things

Do you feel like buying that thing you don't really need just because it's shiny and pretty and it will make you feel good? Stop for a second and spend a couple of minutes thinking if you really need that thing. Still, want it? If you don't buy that thing and you have it in your mind for some time (let's say 72 hours, 1 week, or 1 month) then you really want it. That's the thought behind fighting instant gratification. Instead of regretting buying that expensive thing in 1 week, why not do the opposite, and wait 1 week to really be sure you want it?

But wait, I need an app for that, because our lives are better with apps, right?

The "things" app is what you are looking for. Snap a picture of the thing, and select how much time you want to be reminded of not needing that thing.

Also, if you think you really want it you can use it as motivation to get some stuff done. Then, create tasks and link them to the thing you just added. Let's get some stuff done!
