App Name - OppRadar( Opportunity Radar )
Category — Business
1. Concept
OppRadar is a personalized opportunity discovery platform designed to help users never miss life-changing opportunities.
Ironically, many people who would benefit most from opportunities like this Bubble x Contra challenge may never discover them simply because they didn’t know they existed, found out too late, or were overwhelmed by scattered information online. OppRadar exists to solve exactly that problem — making opportunities visible, personalized, and actionable before deadlines are missed.
The vision for OppRadar goes beyond a hackathon prototype. With the right support, it can become a trusted platform helping students, builders, creators, and professionals consistently discover opportunities that change careers and lives. Winning this challenge would help kickstart that vision — improving discovery systems, expanding opportunity coverage, and making personalized access to life-changing opportunities more accessible globally.
The app intelligently curates opportunities such as:
Hackathons
Scholarships
Remote jobs
Startup funding
Fellowships
Grants
Open-source programs
Users select their interests during onboarding, and OppRadar creates a personalized feed tailored to what matters most to them.
Unlike many prototype-only experiences, monetization in OppRadar is implemented with an actual fully working payment infrastructure(Stripe), making the business model immediately testable and scalable. This creates a believable path to revenue while keeping the free experience useful and accessible.
2. Core Features
1. Personalized onboarding and interest-based recommendations
2. Fully functional Stripe-powered premium subscription flow(Video accompanied below)
3. Intelligent opportunity feed powered by selected interests
4. AI-inspired match scoring system for opportunity relevance
5. Deadline urgency indicators to prevent missed opportunities
6. Opportunity bookmarking and saved opportunities system
7. Detailed opportunity pages with direct application links
Monetization Strategy:-
OppRadar includes a real premium monetization system, powered by fully working integrated Stripe payments.
Premium members unlock:
1. Unlimited saved opportunities
2. Exclusive premium opportunities
3. Advanced opportunity access
4. Better personalized recommendations
Built fully using Bubble’s Native Mobile Editor as a polished, mobile-first experience for the Bubble Spring Hackathon.
The app was designed with scalability, personalization, and real monetization in mind from day one.

Hey 👋 I'm Memouna, just submitted Molo-Run to Bloom with Bubble. A mindful running coach with a Claude AI coach inside, built for people who find running intimidating. No shouting. Just movement 🌸
App name: MoloRun
Tagline: Slow running. Real progress.
App identifier: molo-run
Branch version ID: version-test
BubbleGo preview URL:
https://molo-run.bubbleapps.io/version-test/api/1.1/mobile/preview?debug_mode=true&preview_view=Splash
🙌 Short description:
MoloRun is a mindful running coach for people who find running intimidating. Simple run-walk intervals, no pace pressure, plus a personalized AI coach (Claude) that gives you encouragement based on how you actually feel after each session.
🚀 What it does
Most fitness apps shout at you to run faster, push harder, beat yesterday. Molo-Run does the opposite.
It's a mindful running coach built for everyone who's tried to start running and quit because the apps made them feel slow or behind. Molo-Run uses simple run-walk intervals, looped for around 30 minutes, so you build stamina at your own rhythm. No GPS shaming. No pace targets. No fitness-influencer energy.
After each session, you rate how you felt, not how fast you went. Anthropic's Claude reads your feedback and sends you a personalized coaching message: gentle, specific, and actually encouraging.
🤑Freemium with subscription (Molo+).
Free tier: onboarding, weekly schedule, the Easy Run program, and limited AI coach messages
Molo+ ($6.99/month or $29/year): unlimited AI coach with deeper personalization, advanced programs (5K, 10K, half-marathon), mood + pain trend analytics, custom intervals
🔥Why right now:
Spring is when most of us finally start moving outside again after winter. MoloRun meets you where you are, gentle, structured, and forgiving of bad days.
Built in 6 days on Bubble Mobile, powered by Claude🎉

love the designs for this!!
LoopIn - My entry for the @Contra HQ x @Bubble challenge! 🌿
Category - Communication
Concept
LoopIn is a hyperlocal social network that connects neighbors inside the same apartment building through a private community feed, a neighbor directory, and a simple invite code system.
The app gives every building its own space where residents can share updates, ask for help, offer things, and stay informed about what's happening where they live — without the noise of generic social media or chaotic group chats.
Inspired by the energy of spring, connection, and new beginnings, LoopIn encourages neighbors to step out of anonymity, meet the people around them, and build a small but real community starting from their own front door.
Core Features:
- Private building feed with 4 post categories: Alert, Help, Offer, Question
- Neighbor directory with floor and apartment details
- Invite code onboarding — residents join only with a verified building code
- Image support on posts
- Like and comment on every post
- Admin dashboard with pinned announcements
- Automatic subscription tier based on number of apartments
Monetization Strategy - LoopIn uses a building-level subscription model paid by the administrator. The plan is calculated automatically based on apartment count.
Plans include:
Micro — 1 to 20 apartments — 29 RON/month
Standard — 21 to 60 apartments — 59 RON/month
Large — 61 to 150 apartments — 99 RON/month
Complex — 151+ apartments — 179 RON/month
30 days free trial, no credit card required. Residents always use the app for free.
Why It Matters - Most neighbors don't know each other's names. There is no local app in Romania that solves this. LoopIn is the first hyperlocal building community app in a market of 4.5 million urban apartments, with zero direct competitors.
Built With Bubble - Built fully using Bubble's native mobile editor as a polished mobile-first experience for the Bubble Spring Hackathon.

App name: Flapchat
App Preview: LINK
Branch-version: test
Category: Communication
Flapchat is half chat app, half mobile game. You pick a courier — pigeon, snail, butterfly, eagle, bee — and your letter crosses the actual distance to your friend at that animal's pace. A pigeon to NYC might take eight hours. A snail across town might take only two days. Sometimes the courier doesn't make it at all.
Flapchat is slow on purpose, and watching a pigeon cross actual distance to your friend feels different — somewhere between sending a message and playing a small game.
Every courier has four stats: Speed, Reliability (the chance of arrival — a courier can always lose a message), Range, and Capacity (how many characters they can carry).
How it works:
1. Pair with a friend by code
2. Pick an animal courier
3. Write your letter
4. Watch it take off and then wait
Spring is migration season. Birds are crossing continents right now. So are your messages after sending them!
Progession & Monetization:
Players unlock new couriers by completing in-app challenges — that's the free progression layer. Paid wares live in the Outpost, a folk-magic trading post. Some buff a courier's stats; others unlock special effects. For example, the Rabbit's foot makes a courier 10% more likely to arrive.
Note: The app is fully functional and can be deployed into the app store as is.
this is so cute!
