Baby's First Signs

Teach calm baby sign language—before the words catch up.

Everyday needs show up long before speech does: milk, more, sleep, all done. Baby's First Signs helps parents learn a first set of signs with confidence—not pressure—and use them in real moments with baby.

Start with a free parent guide, explore 29 first signs with clear demos (including angle views so you can mirror the motion), then lock it in with short practice quizzes and a simple streak. Soft design for tired parents. Core learning works offline. No account required.

Practice quizzes, favorites, and streaks that stick
Educational companion—not medical advice or speech therapy

Under-Pressure Cooker

Find a food. Get the cook time. Follow short steps.

Pressure cooking should not mean guessing. Under-Pressure Cooker covers 100+ foods—beans, grains, meat, seafood, vegetables, fruit—with times after the cooker is at pressure, plus adjustments when frozen, dry, soaked, or portion size actually matters.

Browse or search, pin favorites and recents, expand steps when you need more detail, and set optional phone reminders for cook or natural-release waits. Multiple food timers at once. Weight and volume units. Core times and steps work offline. No account. English, Chinese, Hindi, Spanish, and Arabic.

CoTimer

Live shared timers—with status the whole house can see.

Laundry, the oven, pickup windows—someone always thinks someone else is watching the clock. CoTimer keeps one countdown on every phone, then shows live status on the card: who's still on it, who marked Can't, who Snoozed, and who tapped Done.

Each run keeps a real activity log. History filters Done, Missed, Snoozed, and Can't so handoffs aren't a guess. Free early access for households and partners—web app live now; store listings when they ship.

Live Can't and Snooze status on every shared timer
Done confirmation, group snooze, and personal remind
Per-run logs and filterable household history
Partner and household groups with multi-device sync
