User: Build me a mobile app. edit
Build me a mobile app. The app will be called PBYSA Umpire Check-In. The purpose is for umpires to be able to submit that they were working. They should be able to create an account and login. Once logged in it will automatically fill in the date and time and it will ask them the following questions; What division? Are you the only umpire?
Assistant: Below is a solid MVP build for PBYSA Umpire Check-In: account creation + login + a “check-in” form that auto-fills date… edit
Below is a solid MVP build for PBYSA Umpire Check-In: account creation + login + a “check-in” form that auto-fills date/time and asks:
- What division?
- Are you the only umpire?
I’ll give you (1) the app flow/spec, (2) the backend/data model, and (3) working starter code using React Native (Expo) + Firebase (fastest way to get Auth + database without running your own server).
### edit
- Welcome - Buttons: Log In / Create Account
- Create Account - Email + password
- Log In - Email + password
- Check-In (main screen after login) - Auto-filled Date and Time (shows current local time) - Division (dropdown or text input) - Only umpire? (Yes/No switch) - Submit - Optional: list of your recent check-ins
- Settings - Log out
- Must be logged in to submit. edit
- On submit, save: - userId, email - timestamp (server-side if possible) - division - onlyUmpire (true/false)
Collection: checkins edit
Each document:
{
"userId": "abc123",
"email": "[email protected]",
"division": "10U",
"onlyUmpire": true,
"createdAt": "server timestamp"
}
### edit
- Install Node.js
- Install Expo CLI (optional; Expo also works via npx)
- Create a Firebase project (free tier is fine) - Enable Authentication → Email/Password - Create Firestore Database

In Firebase → Firestore → Rules, start with: edit
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /checkins/{docId} {
allow create: if request.auth != null

- Division as a dropdown list you control (8U/10U/12U/etc.) edit
- Add Field / Location, Game ID, Partner name (if not only umpire)
- Admin view for board members to export check-ins (CSV)
- Prevent duplicate check-ins within a time window (e.g., 2 hours)
- Push confirmation + “history” screen
If you tell me iOS, Android, or both, and whether PBYSA wants admins to see all check-ins, I can extend this into:
- an admin login role,
- an admin dashboard screen (inside the app),
- and/or a web admin panel for exporting payroll/assignments.
User: Make divisions a dropdown list. edit
Make divisions a dropdown list. Division are Teeball, 8U, 10U, 12U, and 15U. Add Field which is 1 through 8. Add a drop down asking if they are a solo umpire and the answer can be yes or no. Enable location and ensure they are within 5,000 feet of 2020 Bauer Road, Pensacola, FL 32506. Make for both iOS and Android. PBYSA wants admins to see all check-ins.
Assistant: Got it. edit
Got it. Here’s an upgraded both iOS + Android MVP using Expo (React Native) + Firebase with:
- Division dropdown: Teeball, 8U, 10U, 12U, 15U
- Field dropdown: 1–8
- Solo umpire dropdown: Yes/No
- Location enabled + distance gate: must be within 5,000 feet (~1524m) of 2020 Bauer Rd, Pensacola, FL 32506
- Admins can see all check-ins
For the location fence, I’m using the MapQuest listing for 2020 Bauer Rd which includes coordinates (30.38448, -87.40056). MapQuest[2]
From your Expo project folder: edit
npm install firebase expo-location
npm install @react-native-picker/picker
### edit
users/{uid}:
{
"email": "[email protected]",
"role": "umpire" // or "admin"
}
Each check-in document: edit
{
"userId": "uid",
"email": "[email protected]",
"division": "10U",
"field": 3,
"soloUmpire": "Yes",
"createdAt": "server timestamp",
"location": { "lat": 30.38, "lng": -87.40 },
"distanceMeters": 412.3
}
How to make an admin: after creating the account, go to Firebase Console → Firestore → users/{uid} and set "role": "admin".
