Turn focused time into your own constellation. Explore Study Methods, build your star map, and unlock a more immersive experience with Anca Premium.
Turn focus into stars
Anca turns the time you spend focusing into something you can see and remember. Every completed session becomes a star in your personal constellation—a quiet record of the time you gave to what matters.
Find your rhythm
Choose a focus style that fits the way you work, whether you prefer structured focus-and-rest cycles or a more flexible session. Adjust your focus and rest times, start the timer, and let Anca keep the experience calm and simple.
Build your own star map
Each completed session adds another star to your constellation. Over time, your sky becomes a visual record of the time you chose to focus. There are no streaks, rankings, or points—only a record of the time you spent fully focused.
Stay immersed
Use optional app restrictions to reduce distractions while you focus. Anca’s quiet, deep-space interface keeps the timer at the center so you can stay with the task in front of you.
Lifetime Premium
Unlock the complete Anca experience with a one-time purchase. No subscription.
Premium includes Star Signature, Aurora Atmosphere, and more ways to look back on how your focus has grown over time.
Your focus. Your constellation.
Start with one session. Let the time you spend focusing slowly become a sky of your own.
