Eat Smart Kiwi is a food diary that finds patterns between what you eat and how you feel — including symptoms that show up hours later. It uses statistical machine learning on your logs to surface those correlations, then gives you personalised recommendations about which foods tend to help and which to be careful with. That is not a medical diagnosis, and large diet changes are still worth checking with a GP or dietitian.

You can usually get useful clues after a week, but we recommend sticking with it for at least a month to get reliable insights.

The more you track, the more value you get. It doesn't take much longer to track a few extra conditions, so we recommend tracking everything that interests you.

Your diary is stored in your Eat Smart Kiwi account, so you don't need to manually back it up. If you reinstall the app or use another device and sign into the same account, your diary will still be available. If you are using the app as a guest (not signed in), sign in first so your diary is saved to an account. Uninstalling without signing in can lose that data. If you also want a file copy, open Export Diary from the side menu and export as PDF or CSV.

No! Even if you don't have any ailments, you can still use it to identify foods that boost your energy, mood, work performance, or anything else you'd like to improve. And even the healthiest of people usually have the occasional cold or headache that they'd like to reduce.

Keeping a diary is completely free, with unlimited entries, including food, symptoms, sleep, exercise, notes, and other features. If you want insights and correlations about your data, then there is a small fee for a monthly or annual plan. There is a free trial for these plans and you can cancel at any time. You can find details on the profile screen.

On Android, go to the Profile screen and tap 'Manage subscription', then cancel in Google Play. On iOS, subscriptions are managed by Apple...to cancel a subscription, open the Settings app, tap your name, tap Subscriptions, tap Eat Smart Kiwi, then tap 'Cancel Subscription'. Note that deleting the app will not cancel your subscription.

Yes! As well as exporting your data to a PDF, you can also select the 'Share with Dietitian' option from the side menu and enter their name and email address. They can then create their own Eat Smart Kiwi account under that email address, if they don't already have one, and they will be able to view (but not edit) your data as if it were their own.

On the Diary screen, tap the + button (bottom right) and choose Add Food or Drink. Search for what you ate or drank, then save. You can also photo-log a meal, or use the in-app chat, for example “I ate toast” or “I drank coffee at 8am”.

Yes. You can log a meal from a photo, and photos are saved with the diary entry. On the Diary screen, tap the + button and choose Photo log food or drink. The app identifies the food and drink and adds them to your diary — tap the entry afterwards if you need to fix names or amounts. If you have turned on "Show quick log buttons on diary" in Settings, you can also use the camera button on the diary. On the iPhone and Android apps, you can also attach photos when adding or editing a food entry by tapping the camera icon (up to 4 photos). Photo logging includes a few free uses; after that it is a Pro feature. Typing food names with + is always free.

The diary shows one day at a time. On the Diary screen, tap the left arrow next to the date (it usually says Today) to go back to Yesterday, or tap the date itself to pick any day from the calendar. Then tap the + button and add food, drink, a checkpoint, or anything else as usual. Entries you add while viewing that day are saved to that day. You can also tap the date pill on the add-food screen and change it from Today to Yesterday. Or tell the in-app chat what you ate and when, for example “I had pasta yesterday at 7pm”.

Locate the entry in the diary. Tapping or clicking on it will open an edit dialog where you can change either the time or the contents.

Locate the entry in the diary and swipe right to delete it.

Yes! An exercise entry can be added using the icon on the main diary screen. If it does not appear in the initial list, select "more options". You can also connect with a Fitbit or other tracker.

To integrate with Fitbit, open the side menu and select "Connect to Fitbit". Follow the on-screen instructions to log in to your Fitbit account and grant Eat Smart Kiwi permission to access your Fitbit data. Once connected, your Fitbit data will automatically sync with Eat Smart Kiwi.

Currently, Eat Smart Kiwi can integrate with Fitbit. On Android, it can also import data from Health Connect, thereby connecting it to any other smartwatch or app that writes to this platform.

This can be done from the Fitbit app. Tap your profile picture (top right), then tap 'your data in Fitbit', then scroll down and tap 'Manage connected apps'. You should see a list of all apps that are syncing with Fitbit, including Eat Smart Kiwi, and you can tap 'Revoke Access' to stop.

You can delete your account and all your data by going to Profile (accessible from the side menu), and then choosing Delete Account and Data. This will delete all your data from our servers, and you will no longer be able to access it or log in to Eat Smart Kiwi. Note that this will not cancel any active susbcriptions. If you want to keep your data but just stop using the app, then you can simply uninstall it from your device.

When you first create a check-in, you'll be prompted to choose conditions to track. You can edit this list at any time by going to Settings (accessible from the side menu), and then choosing Add or Remove Conditions.

Yes. You can swipe right on any of your tracked outcomes to remove them from the check-in.

If you just want to skip a condition on a single check-in, then swipe right to delete it. But if you want to stop tracking a condition on all future check-ins, go to Settings (in the side menu) and select Add or Remove Conditions. You can then add or remove conditions. This will not affect any existing check-ins.