In Firebase → Firestore → Rules: edit
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
function isSignedIn() {
return request.auth != null;
}
function isAdmin() {
return isSignedIn()
&& get(/databases/$(database)/documents/users/$(request.auth.uid)).data.role == "admin";
}
match /users/{uid} {
allow read: if isSignedIn() && request.auth.uid == uid;
allow create: if isSignedIn() && request.auth.uid == uid;
allow update: if isAdmin(); // admins can promote people
}
match /checkins/{docId} {
allow create: if isSignedIn()
&& request.resource.data.userId == request.auth.uid;

Expo builds both. edit
For local testing:
npx expo start
When you’re ready to ship:
npx expo install eas-cli
npx eas build:configure
npx eas build --platform ios
npx eas build --platform android
This app blocks submission on the device if the user is outside the 5,000 ft radius. For stronger enforcement (so someone can’t bypass it with a hacked client), the next step is a small Firebase Cloud Function that re-checks the location server-side and rejects invalid submissions. edit
If you want, I can add a simple Admin filter/search (by date, division, field, solo) and a one-tap CSV export workflow.
User: yes please edit
yes please
Assistant: Perfect — here’s Admin filter/search + CSV export added to the app still iOS + Android via Expo. edit
Perfect — here’s Admin filter/search + CSV export added to the app (still iOS + Android via Expo).
For the geofence center point, we’ll keep using MapQuest’s coordinates for 2020 Bauer Rd, Pensacola, FL 32506: 30.38448, -87.40056. MapQuest[4]

- Division filter (All + your list)
- Field filter (All + 1–8)

Right now the admin screen loads the most recent 500 check-ins and filters locally. This avoids Firestore “composite index” headaches and keeps the MVP simple. edit
If you expect more than that, the next upgrade is server-side filtering (Firestore where() queries + indexes) or a dedicated admin export Cloud Function.
If you want, I can also add:
- “Export All (last X days)” without loading them all into the app first, using a Cloud Function
- Admin-only user promotion screen (pick a user email → set role to admin)
User: add Admin-only user promotion screen edit
add Admin-only user promotion screen
Assistant: Yep. edit
Yep. Here’s an Admin-only User Promotion screen that lets an admin:
- Search exact email
- View the matched user(s)
- Set role to admin or umpire
This uses your existing users/{uid} docs and your Firestore rules already allow users updates only by admins.
Just confirming the key line is present: edit
match /users/{uid} {
allow read: if isSignedIn() && request.auth.uid == uid;
allow create: if isSignedIn() && request.auth.uid == uid;
allow update: if isAdmin();
}
Add the missing Firestore functions: edit
import { updateDoc, getDocs } from "firebase/firestore";
(Keep the existing imports you already have.)
### edit
This wraps two admin screens:
- Check-Ins (your current one)
- Users (new promotion screen)
Paste this entire block in place of your existing AdminScreen function. (Inside it, I kept your check-in filtering/export logic as a separate child component called AdminCheckinsPanel so it’s clean.)
function AdminScreen({ user, role }) {
const [tab, setTab] = useState("checkins"); // "checkins" | "users"

}
Take your current “filters + CSV export + list” admin screen code and wrap it like this: edit
function AdminCheckinsPanel() {
// paste your existing Admin check-in logic here
// (filters, exportCsv, FlatList, etc.)
}
Everything inside it can remain basically the same — just remove the outer <SafeAreaView> because AdminScreen already provides that.
