Switching from Waterllama to P
If you’re rethinking Waterllama Premium, the lifetime subscription, or whether character-based logging is still doing its job, here’s an honest look at what changes when you switch to P.
Last updated: May 2026
What P does differently
P tracks hydration through bathroom visits instead of water intake. One tap per visit on iPhone or Apple Watch. Peer-reviewed research shows well-hydrated adults average 7±2 voids per day.
Why People Switch from Waterllama
Waterllama is a genuinely well-built app. It won the 2022 App Store Award, was a 2022 Apple Design Award finalist, and holds a 4.9-star rating across 147,000+ reviews. Anyone reading this who likes Waterllama is in good company. The reasons people consider switching are not about the app being bad. They are about the underlying approach starting to feel like work or stop feeling useful. The patterns we hear most often:
- Logging fatigue. The novelty of tapping a cup icon for every drink wears off after a few months. Once it does, missed logs accumulate, and a missing-data graph stops feeling motivating.
- The collection plateau. The characters are delightful at first. After you have collected a few dozen, unlocking the next one stops being the reason you open the app.
- Premium feeling cosmetic. Once you have the daily habit, the question becomes whether the extra characters and beverage types are paying off the way they did when you bought Premium or lifetime. Many switchers cancel Premium and never miss it.
- The measurement gap. Logging tells you what you drank. It does not tell you whether your body is actually hydrated. Two people can drink the same amount and have very different hydration depending on activity, climate, sodium, caffeine, and individual physiology.
- Wanting something simpler. A subset of users describe a feeling of, “I just want to know if I am drinking enough water, not curate a llama collection.” That preference grows with age and with the size of the existing log streak.
None of these are reasons Waterllama is wrong. They are reasons the fit may have changed. P solves a different problem with a different method, and the switching question is really whether that different method matches where you are now. The good news: P is free, the bathroom-based tracking and smart water reminders that matter most are not behind a paywall, and you can try it for a couple of weeks before deciding whether to keep paying for Waterllama Premium.
The Core Difference in One Paragraph
Waterllama tracks what goes in. You log every drink, the app estimates serving sizes, and an animated character fills with colored liquid as you reach your daily goal. P tracks what comes out. You tap one button each time you use the bathroom, and the app compares your frequency to peer-reviewed research showing well-hydrated adults average 7±2 voids per day. Waterllama tells you what you drank. P tells you whether it was enough. That is the entire trade.
Feature Parity: What Stays, What Changes
Here is what looks the same on both apps, and where the experience diverges. Use this as a switching map.
| Waterllama | P | |
|---|---|---|
| What you log | Every drink (beverage type + amount) | Bathroom visits (one tap each) |
| Time per log | 3–10 seconds (pick beverage, confirm size) | About 2 seconds (one tap) |
| Hydration measurement | Intake total vs daily goal | Visit frequency vs research-based range |
| Apple Watch | Yes (native app + complications) | Yes; 45%+ of P users log from Watch |
| iPhone widgets | Yes | Yes |
| Reminders | Throttled smart reminders for drinks | Smart reminders to drink water when you have gone too long since your last visit |
| Quiet hours | Yes | Yes |
| Data export (CSV) | No | Yes (with subscription) |
| Pee count calendar | No calendar view | Current and previous month free; older months with subscription |
| Beverage-specific tracking | 40+ beverages with hydration ratios | Not tracked (output reflects all sources) |
| Gamification | 100+ collectible characters, themed challenges | Streaks (consecutive healthy days) |
| Social / accountability | None | Hydrate with Friends: add friends, send hydration nudges, share a streak. Friends can also unlock subscriber features for each other. |
| Captures water from food and coffee | Only if you log it explicitly | Yes (output reflects all sources) |
| Medical voiding diary use | No | Yes (timestamped log doctors can review) |
| Platforms | iOS, iPad, Watch, Mac, Vision Pro | iOS, Apple Watch |
| Science backing | Beverage hydration index values | Peer-reviewed void-frequency research |
How to Switch (Without Burning Your History)
You do not have to commit to the switch on day one. Both apps can live on your phone, and trying P costs nothing. The cleanest path:
- Save your Waterllama history if you want it. Waterllama does not currently offer a data export. If you care about the record, take a screenshot of your weekly summaries before switching. Save them in Photos with a “Hydration history” album so they are searchable later.
- Download P from the App Store. Free, no signup. Tap once each time you go to the bathroom for the first day. You do not need to do anything else.
- Let P calibrate for a week. The first week is mostly about establishing your baseline. By day 5–7, the streak count, hydration assessment, and smart reminders start working off real data.
- Cancel Waterllama Premium once you’ve decided P fits. You can actually cancel today and still use Waterllama until the current billing period ends, so there’s no overlap cost. Subscriptions cancel from iPhone Settings › Your Name › Subscriptions › Waterllama › Cancel. Lifetime purchases cannot be canceled but cost nothing ongoing, so leave those installed.
If you decide P is not for you, deleting it has no cost and Waterllama is still right where you left it.
