So you've installed Realwater — or you're about to — and you're looking at a sphere waiting to be filled. This guide walks you through your first week, one small step at a time. Not because the app is complicated (the whole point is that it isn't), but because a water habit settles in better when you add one piece at a time instead of configuring everything on day one. Here's the seven-day version.
First, what you're signing up for
The short version: not much, deliberately. Realwater is free on iPhone and Android. There's no account to create, no email to hand over, no onboarding quiz about your wellness goals — you open the app and you're in. Your data stays on your device; your drinking history isn't sitting on someone's server. The free version is supported by ads, and if they bother you, Premium removes them. That's the entire business model, so let's get to the water.
Day 1: set a goal you can actually hit
When you first open Realwater, it suggests a daily goal — a sensible starting point in the neighborhood of two liters, which is roughly where the science lands for most healthy adults. You can tune it, and you should feel free to: your right number depends on your size, your activity, and your climate. One honest tip for day one — if anything, err low. A goal you hit on a normal day beats an aspirational one you miss by a third, because in week one you're not really training hydration yet. You're training the habit of showing up, and hitting the target is what makes showing up feel worth it. You can always raise it later; many people do.
Day 1, continued: log your first glass
Now the fun part. Pour yourself a glass of water, drink it, and tap to log it. Watch the sphere: the water level rises. That's the whole core loop — drink, tap, rise — and it's deliberately the least demanding tracking loop we could build. No menus, no typing, no deciding. One tap per glass, and your day fills up in front of you. By tonight you'll have a number for how much you actually drank, which for most people is the first time they've ever had one. Day one's only job is done: goal set, first glass logged, sphere no longer empty.
Days 2–3: set up reminders around your real life
Now that logging feels natural, add the second piece: reminders. The trick is to schedule them around your actual day, not an idealized one. A reminder that fires during your daily stand-up gets swiped away and teaches you to ignore the next one, so think about where your dry stretches really are — for most desk workers it's mid-morning and the long slide from lunch to evening — and aim a gentle nudge there. Two or three well-placed reminders beat a dozen naggy ones. If notifications just aren't your thing, that's fine too: there are other ways to remember, and the sphere on your home screen is itself a quiet cue.
Days 4–5: make the servings match your glasses
By midweek you'll notice that your real drinking containers aren't the app's defaults. Maybe your desk bottle is 750 ml, your favorite mug is a small 200, and your kitchen glasses are somewhere in between — “a glass” is a surprisingly slippery unit. Take two minutes to adjust Realwater's serving sizes to match the two or three containers you genuinely use. This is the highest-value two minutes of setup in the app: once your servings match your reality, logging stays a single honest tap forever. Don't chase precision beyond that — close enough is genuinely enough for the decisions this data drives.
Days 6–7: read your first week
By the weekend you have something new: a real picture of your drinking. Look back over the week and hunt for the pattern rather than the grade. When do you fall behind? For most people the answer is the afternoon — mornings are carried by coffee and routine, then a gap opens between lunch and dinner. Wherever your gap is, that's where next week's effort goes: a reminder moved into the dead zone, a bottle filled right after lunch. One glass earlier in the gap usually does more than any goal adjustment. This is the quiet payoff of tracking — you're no longer guessing where the problem is.
A word about streaks (and missed days)
Realwater keeps a streak as you hit your goal on consecutive days, and in week one it's a lovely bit of momentum — day four feels meaningfully better than day three. Enjoy it, and hold it loosely. You will eventually miss a day: travel, illness, a Saturday that got away from you. That's not a failure state, it's a scheduled event in every habit's life, and the correct response is to log a glass the next morning and carry on. The streak exists to serve the habit, never the other way around. A missed day costs you a number; quitting over a missed day costs you the habit.
Beyond week one
That's the whole setup: a realistic goal, one-tap logging, reminders where your gaps are, servings that match your glasses, and a weekly glance at the pattern. From here the app should fade into the background of a habit that increasingly runs itself. If you find yourself enjoying the ad-free version of that, Premium removes the ads — but the free app is the full habit-building experience, on your device, with nobody's email address involved. Fill the sphere today, and let next week take care of itself.