Marking something as zero (great) means exactly that - you weren't experiencing any problems with it at that time. Our analysis will then look at your food and drink leading up to that time and assume that it helped rather than hindered your condition. If you simply delete a condition from a check-in altogether, that means our analysis will ignore the check-in altogether when analysing for that condition. Generally speaking, you should only delete a condition from a check-in if for some reason you don't know how to score it. For example, if you were filling in a check-in for last week, then you might not remember how bad your stomach pain was at the time. Or perhaps you would want to delete eczema from a check-in because you aren't able to examine your body for signs of it at the time.

Absolutely! That's how we can figure out which foods (or lack of foods) might have contributed to you feeling great.

Go to Settings from the side menu, then choose Add or remove conditions. Enter the name of the new symptom or condition. If it is not present in the search results, then you will see the option to create it as a new condition.

Whenever you want! However, we recommend adding a check-in at least once a day. It is also worth doing them after specific meals or activities that might influence your symptoms, and when you are feeling particularly good or bad. Remember to check-in when you feel good as well as bad, because this helps identify what contributes to positive outcomes as well as negative ones.

In the Insights screen, select the condition you are interested in. You will then see a graph showing how that condition has changed over time. You can also see a list of all the entries where that condition was tracked.

Don't worry if you don't get every last herb and spice in that curry. The more detail you provide, the better we can analyze it. But the most important thing is just to record *something*.

No. The more data you enter, the better we can analyze it. But we know and expect that you will miss things from time to time, and our analysis takes that into account.

Most people find it too time-consuming to record their water intake. If you suspect that your water intake is having an impact on how you feel, then it is worth entering it in, but otherwise it's fine to skip it.

Just an approximate time is fine. For slowly changing conditions, like acne, the time isn't important. For something more acute, like a headache, try to get it within an hour or two. The most important thing is to get the order of events right. We need to know if you drank that cup of coffee before or after you had that headache.

When searching for a food, if the food is not present in the search results, there will be an option shown to create it as a new food.

Yes! You can create a 'recipe' by selecting 'Recipes' from the side menu, and then tapping the '+' button. You can then add ingredients to the recipe. Recipes are only for foods that are normally eaten together as a meal — not for storing a sensitivity list, avoidance list, or bulk list of problem foods. Saved recipes appear in the normal food search when adding food to the diary — search using the recipe name, then select it. This automatically adds all the ingredients to your food diary entry. Recipes are private and only for your own use in the app. They are not public and are not shared with other users.

Eat Smart Kiwi does not currently use a predefined sensitivity or avoidance list for its analysis. Log the foods you actually eat and track symptoms you experience so the app can look for patterns in your own data. Recipes should only be used for foods that are normally eaten together.

To start with, all conditions contribute equally to the overall health scores. If you want to adjust this, you can do so from the Settings screen (accessible from the side menu).

The analysis looks at 6 different time windows: 1 hour, 3 hours, 8 hours, 24 hours, 72 hours and 168 hours (1 week). It considers all food and drink within the time window prior to the symptom. So if you had a headache at 3pm, and the time window was 24 hours, then the analysis will look at everything you ate and drank between 3pm yesterday and 3pm today. The time window with the strongest correlation is then used to calculate the score for that food or drink. This is how delayed effects such as digestion time are taken into account: a food that affects you hours later, the next day, or later in the week can still be linked to your symptoms. The chosen window is shown in Insights: on a food's insight page next to a clock icon, on the food-and-symptom detail page as scores in the subsequent X hours, and often on insight cards as "Within X hours of [food]...". This lookback window is not the same as the analysis period in Settings.

Yes. Eat Smart Kiwi does not assume a food only affects you right after you eat it. The model looks at how each food relates to your symptoms across many different time periods (1 hour, 3 hours, 8 hours, 24 hours, 72 hours, and 1 week before each check-in), then uses the period with the strongest pattern for that food and symptom. Delayed digestive effects — for example bloating or stomach discomfort hours after a meal — are part of the analysis, not ignored. It is not a medical test of gut transit time; it is a statistical look at which delays best match your diary.

Yes. This is a different setting from the correlation time window above. In Settings, choose "Adjust analysis period" to base Insights on all entries, or only on entries since a date you pick. That controls which diary days are included, not the 1 hour–1 week lookback used for each food–symptom pair.

Yes. Nutrients are calculated automatically from your food entries, so you do not log protein, fat, or carbs as a separate checkpoint. This includes calories, protein, total fat, carbohydrates, fiber, sugar, sodium, gluten, and several vitamins and minerals (vitamin A, vitamin B6, vitamin C, calcium, iron, potassium, magnesium, and selenium). On the Diary screen, a daily total appears at the bottom. Tap the nutrient name (it often starts as calories) to switch to protein, carbohydrates, total fat, or another nutrient. Tap the number to see a per-food breakdown for that day. On the Insights screen, when "Overall Health" is selected, there is a "Nutrients per day" section near the bottom with a chart of your intake over time. If you do not see nutrient totals, go to Settings and turn on "Track calories and nutrients". You can also turn on "Show daily nutrient totals in diary".
