You jot something down mid-day, without stopping to pick a folder or a tag. Nyze handles the rest. You wrote "dentist Aug 28, 4pm" and later "John's birthday Aug 28, 4pm." Nyze catches the clash as you save and tells you. That's the kind of thing it does on its own. FREE, AND WORKS WITHOUT INTERNET • Write, record a voice note, or snap a photo straight from the home screen. • Make your own tags and sort things your way. • Search by word, offline. • A link is one tap to open. A phone number is one tap to save as a contact. NYZE PRO — 7 DAYS FREE • Automatic tags: every note lands in the right category, one tap to undo. • Clash alerts: two things booked at the same hour, and you hear about it first. • Automatic reminders: a date inside a note becomes a notification before it matters. • Dates become events: one tap puts it on your calendar. • Ask your notes: a straight answer, with the notes it came from. • Morning brief: the five things that matter today, at 8am. • Context before a meeting: what you wrote shows up 30 minutes ahead. • Old notes resurface: write about something and Nyze brings back what you already had. PRIVACY Your notes stay on your iPhone. Nothing is stored on our servers. Audio and photos never leave the device. On the free plan Nyze works entirely offline — none of your notes ever reach the internet. Pro features send only the note's text for processing, then discard it.

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.
