iPhone notifications: a morning summary of today’s tasks and all outstanding overdue tasks, plus due-time reminders and an adjustable summary time. Uses Vietnam time (UTC+7). Reminders update when you open the app or change tasks; changes from other devices take effect after syncing. Summaries are prepared up to 30 days ahead, with up to 60 upcoming notifications queued. Open the app regularly to renew reminders. LunarTodo helps you organize tasks and plan with both the solar calendar and the Vietnamese lunar calendar. • Quickly enter tasks in Vietnamese and review the date, time and priority before saving. • Follow Today, Inbox, the next 7 days, Calendar and Projects; search and filter by status. • Record purpose, desired outcomes, implementation notes, subtasks and journal milestones. • Create daily, weekly, monthly or yearly schedules; organize parent/child recurring rules and preview occurrences. • Choose solar or lunar dates, including leap-month and invalid-day rules. Lunar dates remain lunar dates instead of being converted only once to solar dates. • See full solar dates and localized sexagenary lunar year names. The interface supports 7 languages: Vietnamese, English, French, Russian, Simplified Chinese, Japanese and Korean. The free plan supports 2 projects (excluding Inbox), 10 recurring rules and unlimited ordinary tasks. Existing users receive a 30-day transition when the new limits take effect. LunarTodo Plus includes unlimited projects, unlimited recurring rules and no ads, with monthly or yearly subscriptions. Prices appear in the app for your store and region. Benefits sync when you sign in to the same LunarTodo account. Subscriptions renew automatically. If you cancel renewal, benefits remain until the end of the paid period. When returning to the free plan, choose which projects and rules stay active. Items above the limits are paused, not deleted, and remain available to view or export. The free plan may show banner ads. Task content, notes and project names are not shared with advertising providers.

Verdict
The clearest difference is ads: SimpleMind at none against LunarTodo's shown. SimpleMind also leads on iOS requirement (15.0 vs 17.0). LunarTodo's advantage is update cadence (every 2 days vs every 2 months). On price, in-app purchases and device support there is nothing between them.
