Turn your phone face down and focus. That time slowly becomes a piece of art. A focus timer for studying, exams, certifications, and reading. "I keep telling myself to study, but somehow I end up on my phone again." "Apps that just track study time with numbers and graphs never held my attention." "It's sad when all that effort leaves nothing behind." Time Atelier is a focus timer made for you. Two ways to start: tap a button, or turn your phone face down. With Face-Down Start, the timer keeps running while your phone stays face down, and pauses automatically the moment you pick it up. Leaving your phone alone helps you stay focused. Of course, you can also stick to the simple button-only mode instead (switch anytime in settings). And the time you focus never disappears. The artwork you choose—such as a terrarium or town festival—gradually takes shape as your focused time adds up. You'll see the first change after just 15 minutes. ◆ Key Features •Two ways to start: choose "Start with Button" or "Start Face-Down" •Face-Down Start: timing continues while your phone is face down, pauses automatically when you lift it, and resumes when you flip it back •Watch your art take shape: your artwork evolves step by step as focused time builds up, and finished pieces join your collection. New artwork is on the way, too •Complete two artworks for free: the short "Terrarium" and the longer "Town Festival" can both be enjoyed in full for free •Focus history: check your focus time today, this week, and this month, plus a chart of the last 7 days, for free •Widget: see your focus time today and your artwork's progress right on your home screen, no need to open the app •Completion cards: save and share your finished artwork as an image •Daily reminders: get a notification at a set time to help build the habit ◆ Who It's For •Middle school, high school, and college students building study time for tests and exams •Working adults preparing for certifications •Anyone who wants to protect real time for reading or creative work •Remote workers who tend to drift into distractions •Anyone who feels a bit too attached to their phone and wants some distance ◆ Your Records Stay on Your Device No account required.
