Nice app

This app is lowkey underrated only found it through cahtgpt

Warning

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.

Good idea but bad execution

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.

Credit Card Details Up Front !

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

This is the one

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.
