There's a tiny cactus living on your phone — and right now, it's thirsty. Every glass of water you drink brings it back to life. Skip your water and it slowly wilts; hit your daily goal and it stands tall, blooming and proud. Cactus turns drinking water into a habit you actually want to keep — because nobody likes to see their cactus sad. A MASCOT THAT MIRRORS YOUR DAY Your cactus has 5 moods, from bone-dry to thriving. It follows your hydration in real time: every drink you log perks it up a little. And each morning it wakes up thirsty again — your daily little reason to drink water. A WATER GOAL MADE FOR YOU No generic "8 glasses a day". Cactus calculates your daily water intake from your weight, your activity level and your climate — so you drink toward YOUR number. Prefer to pick your own target? You can. EVERY DRINK COUNTS — JUST NOT EQUALLY Water, tea, coffee, juice, milk, smoothies, sparkling water… each drink has a real hydration value. Coffee only counts half, and (sorry) alcohol counts zero. Your progress reflects what your body actually gets. REMINDERS THAT NUDGE, NEVER NAG A water reminder at the pace you choose, only between your wake-up time and bedtime. No guilt trips, no buzzing at 3 AM — just a friendly nudge to drink water. ALSO IN THE POT • Log a drink in two taps, with quick-add amounts • A drink-by-drink timeline of your day, plus your best-day record • Daily streak and weekly hydration stats • Light, fast, works offline — no account, no sign-up • Your data stays on your phone FREE, WITH A SIMPLE DEAL Cactus is free to use, supported by ads. The optional Premium upgrade just removes the ads — every feature stays free for everyone. Whether you're looking for a water reminder, a simple water tracker, or just a little green friend who cheers every time you hydrate — Cactus is waiting for you. Fair warning: it's a bit thirsty.
