How do You Edit Cup on Plant Nanny?

Plant Nanny helps you stay hydrated by watering a virtual plant every time you drink. To get accurate tracking, you need to set the right cup size – that way each sip matches the water you actually drink. Editing your cup is simple once you know the steps, and this guide will walk you through every option.

How do I change my cup size in Plant Nanny?

Changing your cup size is the most common edit. Here’s how to do it on both iPhone and Android:

  1. Open the Plant Nanny app and go to your main plant screen.
  2. Tap the three horizontal lines (menu icon) in the top-left corner.
  3. Select Settings from the menu.
  4. Under the Drinking section, tap Cup Size.
  5. Choose a preset size like 8 oz, 12 oz, 16 oz, or 20 oz. You can also tap Custom to enter your own amount.
  6. Tap Save (or the checkmark) to apply the change.

After you save, every time you log a drink the app will use your new cup size. Your plant will grow at the same rate, but the water tracked will match your actual intake.

What if the edit cup button is not working?

Sometimes the cup edit option seems frozen or doesn’t respond. Try these fixes in order:

  • Force close and reopen the app. Swipe it away from your recent apps list and launch it again.
  • Update the app. Check your device’s app store for a Plant Nanny update. Older versions sometimes have bugs.
  • Restart your phone. A simple reboot clears temporary glitches.
  • Clear the app cache (Android only). Go to Settings > Apps > Plant Nanny > Storage > Clear Cache.
  • Reinstall the app. If nothing else works, uninstall and install again. Your plant data is usually saved in the cloud if you are logged in, but to be safe, sync before uninstalling.

If the button still isn’t working after all that, contact Plant Nanny support through the app’s help section.

Can I set a custom cup size instead of using presets?

Yes, absolutely. While Plant Nanny gives you preset sizes from 4 oz to 40 oz, many people drink from bottles or mugs that don’t match those numbers. To set a custom size:

  1. Go to Settings > Cup Size as described above.
  2. Tap the Custom option.
  3. Enter the exact number of ounces (or milliliters if your app uses metric) that your cup holds.
  4. Save the change.

If you don’t know the exact volume of your cup, fill it with water and pour into a standard kitchen measure. This step makes your tracking much more accurate. A simple measuring cup set (like these kitchen measuring cups) can help you check any mug or bottle.

Why should I adjust my cup size in Plant Nanny?

Getting the cup size right matters for three main reasons:

  • Accurate hydration tracking. If your cup says 8 oz but you actually use a 12 oz glass, you’ll under-report your water by 4 oz each time. Over a day that adds up to a big gap.
  • Plant health depends on real data. The plant grows based on the water you log, not how much you actually drink. If the numbers are off, your virtual plant might stay small even though you are well hydrated.
  • Goal setting becomes realistic. Plant Nanny lets you set a daily water goal. With the correct cup size, you know exactly how many sips you need to reach that goal. No guessing.

Taking two minutes to measure your favorite drinking vessel (like a reusable stainless steel water bottle) and update the app can make your entire hydration journey more honest and motivating.

How does Plant Nanny calculate water intake using cup size?

When you log a drink in Plant Nanny, the app adds the cup size value to your daily total. For example, if your cup is set to 12 oz, then every time you tap the water drop icon your intake increases by exactly 12 oz. The plant receives one full watering per drink logged, regardless of cup size – so editing the cup doesn’t change how often the plant gets watered, only how much water is counted.

The app also shows your daily progress towards the hydration goal. If your goal is 64 oz and your cup is 16 oz, you need 4 drinks. If you mistakenly have the cup set to 8 oz, the app would think you need 8 drinks to hit 64 oz, and you might over-log.

That’s why it’s a good idea to check your cup size every time you switch between different drinking containers – like a morning coffee mug vs. a big water bottle for the gym.

What other settings can I edit in Plant Nanny besides the cup?

Plant Nanny has several other customizable options. Editing your cup is just one part of making the app work for you. Here is a quick checklist of settings you can adjust:

SettingWhat it does
Drink goalSets your daily water target in ounces or milliliters.
Wake & Sleep timeLimits when the app reminds you to drink (so you aren’t pinged at night).
Plant typeChoose a different virtual plant (cactus, flower, tree, etc.) to keep things fresh.
Theme & backgroundChange the look of your plant environment.
Notification styleChoose between gentle alerts or more persistent reminders.
UnitsSwitch between Imperial (oz) and Metric (ml).

All of these are found in the Settings menu. Editing the cup size is the most important for daily accuracy, but adjusting your goal and wake hours makes the app fit your personal routine.

Does editing the cup affect my plant’s growth or history?

Changing your cup size does not reset your plant or erase its history. The plant keeps growing at the same rate based on how many drinks you log. Your daily and weekly water logs also stay intact – only the water amount per drink changes going forward.

If you previously logged drinks with a wrong cup size, you cannot go back and fix those past entries. But from the moment you edit the cup, all future logs will use the new size. To keep a consistent record, it helps to measure your cup once and stick with it, or change it only when you switch to a different drinking vessel.

For extra accuracy, consider using a dedicated water bottle that you keep at your desk or bedside. A time-marked water bottle makes it easy to see how much you’ve drunk, and you can set Plant Nanny to match that bottle’s exact volume.

How to delete or reset a cup in Plant Nanny?

There is no “delete cup” button in Plant Nanny. However, you can effectively reset the cup back to the default size (usually 8 oz) by following these steps:

  1. Go to Settings > Cup Size.
  2. Select the 8 oz preset (or whatever your app shows as default).
  3. Save the change.

If you had a custom cup size and want to remove it, simply choose a preset instead. The custom value will be replaced. There is no way to delete the custom number from the list – but once you switch to a preset, the custom size is no longer active.

For a full app reset (which erases all data including plants, history, and cup settings), go to Settings > Account > Delete Account. Use this only if you want to start completely fresh, because you will lose your progress and cannot undo it.

Most people never need to delete their cup – just editing it to the correct size is enough for accurate tracking. With the right cup size, Plant Nanny becomes a simple and enjoyable way to build a healthy drinking habit that works for you.
