This is exactly what I wanted to do. But I didn't know how. I looked into it with Stripe and they said they would have to authorize a payment every day and if this happens on a big scale it could trigger some bad stuff and lock it from working. Then I thought maybe I can create a community where if you don't post a message proving you did it this will trigger the transaction, but again it was very complicated. This is my first app and I am using off the shelf tools.

But hey, if you know how I could do this, please tell me and I am gonna do it.

About the charity I disagree, if the money goes to charity you will feel good about failing.

I don't know for sure if this would work, but it's pretty common for services to have a monthly subscription where the first month is free. You could maybe set up something like that, which either gets cancelled by you just after the end of the first month, or cancelled by the user at some point before then. (where "month" is some arbitrary duration)

I have been thinking about this as a "daily" habit kinda of thing, instead I think you're seeing it as a "monthly" goal kinda of thing. Maybe your view is easier so people don't have to subscribe and unsubscribe every day, but they can do so once per month.

So for example let's say I create a subscription, first month free.

My goal is to not drink alcohol for the whole month.

So let's say I do drink alcohol > I don't cancel the subscription and get automatically charged. If I don't drink it > I cancel it.

But then next month I would have to sign up again if I want to keep using this method let's say.

Will this mass subscribing and canceling on a daily/weekly/monthly basis annoy Stripe? I was reading from someone who did a similar app that 95% of people will say they achieved their goal. So that would be a 95% subscription cancellation rate.

also I don't want to have to deal with saving people's cards on my server for security headache reasons. So if you have a suggestion that takes this into account also, thanks!
