BabyTracker

Built during naptime by a sleep-deprived dad - BabyTracker turns parenting chaos into a beautiful utility to track & monitor your little one's activity as a Family

Comment

Inspiration

When my daughter Dahlia was born, I quickly discovered that parenthood comes with more tracking than a NASA mission control center. You need to be precise about diaper changes, feeding times, quantities, and sleep schedules (what sleep?), my partner and I found ourselves frantically scribbling notes on napkins at 3 AM, to monitor our little one's activity.

As a project manager by day and a "please-just-sleep-for-two-hours" dad by night, I realized there had to be a better way than my wife's color-coded Excel spreadsheet (yes, she made one).

What it does

BabyTracker is the parenting sidekick you never knew you needed! It helps sleep-deprived parents track their little dictator's every move, mood, and bodily function with the precision of a Swiss watch. It also very intuitive.

From feeding schedules to diaper diplomacy, sleep pattern mysteries to growth milestones, BabyTracker turns the beautiful chaos of parenting into organized, shareable data. Because nothing says "I'm a responsible parent" like having charts and graphs of your baby's poop consistency! 📊

BabyTracker is social: this means you can invite your co-parent, care-givers, family members to follow and manage your babie's activity. This is the key feature that's behind paywall.

How I built it

  • Armed with nothing but determination to ship, an unhealthy amount of caffeine, and exactly 47 minutes of daily "me time" (usually during nap times), I embarked on a 2-month vibe-coding marathon.

  • The app is build with Expo (React Native) for cross-platform, powered by Supabase for DB, real-time sync, authentication, and designed with the aesthetic sensibility of someone who hasn't slept more than 3 consecutive hours in months but still believes in beautiful UX.

Challenges I ran into

  • Vibe coding is hard. I took (or did not took) some architecture decisions early one (Wrong expo version, files organization, not enough principles and guidelines to properly guide AI models) that I regretted down the line. Successful vibe coding will work only if you know where you are going, and if you can put together a plan you work along with AI models. Next time, I'll vibe code to prototype & design, and restart a new app from scratch when it's about the proper build.

  • Revenuecat integration. This was my first SaaS B2C app and my first experience with Revenuecat. I hard a had time set things up properly across Playstore & Applestore & Revenuecat. I was lucky Revenuecat just released a MCP, which was of great use to set things up properly.

  • Oh, and convincing my wife that "just one more commit" at midnight was essential for our daughter's future wellbeing.

Accomplishments that I am proud of

  • Successfully launched a full-featured app while maintaining a day job, a side project (I made esims.io), AND keeping a tiny human alive and happy
  • Created something that actually solves a real problem many new and repeat parents face
  • Managed to ship in under 2 months without any major mental breakdowns (just minor ones)

What I learned

Parenting is basically project management on expert mode with no clear requirements, constantly changing deadlines, and a stakeholder who communicates exclusively through crying.

Technical learnings:

  • Sometimes the best feature is the one that takes 3 taps instead of 5
  • Parents will pay for apps that save them time, sleep, or sanity
  • Real-time sync is not optional when multiple users are involved. Creating social apps is challenging technically.

Personal learnings:

  • I can code with one eye closed (literally)
  • Coffee is not just a beverage, it's a lifestyle

What's next for BabyTracker

World domination, one diaper change at a time!

Short-term goals:

  • Advanced AI features (Can we predict the next crying session? Science says maybe!)
  • Integration with smart home devices (IoT diapers, anyone?)
  • More visualization tools (turning baby data into better insights)

Long-term vision:

  • Expanding beyond tracking to become the ultimate parenting companion
  • Building a community of data-driven parents who proudly share their baby's sleep regression graphs
  • Proving that solo-founded B2C apps built during naptime can actually succeed