What You Give Up, What You Gain
What you give up
Characters and collection loop 100+ animated characters, themed unlocks, the feeling of completing a set. Beverage-specific tracking 40+ beverage types with hydration ratios. P does not differentiate water from tea from coffee. iPad, Mac, Vision Pro Waterllama covers the full Apple ecosystem. P is iPhone and Apple Watch only.
What you gain
A measurement of actual hydration Output-based assessment grounded in peer-reviewed research, not intake estimates. This part of P is free. Faster logging One tap, about 2 seconds. No picking beverages or estimating sizes. Captures all hydration sources Output reflects food water, coffee, tea, broths. Nothing to manually account for. Smart water reminders Free. They fire based on time since your last logged visit, not a fixed clock, so they only land when the gap is unusually long for you. Medical voiding diary use Useful if your doctor has ever asked you to track urination frequency. P doubles as a digital diary you can show at an appointment. Hydrate with Friends Add friends in the app, send each other hydration nudges, and stay accountable together. Friends can even unlock subscriber-only features for each other. There’s no equivalent in Waterllama, and it tends to be the part of P that users describe as actually fun. The option to stop paying Waterllama Premium Around $10/year back in your pocket. If P’s free tier is enough for what you need (it is for most users), you can let Waterllama Premium expire.
The trade is not better-vs-worse. It is intake-tracking-vs-output-measurement. The right choice depends on which question your body actually needs answered today.
The Research P Is Built On
If Waterllama’s beverage hydration ratios pulled you in because they felt scientific, here is the research P uses for the output-based approach.
Who Should Stay with Waterllama
Switching is not the right move for everyone. Stay with Waterllama if any of these describe you:
- The character collection is what keeps you logging, and you would lose the daily habit without it.
- You log a lot of specific beverages (tea, coffee, broth, sports drinks) and you want credit-adjusted tracking for each.
- You use Waterllama on iPad, Mac, or Vision Pro and that ecosystem coverage matters to you.
- You already have lifetime and have not run out of characters yet.
- You explicitly want intake tracking, not output measurement, because your goal is to drink a specific volume each day.
If none of those apply, P is worth a week of your time.

Try P Free Alongside Waterllama
Most of P is free, including the bathroom-based tracking and the smart water reminders. Tap once per bathroom visit for a couple of weeks. If the output-based picture lands cleaner than intake logging, you can let Waterllama Premium expire.
Frequently Asked Questions
It depends on what you want from a hydration app. Waterllama Premium unlocks 100+ collectible characters, 40+ beverage types with hydration ratios, themed challenges, and custom reminder sounds for around $10 per year. If you enjoy the gamified experience and the character collection is what keeps you coming back, that’s solid value. The unlocks are mostly cosmetic and motivational.
Premium does not change the core limitation that Waterllama tells you what you drank, not whether your body is actually hydrated. If the collection has stopped feeling fresh or you find yourself skipping logs, P takes a different approach: you tap one button each time you use the bathroom, and the app uses peer-reviewed research on void frequency to assess your hydration.
A lifetime purchase is worth it if you are confident the app will keep solving your problem for years. With Waterllama, that depends on whether character-based motivation will keep working for you. Many users find the collection loop fades after a few months once the novelty wears off, at which point the Premium features matter less.
If you already own lifetime, you have nothing to lose by trying P alongside Waterllama. P is free to download and use; both apps can coexist on your phone. If Waterllama’s logging interface has started to feel like work, that’s a sign the lifetime purchase may not be paying off the way it did when you bought it.
No. P does not import Waterllama data, and Waterllama does not export data in a format P can read. The two apps measure fundamentally different things: Waterllama tracks beverages you drank, while P tracks bathroom visits. There is no equivalent conversion between intake history and visit history.
If you want to keep a record of your Waterllama logs, take screenshots of your weekly summaries before switching. Most P users find that starting fresh with bathroom-based tracking is the cleaner path, because the metric is new.
Waterllama tracks what goes in. P tracks what comes out. You log every drink in Waterllama, the app estimates serving sizes, and an animated character fills up as you reach your goal. In P, you tap one button each time you use the bathroom, and the app compares your frequency to peer-reviewed research showing well-hydrated adults average 7±2 voids per day.
Waterllama solves the motivation problem with characters and challenges. P solves the measurement problem with output-based hydration assessment. Both apps are free to download. P also doubles as a digital voiding diary that doctors can use.
If the characters are the reason you opened Waterllama every day, yes. P has no character collection, no themed challenges, and no animated mascots. The motivation in P comes from a streak (consecutive days you stayed in your healthy range) and from seeing your bathroom frequency rise as your hydration improves.
Some people find the character loop is what kept them logging consistently and the switch does not work for them. Other people find that the characters had become a reason to log without thinking about whether logging was actually helping their hydration. Try P for a week before deciding. It is free and you can keep Waterllama installed.
Through your Apple ID subscription settings, not inside the Waterllama app. On iPhone, open Settings, tap your name at the top, tap Subscriptions, find Waterllama in the list, and tap Cancel Subscription. The subscription stays active until the end of the current billing period, so you do not lose anything by canceling today.
Lifetime purchases are not subscriptions and cannot be canceled or refunded after Apple’s standard refund window. If you bought Waterllama lifetime and have stopped using it, keep it installed: there is no monthly cost, and you can come back if character-based logging starts working again.