Add these to your styles object: edit
adminTabRow: {
flexDirection: "row",
gap: 10,
marginBottom: 12,
},
adminTab: {
flex: 1,
paddingVertical: 10,
borderRadius: 10,
borderWidth: 1,
borderColor: "#ddd",
alignItems: "center",
backgroundColor: "#fff",
},
adminTabActive: {
borderColor: "#111",
},
adminTabText: {
fontWeight: "700",
color: "#666",
},
adminTabTextActive: {
color: "#111",
},
roleButtonRow: {
flexDirection: "row",
gap: 10,
marginTop: 10,
},
roleButton: {
flex: 1,
paddingVertical: 10,
borderRadius: 10,
alignItems: "center",
},
roleButtonPrimary: {
backgroundColor: "#111",
},
roleButtonSecondary: {
backgroundColor: "#fff",
borderWidth: 1,
borderColor: "#111",
},
roleButtonTextPrimary: {
color: "#fff",
fontWeight: "800",
},
roleButtonTextSecondary: {
color: "#111",
fontWeight: "800",
},
- This search is exact-match email on purpose (reliable + fast + no indexing hassles). If you want “contains” search, we can do a “starts with” approach (needs extra fields/indexing). edit
- Users must have signed up at least once so a users/{uid} doc exists (your signup flow already creates it).
If you paste your current AdminScreen (the one with CSV export) here, I can fold it in and return a single clean App.js with everything wired perfectly.
gpt-5-2 edit
User: I am done making this app. edit
I am done making this app. How do I use this code to compile it into an actual app?
Assistant: Great question — you’re at the “ship it” stage now 👍 edit
Great question — you’re at the “ship it” stage now 👍 Because you built this with Expo (React Native), compiling it into real iOS and Android apps is straightforward using EAS Build.
Below is the exact, production-ready path from code → App Store / Play Store.
✅ No Mac required for Android edit
✅ No local Xcode/Android Studio builds ✅ Safest + easiest
If you don’t already have one: edit
Then log in from your project folder:
npx expo login
====
npm install -g eas-cli ====
Verify:
eas --version
From your app folder: edit
eas build:configure
Answer the prompts:
- Android package name → org.pbysa.umpirecheckin
- iOS bundle identifier → org.pbysa.umpirecheckin
- Accept defaults for everything else
This creates:
- eas.json
- Updates app.json
Open app.json and make sure it looks like this: edit
{
"expo": {
"name": "PBYSA Umpire Check-In",
"slug": "pbysa-umpire-checkin",
"version": "1.0.0",
"orientation": "portrait",
"icon": "./assets/icon.png",
"splash": {
"image": "./assets/splash.png",
"resizeMode": "contain",
"backgroundColor": "#ffffff"
},
"ios": {
"bundleIdentifier": "org.pbysa.umpirecheckin",
"supportsTablet": false
},
"android": {
"package": "org.pbysa.umpirecheckin"
},
"plugins": [
"expo-location"
]
}
}
📌 Icons
- App icon: 1024×1024 PNG
- Splash screen: 1242×2436 PNG Place them in /assets.
### edit
eas build --platform android --profile preview
=====
eas build --platform android --profile production =====
Expo will:
- Upload your code
- Compile it
- Give you a download link
You can install the APK directly on phones for testing.
====
eas build --platform ios --profile production ====
During first build:
- Expo will ask to create iOS certificates
- Say YES to everything
⚠️ You must have:
- An Apple Developer Account ($99/year)
- The Apple account email ready
Expo handles certificates automatically.
### edit
- Download APK
- Install on phone
- Enable “Install unknown apps”
- Use TestFlight edit
- Expo can submit automatically (next step)
### edit
eas submit --platform android
You’ll need:
- Google Play Developer account ($25 one-time)
- App name, description, screenshots
=====
eas submit --platform ios =====
You’ll need:
- App Store Connect access
- Screenshots (Expo gives templates)
If you want to hide Firebase keys: edit
eas secret:create --name FIREBASE_API_KEY --value "xxx"
Then reference them in firebase.js.
- Android: Play Store listing or APK link edit
- iOS: TestFlight install or App Store listing
- Admin accounts: controlled inside the app
- Cloud backend: Firebase (no server to maintain)
Only do this if: edit
- You want full native control
- You’re comfortable with Xcode / Android Studio
npx expo prebuild
npx expo run:android
npx expo run:ios
(This is not recommended for first-time publishing.)
