I’ve been drinking 3–4 coffees a day for years. At some point I realized caffeine just… stopped working. I wasn’t getting energy from it anymore, I just needed it to feel normal.

So I built CaffReset. Not an app to quit cold turkey — because that never works — but a 30-day gradual reduction down to zero, based on how caffeine withdrawal actually works scientifically.

How it works:

You start by telling the app how much caffeine you normally drink. It sets a daily limit based on that, then automatically lowers it a little every single day for 30 days until you hit zero. Your body adjusts slowly instead of crashing hard.

Logging is just your voice

You tap a mic button and say “I had two espressos” or “a Red Bull” and the AI figures out the caffeine amount automatically. No forms, no manual input. Takes about two seconds.

The plant

You have a little plant that grows as you stay under your daily limit. Stay consistent and it blooms by day 30. Go over your limit and it wilts a bit — but it never dies. No brutal streak mechanics, just a gentle visual.

Why gradual reduction and not cold turkey?

Research from Juliano & Griffiths (2004) and NIH shows that gradual tapering — reducing by roughly 10–25% every few days — significantly reduces headaches, fatigue, and mood symptoms compared to stopping abruptly. Cold turkey works for some people but most quit within 3 days because the symptoms are brutal.

The goal of the 30 days isn’t to never drink coffee again. It’s to reset your tolerance so that when you do have a coffee, it actually does something again.

Would love honest feedback from anyone who has tried to cut back on caffeine before. What made you fail? What would have helped?

I was thinking about making a coffein tracker app. My idea was: A minimalist caffeine tracker app featuring a living coffee cup mascot that fills up throughout the day based on your caffeine intake. The mascot changes mood and energy depending on how much caffeine is in your system. The goal is to stay in the optimal energy zone without overflowing the cup. My main question to you guys is how would you like to track your in take: scan your drinks, talk to an AI bot and tell him what you drank and then it estimates? What is the best? If you guys have any other ideas for the app i would love to hear them.
