Your morning routine — and every other routine in your day. Build any routine or habit — morning, evening, gym, study, wind-down — and put a real tool behind every task instead of a checkbox. DESCRIBE IT, SIOLY BUILDS IT Say what you want in one line. The AI assistant asks a few questions and builds the whole routine: tasks, times, repeats. BUILD IT EXACTLY HOW YOU WANT Drag tasks and widgets into your day. Sizes, order, what you see first — yours. A REAL TOOL BEHIND EVERY TASK A task is not just a line you tick. Add a Guided To-Do and the task opens a full tool: a food scanner with macros, a gym log with sets and weights, a journal with a mood check, a run tracker with a live map, a focus timer, an alarm clock, notes, a task list, recipe packs, and your calendar. AND MOST OF THOSE TOOLS ARE FREE The alarm clock, focus timer, journal, notes, task list, run tracker and calendar cost nothing. Premium adds six flagships. YOUR REAL CALENDAR, INSIDE YOUR PLANNER Add the calendar tool and your actual events sit next to your routine — iCloud, Google, whatever is already on your phone. Create, move, edit and delete them without leaving Sioly, so the day you planned and the day you booked are the same day. IT RINGS WHEN IT SHOULD Set an alarm, and run a focus timer that rings when the time is up. On iPhone the timer keeps counting on the Lock Screen with a Live Activity, and on iOS 26 the alarm rings through Silent and Focus the way the system clock does. START FROM A ROUTINE THAT WORKS Seven proven templates — morning, evening, strength, cardio, meal prep, deep work, Sunday reset. Use one as it is or take it apart. Four are free; three are part of Premium. TRACK EXACTLY WHAT MATTERS TO YOU Pick the statistics you care about and build your own progress board. TOGETHER Join a group, chat, and see each other's streaks on the leaderboard. IN YOUR LANGUAGE English, German, Spanish, French, Italian, Portuguese, Dutch, Japanese and Chinese. SIOLY PREMIUM Sioly Premium unlocks the AI assistant, the food scanner, the gym log, the workout video module, the breakfast and dinner recipe packs, three routine templates, and step tracking on iPhone. It is an auto-renewing subscription, monthly or yearly. The price for your country is shown in the app before you confirm, and you can cancel any time in your account settings. You can try the AI before you subscribe. Terms of Use: https://sioly.app/terms Privacy Policy: https://sioly.app/privacy
