## What is Exist?

THIS APP REQUIRES A PAID ACCOUNT. Signing up for a new account will start a 30-day free trial. After your trial, you can choose to purchase a subscription using in-app purchase if you wish to continue using Exist.

By combining manual tracking with automatic syncing from other services, we can help you understand and optimise your behaviour.

Track whatever you like. Bring your activity from your phone or fitness tracker, add other services like your calendar for greater context on what you're up to, and manually enter anything else you care about.

Track everything in one place

See numbers about things like your health, activity, productivity, social media, and local weather all together. Data syncs automatically from connected services, so your step count and time asleep are right next to manual data points, like your energy level and how many coffees you drank.

But it's not just about raw numbers. We deliver extra context like daily insights on how you're going, track long-term trends and averages, uncover relationships, and send it all in a weekly summary email too.

Which habits go together?

Correlations are the most powerful part of Exist. By finding relationships in your data, we can help you answer questions like:

    “What makes me happiest?”
    “What can I do to be more active?”
    “When am I most productive?”

Track anything you can think of

Some things in life can’t be counted by your watch or fitness tracker. With Exist, you can create your own data points to track anything else you want. Use it as a habit tracker, keep a record of medications and symptoms, or track subjective measures like energy and stress levels.

Run experiments on your behaviour, and Exist will confirm or rule out your hunches.You can enter data as a quantity, time period, scale from 1–9, percentage, or time of day. Or just add a tag to a day as a quick way to say "this happened".

We support the following Apple Health data from your iPhone:

* Steps, active minutes, floors, cycling distance, stand hours, active energy burned
* Sleep
* Food and water (energy intake, fat, protein, etc.)
* Workouts
* Heartrate (max., resting, average, HRV)
* Weight, body fat percentage, lean mass
* Mindfulness sessions
* Alcoholic drinks
* Sexual activity
* Menstrual flow

Other data you can sync from your iPhone:

* Location (Exist will use this to track weather data for you)
* Events from your calendar

Exist works best when connected to other services — add even more data by connecting any of these:

* Fitbit
* Oura
* Garmin
* Withings
* Strava
* RescueTime
* Todoist
* Toggl
* Instapaper
* GitHub
* iCal Calendars (Google, iCloud)
* Swarm by Foursquare
* last.fm
* Weather from Apple Weather

Take Exist with you on your iOS device and see all your metrics, wherever you are.

If you choose to continue using Exist after your free trial, you will need to purchase a monthly auto-renewing subscription. The current price for an Exist monthly subscription is 7.99 USD. Price will depend on your local currency. Payment will be charged to your iTunes Account at confirmation of purchase. Subscriptions automatically renew unless auto-renew is turned off at least 24-hours before the end of the current period. Your account will be charged for renewal within 24-hours prior to the end of the current period. You can manage your Subscription and turn off auto-renewal by going to your Account Settings after purchase.

### 5/5 — Nice app

*2026-05-11, version 4.2.11*

This app is lowkey underrated only found it through cahtgpt

### 1/5 — Warning

*2026-01-19, version 4.2.6*

Stay away from this app! 

I subscribed to this app for three months and entered my credit card details on their website. Shortly after I canceled my subscription, I noticed three unauthorized, unknown charges on my account totaling €150. I had never used this card for online payments before. I spent a long time researching and considering whether these payments could have been caused by me.

If you want to use the app, which otherwise works well, it's better to use Apple's in-app purchase option.

To the developers: Please check the security of your payment service providers.

### 1/5 — Good idea but bad execution

*2025-12-29, version 4.2.6*

The idea behind this is brilliant but it’s not all the way there. The inferences are accurate sometimes but many times says things that are just blatantly not true.

### 1/5 — Credit Card Details Up Front !

*2025-02-04, version 3.4.1*

They grab your credit card details before you can even use the app.  Not cool.

### 5/5 — This is the one

*2024-06-05, version 3.2.7*

I tried them all before I learned about Exist. This app has been incredibly useful, serving me up some very interesting correlations within the first 30 days. Everything is on a day-level granularity, which prevents me from the trap of capturing too much information, and the use of customizable tags and attributes make it very powerful. There’s not a whole lot you can’t do here, you can have it track whatever’s important to you. Do read the set up instructions and FAQ, and the ethos of this company to never share any data ever with third parties. 30 day trial means there’s no downside. I’m a huge fan.

### 5/5 — Great

*2024-01-29, version 3.2.7*

Having used exist since 2017, I can 100% say I wouldn’t be without it! 

Great app, great insights that get better as you gather more data.

### 5/5 — Best app for tracking health improvement.

*2023-08-18, version 3.2.1*

I just want to say thank you to the developers, this app has been so good to me. My apple watch will automatically sync a lot of my activities and right before bed time I will input my manual tracked attributes and its great! It has helped me realize that I am improving in my mental  and physical health. It allows you to look back and see where you may need to focus in order to achieve your goals. Its great to have these insights. Recommend for anyone working on mental and physical well being and/or trying to kick a habit.

### 3/5 — Lacking features

*2023-07-01, version 3.1.12*

It functions fine and is lightweight. You are unable to track custom text entries and it lacks proper tagging.

### 5/5 — Amazing, Life Changing App. Newest Updates Are Great

*2022-08-31, version 3.1.6*

This app can change your life. Don’t wait.

### 5/5 — I like the new custom attributes update

*2022-05-08, version 3.0*

Please keep working on features, well get multiple moods someday!
