How to track water intake on your phone (without only a watch)
Free printable blood pressure log (PDF)
How to track water intake on your phone is simpler than a watch workflow, because the water log in Blood Snap never waits for a wearable. You look at the glass, you tap the amount, and the diary keeps the millilitres. A watch can still be useful for steps or sleep. It is not part of tracking water here.
Blood Snap is a wellness diary, not a medical device and not a hydration coach. The steps below are how the Water log works. They are not instructions to drink a set volume. Use the daily goal your clinician gave you, or the number you already decided to aim for.
Track water on a phone, not only a watch
Some people assume intake tracking lives on a wrist: a complication, a bottle that syncs, or a watch app that guesses from motion. Blood Snap does none of that for water. There is no water read from Apple Health or Health Connect, and there is no bottle pairing. If you do not own a watch, you are not missing a water feature. If you do own one, water is still typed on the phone.
That split is useful. Steps, sleep, and resting heart rate can be read from the phone's health app when you turn those cards on, which is described in tracking steps, sleep, and resting heart rate. Water stays a deliberate tap so a guessed sip never lands in the diary.
Log a drink in under a minute
- Open Blood Snap and go to More Health.
- Open Water log. You land on the Log tab.
- Check the line today's ml / goal ml. A new diary starts with a goal of 2000 ml.
- Tap +250 ml (1 glass), +500 ml (Bottle), or Custom.
- For a custom amount, type the millilitres and add. Anything under 1 ml is ignored.
- Confirm the new row under Today's drinks. The time is the time you saved it.
Prefer the shorter path: on More Health, tap +, choose water, then pick 150, 250, 300, or 500 ml, or type another amount, and tap Add water. The success message shows the millilitres you added. The same entry appears in Water log.
If the glass was a mistake, open Today's drinks and delete that row. The day total drops by that amount. You cannot edit a row in place; delete and add again with the right number.
Glasses, bottles, and millilitres
The diary does not store a separate "glass" unit. The glass button is a shortcut for 250 ml. The bottle button is a shortcut for 500 ml. If your household glass is closer to 200 ml or 300 ml, use Custom so the total matches what you poured. The quick-add sheet on More Health also offers 150 ml and 300 ml chips, which helps when a glass is smaller or larger than the 250 ml default.
Coffee, tea, and water all go in as millilitres if you want them in this log. Blood Snap does not classify drinks, subtract caffeine, or split "water" from "other fluids." If your clinician asked you to count only plain water, log only plain water. The app will not enforce that.
Set the goal, then leave the phone in the kitchen
Tap Goal and enter a daily target of at least 250 ml. The bar fills as today's rows add up. When the total reaches the goal, the card reads Goal reached. Until then it shows the millilitres still to go. Turn on Show water on dashboard if you want the same total on Home without opening More Health. Logging once turns that switch on for you.
A watch is a poor place for this habit if you only remember at the sink. The phone is already in your hand, or it can buzz. Create a custom reminder named Drink water, daily, at the times you actually refill. When it fires, add the glass. The notification is a prompt you wrote. It is not proof that you drank, and it is not a clinical alert.
Look back without exporting every night
Switch to Analytics and choose 3, 7, or 30 days. You get days logged, average millilitres per day, the best day, how many days met the goal, and a Daily total chart in millilitres. That is enough for a personal check before a visit. If you need a file, Blood Snap Pro exports the visible period as PDF or CSV with the date, the amount in ml, and a notes column.
Use the same phone habit for the cuff. A water day and a blood pressure day are easier to remember when both start in one app. The measurement steps for the cuff are in how to log blood pressure at home. Weight, if you track it on the same mornings, stays in the weight and blood pressure log, not inside the water total.
What the phone diary will not invent
- It will not detect sips from motion, location, or a bottle sensor.
- It will not copy water into Apple Health or Health Connect.
- It will not recommend a new goal because yesterday was hot or because blood pressure changed.
- It will not mark you dehydrated. Goal reached only means the millilitres met the number you set.
