TaskLens is the smart task manager that works the way your brain does โ speak it, paste it, or type it, and let AI do the rest. WHETHER YOU'RE MANAGING YOUR DAY OR BUILDING NEW HABITS TaskLens handles both. Create tasks in seconds with voice or AI extraction, then build lasting habits with streak tracking and flexible schedules. One app. Full picture. AI-POWERED CREATION Paste any block of text โ a message, email, meeting note, or browser article โ and tap "Extract with AI." TaskLens reads it and automatically fills in the title, due date, priority, category, reminders, and more. No manual entry. No copy-pasting. Just paste and go. Or skip typing entirely: use your voice, say the task out loud, and watch it appear in your list โ fully formed and ready to save. SMART REMINDERS THAT ADAPT TaskLens doesn't just ping you at a fixed time and call it a day. Its AI studies your tasks and sends motivational follow-up reminders tuned to how urgent and overdue each item is. Choose your notification intensity โ Low, Moderate, or High โ and TaskLens adjusts the tone and frequency to match your preference. Gentle nudges when you're ahead. Stronger pushes when you've been slipping. HABIT TRACKING Build lasting routines with built-in Habit Tracking. Set a habit, choose your schedule (daily, weekly, bi-weekly, or monthly across multiple days), add reminder times, and watch your streaks grow. Each habit tracks completions independently across every occurrence โ so missing one day doesn't erase your entire progress. Stay consistent. Stay motivated. RECURRING TASKS Real life repeats. TaskLens supports daily, weekly, bi-weekly, and monthly recurring tasks with independent per-occurrence completion tracking. Finish Monday's task without touching Tuesday's. Every occurrence is its own standalone check-in, so you stay in full control of your schedule without tangled dependencies. YOUR DATA, YOUR DEVICE Everything is stored locally on your device using a private SQLite database. No account required to get started. No data is ever sent to servers without your explicit permission. Your tasks, habits, and streaks stay private โ always. ICLOUD SYNC When you're ready to sync across multiple Apple devices, TaskLens uses your personal iCloud database. Your data is fully isolated to your Apple ID and never visible to anyone else โ not even us. Seamless sync without sacrificing privacy. CALENDAR & ANALYTICS See every task and habit at a glance on the Calendar view. Then switch to Analytics to track your completion streaks, category breakdowns, and weekly progress โ and get a clear, honest picture of what's working and where to improve. Spot your patterns. Optimize your week. SIRI INTEGRATION "Hey Siri, add task to TaskLens: Call dentist tomorrow at 10am." That's all it takes. TaskLens opens directly to a pre-filled task form ready for you to review and save. No context switching. No friction. WELLNESS REMINDERS Stay hydrated with reminders calculated from your body weight and the hours between your wake and sleep times. AI-generated hydration messages keep things fresh and varied so you never tune them out. EVERYTHING ELSE 5 recurrence types: Once, Daily, Weekly, Bi-weekly, Monthly Multiple reminder times per task or habit Priority levels with AI-suggested urgency Custom categories alongside built-in ones (Work, Personal, Health, Shopping) Light and dark themes Backup and restore via Google Drive or iCloud Share anything from Safari or other apps directly into TaskLens Offline-first โ works fully without an internet connection TaskLens Pro unlocks unlimited tasks, advanced AI features, full habit tracking, iCloud sync, and priority support.

ByWhen

A deadline is not just a date. It is a promise your future self needs help keeping. ByWhen helps you turn important tasks into practical reminder plans. Instead of relying on one alert, ByWhen looks at what needs to be done, when it is due, how long it may take, what kind of attention it needs, and when your day has realistic space for it. Add a task, set the due date, estimate the effort, choose the task type, and ByWhen helps you stay aware of the work before it turns into last-minute pressure. ByWhen is built for: - Work projects with real due dates - Assignments, exams, and study sessions - Calls, forms, paperwork, and admin tasks - Errands that need time away from home or work - Personal tasks that are easy to postpone - Daily, weekly, monthly, yearly, and selected-day routines DEADLINE PLANS ByWhen helps you think beyond a simple due date. It considers time remaining, estimated effort, task priority, task type, and available windows in your day. A short call can fit differently than a focused work session. An errand that requires leaving home can be treated differently from a quick task you can do during a break. REMINDERS WITH CONTEXT ByWhen keeps the deadline visible as time passes. It highlights whether a task is on track, needs attention, is at risk, or has become critical. If you do not act on a reminder right away, the task remains part of your plan so you can return to it later. OPEN-TIME PLANNING With your permission, ByWhen can use calendar busy blocks to avoid suggesting times that are already occupied. You can choose what to include, ignore imported blocks, and keep control of your schedule. ROUTINE SETTINGS Set your wake time, sleep time, work hours, and workdays so reminder timing fits your real life. ByWhen can avoid unhelpful times and protect parts of the day when reminders would not make sense. TASK TYPES Different tasks need different kinds of time. ByWhen supports task types such as focused work, admin, calls, study, errands, and away-from-home tasks. This helps ByWhen suggest more realistic moments instead of treating every reminder the same way. REPEATING TASKS Create repeating tasks for daily, weekly, monthly, yearly, or selected days of the week. When you complete a repeating task, ByWhen moves the next cycle forward so you are not reminded again for the period you already finished. QUICK ACTIONS Act from a reminder when possible. Start work, be reminded later, log time, or mark the task done so your plan can stay up to date. PRIVATE BY DESIGN ByWhen is built with privacy in mind. Your tasks, schedule blocks, routine settings, and reminder plans stay on your device. No account is required to start. If you choose to export a backup, it goes to your own selected destination. BYWHEN PREMIUM Your first 7 days are ByWhen Premium. During this time, all smart planning features are available. ByWhen Premium keeps every reminder active and unlocks the full planning experience, including unlimited active reminders, deadline plans, open-time planning, task-specific reminder styles, repeating tasks, quick actions, and routine personalization. After the first 7 days, your reminders stay safe, but Premium is required to keep all smart reminders active. Download ByWhen and give your deadlines a plan you can trust.
