCHASE, NOT A SUBSCRIPTION Free covers the liquid mode, the sand timer, intervals, every duration, most sounds and your daily statistics. Flow Timer Pro is an optional one-time purchase — never a subscription — adding canvas timers with your own photos, binaural beats and focus tones, your complete history, and backup export. Buy it once and it is yours for good. Built by one person who wanted a timer worth looking at.

Solar Empowerment: The Compass of Biological Truth Not a bio-hack, tracker, or coach—this is a compass of truth for the undeniable solar and biological forces that govern human performance. While your habits may fluctuate, the rhythms of the sun and your internal master clock remain constant. We map these certainties to give you a clear window into your natural biological potential. Solar Empowerment uses your exact GPS location to calculate precise solar phases. By mapping the physics of the sun to your SCN, the app shows you the objective truth of your biological alignment. No generic suggestions; just the math of your location meeting the reality of your biology. Suprachiasmatic Nucleus (SCN) - Your Internal Neuro-Biological Clock Your SCN is like a master conductor in your brain. It operates through the metronomic firing of neurons that trigger a precise cascade of neurochemicals and hormones at specific intervals. This molecular clockwork is triggered by the Solar Phases, and dictates your internal phases, ensuring every biological event happens in its optimal sequence. ———— SCN Phases These phases represent the specific biological shifts triggered by your internal clock. By understanding these transitions, you gain insight into the precise sequence of your body's daily internal cycle. The app evaluates how closely the Solar Phases and sunlight synchronise with your neurochemical timings. This identifies the moments where your environment and your biology are in perfect alignment, or where they have moved out of sync. • Waking Up • Cortisol Awakening Response (CAR) • Serotonin Surge • Chemical Stabilisation • High Activity • Low Activity • Melatonin Preparation • Go To Sleep Window ———— Brain States The influence of the SCN reaches beyond your physical and chemical rhythms; it also shapes your mental landscape. As your internal clock shifts your brain’s natural frequency, your cognitive ability for different types of tasks changes—moving you through distinct modes of thinking and awareness: • Theta - A State of Internal Focus. The timing for meditative thought, subconscious learning, and deep creativity. • Alpha - A State of Relaxed Awareness. The bridge between the subconscious and conscious mind, ideal for calm focus, flow, and creative problem-solving. • Beta & High Beta - States of External Focus. The timing for analytical logic, high-level alertness, and the execution of complex, demanding tasks. ———— Physiological Milestones Influenced by the SCN Phases, your body is naturally primed for specific physical and metabolic functions. By aligning with these physical and meal timings, you ensure your actions are supported by your internal chemistry: • Highest Alertness • Fastest Reaction Time • Best Coordination • Greatest Cardiovascular & Muscle Strength • Breakfast • Lunch • Dinner ———— Solar Milestones Using your exact coordinates, the app provides a detailed breakdown of the solar events for the day - giving context to understanding your environment: • Nautical Twilight Start & End • Civil Twilight Start & End • Sunrise • Solar Noon, • Sunset ———— 12-Month Summary All the Milestones and Phases offer a brief description, as well as their timings over 12 months, providing a long-term view of how NeuroBiological Rhythm fluctuates. ———— Apple Terms Of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
