Three Apps Ready for the Play Store

This week we shipped three Android apps from concept to signed production builds. All three are built with Expo 54, React Native, and TypeScript — no backend required.

The Apps

HomeKeep — Home Maintenance Tracker ($4.99)

Tracks recurring home maintenance tasks like HVAC filter changes, gutter cleaning, and smoke detector batteries. Ships with 32 default tasks across 8 categories. Features notifications, completion history, and dark mode.

The existing apps in this space (Centriq, HomeZada, Dwellin) have mediocre ratings and limited scheduling. HomeKeep lets you set custom intervals — not just monthly or quarterly, but any number of days or weeks.

dBLog — Noise Complaint Tracker ($4.99)

A decibel meter that also logs incidents, looks up local noise ordinances, and generates court-ready PDF evidence reports. Uses your phone’s microphone to measure approximate dB(A) levels with a real-time SVG gauge.

This one fills a genuine gap — there’s no comprehensive noise complaint app on the market. 100M+ Americans are affected by noise issues, and 38% of tenant disputes involve noise. The app includes a bundled ordinance database covering the 25 largest US cities.

SaleFinder — Garage Sale Finder ($4.99)

Find and navigate to nearby yard sales and garage sales. Features a map view, 12 sale categories, GPS-sorted listings, nearest-neighbor route optimization, and Google Maps integration for turn-by-turn directions.

The market leader (gsalr/Garage Sale Map) pulled their Android app in February 2025, leaving a gap. The existing competition has poor UX and excessive ads.

Technical Stack

All three apps share the same foundation:

  • Expo 54 with React Native 0.81
  • TypeScript in strict mode
  • React Navigation bottom tabs
  • AsyncStorage or SQLite for local persistence
  • Dark mode with system detection
  • Signed with PKCS12 release keys
  • Both APK and AAB builds ready

What’s Next

Each app has a signed AAB, privacy policy, store listing copy, and step-by-step submission guide. The remaining steps are:

  1. Capture device screenshots for store listings
  2. Host privacy policies on GitHub Pages (blocked on griswoldlabs.com domain registration)
  3. Walk through Play Console submission for each app

Three paid apps at $4.99 each, no subscriptions, no ads, no backend costs. The goal is straightforward revenue from solving real problems with clean, offline-first tools.
