5 MVP Features Founders Waste Money On
Here’s a pattern I see constantly at WEBNUM: Founders come with an MVP budget, then halfway through development, they start adding features. Push notifications. Social login. In-app chat. Custom admin panels.
Every time, I have the same conversation: “These features will double your timeline and budget. And here’s the hard truth — none of them will tell you if people actually want your app.”
The pushback is always the same. “But all the big apps have these features!”
Yeah. They also have millions in funding and teams of 50+ engineers.
I’ve shipped over 100 mobile apps in the past 5 years. The pattern is clear: MVPs that succeed aren’t the ones with the most features. They’re the ones that ruthlessly cut everything except the ONE thing users desperately need.
Here are the 5 features that kill MVPs before launch — and what you should build instead.
Feature #1: Push Notifications From Day 1
“We need push notifications so users don’t forget about us!”
This is probably the most common request I hear. And it’s wrong for almost every MVP.
Why This Costs More Than You Think
Push notifications aren’t “just a plugin.” Here’s what you’re actually signing up for:
- Firebase Cloud Messaging (FCM) setup for Android
- Apple Push Notification service (APNs) certificates for iOS
- Backend infrastructure to trigger and manage notifications
- Testing across devices (many Android phones block notifications by default)
- User permission flows (which many users decline anyway)
- 2-3 weeks of development time
- $1,000-2,000 added to your MVP budget
The bigger problem? If users haven’t found value in your app yet, they’ll just turn off notifications. Or uninstall completely.
According to industry data, over 60% of users decline push notification permissions on first launch. For new apps with no established value, that number goes even higher.
What to Build Instead
Use email for your first 1,000 users.
Email is already where people check things. It’s non-intrusive, doesn’t require app permissions, and takes 1-2 days to implement with services like SendGrid or Mailchimp.
For task management apps, send daily email digests. For marketplace apps, send weekly updates. For social apps, send email when someone interacts with a user’s content.
Once you have 1,000 active users who open your app 3+ times per week, then consider adding push notifications. Not before.
Alternative: Build a simple in-app notification center (just a bell icon showing updates when users open the app). Takes 1-2 days to build in Flutter, gives users the feeling of being updated, and requires zero infrastructure.
Feature #2: Social Login (When Email Already Works)
“Users hate creating accounts. We need Facebook, Google, and Apple sign-in!”
Here’s what social login actually means for your MVP:
- Facebook Login: FB Developer account, app review, data privacy policies, constant API maintenance
- Google Sign-In: OAuth configuration, different implementations for iOS vs Android
- Sign in with Apple: Mandatory if you have other social logins, adding another integration layer
- Each method needs separate testing, error handling, and user support
That’s 3-4 weeks of development and $4,000-6,000 in costs for a feature that your first few hundred users will use once.
What to Build Instead
Simple email + password login using Firebase Auth or Supabase Auth.
Takes 1 day to implement properly. Add a “forgot password” flow using a pre-built template. Done.
Most users are perfectly fine with email login for new apps. The friction isn’t in the signup method — it’s in whether your app delivers value fast enough.
The only exception: If your core feature requires access to a user’s social media data (like “see which friends use our app”), then yes, you need social login. Otherwise? Skip it.

Feature #3: Complex Onboarding Flows
“We need to educate users about all our features with tutorial screens!”
If your app needs a 5-screen tutorial to be usable, your app is too complicated.
The average app loses 70% of users in the first 3 screens of onboarding (according to app analytics data from Mixpanel and Amplitude). Every extra screen multiplies that drop-off.
The Onboarding Mistake
I see founders build these elaborate flows:
- Welcome screen with value proposition
- Feature explanations with animations
- Permission requests (notifications, location, camera)
- Profile setup (name, photo, bio, preferences)
- “You’re all set!” screen
Users skip all of it. Or bounce during it.
What to Build Instead
Get users to your core feature within 30 seconds.
Look at successful apps:
- TikTok: You open it, videos start playing immediately. No account needed to watch.
- Instagram early days: Sign up, take a photo, add a filter, share. The app taught you by using it.
- Twitter: See tweets immediately, sign up only when you want to interact.
For your MVP:
- Optional welcome screen (can skip)
- Email signup
- Straight to the core feature
Ask for profile photos, location access, or friend invites AFTER users have experienced value. Use progressive disclosure — reveal features as users need them, not all at once.
Feature #4: In-App Chat
“Users will want to message each other in the app!”
Chat feels simple. It’s not.
What “Just Adding Chat” Actually Means
- Real-time messaging infrastructure (WebSockets or similar)
- Message persistence (database design for millions of messages)
- Push notifications for new messages
- Online/offline status indicators
- Read receipts
- Image/file sharing
- Moderation tools (you’ll need these fast)
- Blocking and reporting features
- Message search
- Group chat (users will ask immediately)
That’s not a feature. That’s building WhatsApp.
Development time: 4-6 weeks. Cost: $8,000-12,000. And you have zero proof anyone will actually use it.
What to Build Instead
Use existing messaging platforms.
For user-to-user communication:
- Add “Contact via WhatsApp/Telegram” buttons with pre-filled messages
- Use Intercom or Crisp for user-to-support chat
- Create a Discord or Slack community for your users
I’ve built marketplace apps where users connect on the platform, then move to Telegram/WhatsApp for project discussions. Development time: 3 hours. Users don’t complain because they’re already using these apps daily.
Once you have proven traction and validated demand for native messaging, then build it. Or use pre-built solutions like Stream Chat or SendBird that handle the infrastructure.
Feature #5: Custom Admin Panels
“We need a dashboard to manage users and content!”
You need to manage your data. You don’t need to build a separate web application to do it.
The Admin Panel Trap
Building a custom admin panel means:
- Separate web application with its own authentication
- Tables with sorting, filtering, search
- User management interface
- Content moderation tools
- Analytics dashboards with charts
- Export functionality
- Role-based permissions
That’s 4-6 weeks and $8,000-15,000 added to your MVP.
And here’s the reality: you’ll use it maybe 10 times in your first month when you have 50 users, not 50,000.
What to Build Instead
Use no-code admin tools that already exist:
Retool – Drag-and-drop interface builder connecting to your database. Build a functional admin panel in 2-3 days instead of 6 weeks. Free for small teams.
Forest Admin – Point it at your database, it auto-generates an admin panel. Works with PostgreSQL, MySQL, MongoDB.
Your database GUI – For the first 100 users, honestly just use PostgreSQL admin tools, Firebase Console, or Supabase Dashboard directly. Not pretty, but it works.
When you’re at 10,000+ users and these tools are limiting your operations, then build custom. Not before.
The Real MVP Framework: What You Should Actually Build
Here’s the framework I use for every MVP:
The One Core Action Rule
Your MVP should enable ONE core action perfectly. Not five actions adequately. ONE action that delivers immediate value.
- Airbnb: “Find a place to stay”
- Uber: “Get a ride now”
- Instagram: “Share a photo with a filter”
What’s yours? Build only what’s required for that single action.
The 80/20 Feature Cut
List every feature you want. Now cut 80%.
Yes, 80%.
If this feels uncomfortable, you’re doing it right. Your MVP should make you slightly uncomfortable on launch day. If you’re proud of every feature, you probably waited too long.
The “Use Existing Solutions” Checklist
Before building any feature, ask:
- Does a third-party service already do this well? (Usually yes)
- Can users accomplish this outside our app? (Usually yes)
- Will this feature directly validate our core hypothesis? (Usually no)
If you answered yes-yes-no, don’t build it yet.
