Plenish
Creatine works. It just takes four weeks. Plenish gets you through the exact moment most people quit.
People quit creatine at the exact moment it starts working.
Creatine is one of the most studied supplements in existence — and one of the most abandoned. It takes about four weeks to build up in your body, and nothing feels different in the meantime.
Then week two arrives, and the scale goes up. It's water moving into your muscles — a sign it's working — but nobody told you that. So it reads as “I'm gaining weight,” and you quit right before the payoff.
A dozen apps will track your creatine with streaks and checkboxes. None of them tell you what's about to happen before it happens.
Not a tracker. A tank you're filling.
Plenish treats creatine the way your body does: a store you're topping up, not a habit you're maintaining. Each two-second daily log fills the tank a little more. Miss a day? That's not a broken streak — the tank just fills slightly slower. No guilt, no flames, no zeroes.
Around day 10, the app steps in before the scale moves and tells you what you're about to see and why it's good news. At day 28, the tank is full — and then the real question begins: does it seem to be working for the goal you named?
Four weeks, three beats
Log in two seconds
One tap a day. The tank fills visibly. A home-screen widget shows where you are without opening the app.
Get warned before week two
Around day 10, Plenish tells you the scale is about to move — and why that means it's working — before you see it and quit.
Reach full, then find out
Day 28: your tank is full. From there, the readout tracks whether creatine seems to be doing what you hoped it would.
Calm, honest, and quietly confident
Built around how the first month actually feels
