Child milestone tracking, grounded in actual sources

DenLumen tracks developmental milestones, well-child visits, growth, vaccinations, and family gear for the children you're raising — every recommendation cited to AAP, CDC, and WHO. Same app you use for the family dog and cat. Free, no ads, no data sales.

What DenLumen tracks for your child

Developmental milestones

CDC and AAP-aligned milestones from birth through preschool. Not the cute version — the actual age-graded benchmark list.

Growth charts

WHO charts for 0–24mo, CDC charts after. Percentile tracking with notes on why one data point shouldn't panic anyone.

Well-child visit cadence

AAP-aligned visit schedule with vaccine, screening, and developmental-check reminders built in.

Photo journal with growth context

Photos timestamped against age. AI-drafted note suggestions you actually edit before saving.

Family gear board

Track baby gear purchases, registry items, hand-me-downs. Auto-import from Gmail order confirmations.

Digital wellbeing & first phone

Age-appropriate timing for the first-phone transition with curated recommendations like the Bark Phone for AI-monitored kids' phones, plus router-level screen-time and content controls.

Reference Library Q&A

Ask if it's normal that your toddler isn't pointing yet; get an answer with AAP citations, not a stranger's Reddit reply.

Privacy that's a feature, not a footnote

Most baby apps monetize by selling new-parent demographic data to baby-brand advertisers. DenLumen does not. We earn through affiliate purchases on gear we actively recommend (Lovevery, KiwiCo, Babylist, Bobbie for formula), and that is the entire business model. No third-party advertising profiles. No selling your child's data to anyone. Ever.

Data minimization. Firebase Analytics counts screen views; never identifies your child.
Account-level isolation. Other DenLumen users cannot see your data. Even operators cannot, without privileged access logged for audit.
Data export, anytime. Settings → Export downloads a JSON of everything you've ever entered.
Delete account, anytime. Settings → Delete account purges Firestore data + Storage photos.

One app for the whole household

If you're raising a dog, a cat, and a child in the same household, you currently use three different apps that each do their thing badly. DenLumen handles all three subject types with the same level of source-citation rigor. Add as many subjects as you need; switch context with a tap.

Free, no ads, no data sales

Open DenLumen and add your child. The first thing you'll see is an age-appropriate care plan and milestone timeline with AAP citations.