✅ Location permission text is correct edit
✅ Firebase rules tested ✅ Admin promotion works ✅ CSV export works ✅ Icons and splash screens added ✅ App name + bundle ID correct
- Store descriptions & screenshots? edit
- App Store privacy policy text?
- Firebase production rules review?
- Server-side geofence validation (extra security)?
Just tell me which one and I’ll handle it.
User: use this as the background for the app. edit
use this as the background for the app.
Assistant: Great — you can absolutely use that image as the app-wide background. edit
Great — you can absolutely use that image as the app-wide background. Here’s the clean, correct way to do it in an Expo / React Native app like yours.
I’ll show you exact steps and exact code.
1️⃣ Add the image to your project edit
- Create an assets folder (if it doesn’t already exist):
/assets- Put the image there and rename it something simple:
assets/pbysa-background.png(Expo works best with PNGs for backgrounds.)
2️⃣ Use it as the app background (recommended approach) edit
Instead of trying to set a “global CSS background” (which React Native doesn’t have), you wrap your screens in an ImageBackground component.
A) Import ImageBackground edit
At the top of App.js (or wherever your root screens are):
import { ImageBackground } from "react-native";
B) Create a reusable Background wrapper edit
Add this once near the top of your file:
function AppBackground({ children }) {
return (
<ImageBackground
source={require("./assets/pbysa-background.png")}
style={{ flex: 1 }}
resizeMode="cover"
>
{children}
</ImageBackground>
);
}
C) Wrap every screen with it edit
Example: Auth screen edit
Change this:
return (
<SafeAreaView style={styles.container}>
To this:
return (
<AppBackground>
<SafeAreaView style={styles.container}>
And close it at the bottom:
</SafeAreaView>
</AppBackground>
);
Do this for all major screens: edit
- AuthScreen
- UmpireCheckInScreen
- AdminScreen
- Loading screens
This ensures: ✅ Same background everywhere ✅ Works on iOS + Android ✅ No performance issues
3️⃣ Adjust container styles (important) edit
Because you now have a background image, remove solid white backgrounds so it shows through.
Change this: edit
container: {
flex: 1,
padding: 18,
backgroundColor: "#fff"
},
To this: edit
container: {
flex: 1,
padding: 18,
backgroundColor: "transparent"
},
Optional (recommended): Add a readable card overlay edit
Your UI already uses cards — keep them slightly opaque so text stays readable.
Example tweak:
card: {
borderWidth: 1,
borderColor: "#eee",
borderRadius: 14,
padding: 16,
backgroundColor: "rgba(255,255,255,0.9)"
},
This lets the logo show through subtly.
4️⃣ Optional: Darken or soften the background edit
If the logo is too strong visually, add a light overlay:
function AppBackground({ children }) {
return (
<ImageBackground
source={require("./assets/pbysa-background.png")}
style={{ flex: 1 }}
resizeMode="cover"
>
<View style={{ flex: 1, backgroundColor: "rgba(255,255,255,0.2)" }}>
{children}
</View>
</ImageBackground>
);
}
You can adjust 0.2 → 0.1 or 0.3.
5️⃣ (Optional) Use it for splash screen too edit
In app.json:
{
"expo": {
"splash": {
"image": "./assets/pbysa-background.png",
"resizeMode": "contain",
"backgroundColor": "#a7c9e8"
}
}
}
6️⃣ Test it edit
npx expo start
Check:
- Login screen
- Check-in screen
- Admin screens
- iOS notch + Android safe areas
Final result edit
✔ PBYSA logo visible across the app ✔ Professional, branded look ✔ No layout breakage ✔ Works on iOS + Android
If you want next:
- Logo watermarked instead of full background
- Different background for Admin vs Umpire
- Animated subtle background
- App icon generated from this logo
Just tell me 👍
