Lifestack
What is Lifestack?
Lifestack is a productivity planner that builds your daily schedule around sleep, recovery, and focus instead of empty calendar blocks. It reads wearable and health signals, maps energy peaks and calm periods across your day, and drafts a schedule that places demanding work when you can actually focus.
Most calendar apps treat you like a task executor with unlimited stamina. Lifestack treats energy, meals, and rest as first-class inputs, overlaying focus and calm zones on your calendar so you see when deep work fits and when lighter tasks make sense. That body-first layer is the trade-off: it is narrower than a general project manager, but it connects health data to scheduling decisions most planners ignore.
The product suits professionals juggling meetings and deep work, ADHD users who need external structure around energy swings, and anyone syncing tasks from tools like Trello while trying to protect sleep and meal timing. Apps run on iPhone, Mac, Android, and Chrome, with a desktop Mac download and browser extension for calendar access.
Rejoy
What is Rejoy?
Rejoy bundles shared calendars, tasks, shopping lists, meal plans, notes, and encrypted family chat into one mobile app from Xily. The App Store listing describes AI family assistants that answer parenting, cooking, and finance questions, plus recipe and meal-plan generation based on preferences and allergies. Families sync personal calendars into a shared view with color-coded events and reminders.
Unlike single-purpose list apps, Rejoy merges organization and messaging in one feed. You can assign chores, build grocery lists, store recipes, and run weekly meal plans without switching tools. That combined layout suits households that want planning and conversation in the same place, even if it adds complexity for users who only need a calendar.
Parents and caregivers are the core audience. The iOS app remains on the App Store, while third-party trackers report the Android listing was removed in mid-2025. Reviews mention a free trial before subscription features unlock.
