iPhone Apps Keep Crashing? 7 Fixes That Work
When an app crashes on your iPhone, it closes instantly and dumps you back to the Home Screen. If it keeps happening — to one app or multiple apps — something is wrong with the app itself, your iOS version, or your phone's resources. These seven fixes are listed from easiest to most thorough. Most people solve the problem by Fix 3.

Why Do iPhone Apps Crash?
- Memory pressure: Your iPhone has a fixed amount of RAM. When too many apps or browser tabs are open, iOS kills backgrounded apps — and sometimes the one you are using
- Software bugs: A bad app update or iOS update can introduce crashes that the developer needs to patch
- Low storage: iOS needs free space to create swap files and caches. Below 1 GB free, apps become unstable
- Corrupted app data: An app's saved data or cache can become corrupted, causing it to crash on launch
- iOS/app version mismatch: Running an old app on a new iOS (or vice versa) can trigger compatibility crashes
Fix 1: Force Close the Crashing App
Force closing an app wipes its in-memory state completely, giving it a clean start on next launch.
- Swipe up from the bottom of the screen and pause in the middle (this opens the App Switcher)
- On iPhones with a Home button, double-press Home instead
- Swipe left or right to find the crashing app
- Swipe the app's preview card up and off the screen
- Wait 5 seconds, then reopen the app from the Home Screen
Important: Do not make a habit of force-closing all your apps constantly. iOS manages background apps efficiently, and force-closing them actually uses more battery when you relaunch them.

📋 Difficulty & Time
🔧 Diagnose & Fix Charging Issues: Step by Step
Step 1: Try a Different Cable AND Adapter
Cables fail more often than ports. Borrow a known-good cable from a friend, or grab a spare. Use a different wall adapter too — counterfeit chargers are a common silent killer.
Step 2: Inspect the Charging Port with a Flashlight
Hold the device under a bright light and look directly into the port. You're looking for:
- Gray pocket lint compressed against the back wall (most common)
- Bent or recessed pins (drop damage)
- Green corrosion on the contacts (liquid damage)
- Stuck-on residue from sticky drinks
Step 3: Clean the Port with a Plastic Pick
Power the device OFF first — this prevents short-circuits while you work. Then:
- Insert a plastic precision pick at a slight downward angle
- Work toward the back wall, then drag forward to pull lint OUT (never push deeper)
- Repeat from different angles — port lint is layered
- NEVER use metal — paperclips, needles, or pins will short the contacts
Step 4: Brush + Compressed Air
After picking visible debris, sweep the port with a soft anti-static brush, then short bursts (1 sec) of compressed air from 6 inches away. Keep the can upright to avoid propellant spray.
Step 5: Try Wireless Charging
If the device supports MagSafe/Qi: try wireless charging. If wireless works but wired doesn't, the port is dead — you need replacement (see escalation below). If wireless ALSO doesn't work, the issue is likely the battery or charging IC.
Step 6: Force Restart
Sometimes iOS/iPadOS gets stuck in a charging-block state. Force restart resets the power management chip:
- iPhone 8 and later: press Vol Up, then Vol Down, then hold Side until Apple logo
- iPad with no Home button: same as iPhone 8+
- iPad with Home button: hold Top + Home until Apple logo
⚠️ Common Mistakes to Avoid
- Pushing lint deeper instead of pulling it out
- Using metal tools (instant short risk)
- Skipping the cable test — cables fail more than ports
- Cleaning while the device is powered on
🏥 When to Call a Pro
If the port has bent pins, visible corrosion, or the contacts feel loose, you need a replacement (Apple: $129, third-party: $79–$99, AppleCare+: $99). Skip DIY for this — bent contacts can damage the logic board.
Fix 2: Restart Your iPhone
A restart clears all RAM, terminates every process, and reloads iOS fresh. If multiple apps are crashing, this is often the fastest fix.
- Press and hold Side button + Volume Down until the power slider appears
- Slide to power off
- Wait 30 seconds
- Press and hold the Side button until the Apple logo appears
After the restart, open the problem app immediately (before loading other apps) to give it maximum available memory.
Fix 3: Update the App
App developers push crash fixes constantly. If your auto-updates are off, you might be running a buggy version.
- Open the App Store
- Tap your profile icon in the top-right
- Scroll down to see Available Updates
- Tap Update next to the crashing app — or tap Update All
Pro tip: Read the "What's New" notes. Developers often mention "bug fixes" or "crash fixes" — that is your confirmation that the update addresses your issue.
To enable auto-updates going forward: Settings > App Store > App Updates toggle on.
Fix 4: Update iOS
Apple frequently patches iOS bugs that cause app instability. Running an outdated iOS version is one of the top reasons apps crash.
- Go to Settings > General > Software Update
- If an update is available, tap Download and Install
- Keep your iPhone plugged in and connected to Wi-Fi during the update
If you are several versions behind, expect a larger download (1-3 GB). Make sure you have enough free storage before updating.
Fix 5: Free Up Storage Space
Your iPhone needs breathing room. When storage drops below 1 GB, iOS cannot create temporary files and apps crash under pressure.
- Go to Settings > General > iPhone Storage
- Wait for the bar chart to load — it shows what is using your space
- Look at Recommendations at the top (like "Offload Unused Apps")
- Scroll down and tap on large apps to see their data usage
Quick wins to free space:
- Delete old text message threads with lots of photos/videos
- Clear the Safari cache: Settings > Safari > Clear History and Website Data
- Offload apps you rarely use (keeps data, removes the app binary)
- Move photos to iCloud or Google Photos, then delete local copies
Aim for at least 3-5 GB free for smooth performance.
Fix 6: Delete and Reinstall the App
If one specific app keeps crashing and updating it did not help, its local data may be corrupted. Deleting and reinstalling gives it a completely fresh start.
- Long-press the app icon on your Home Screen
- Tap Remove App > Delete App
- Open the App Store and search for the app
- Tap the cloud download icon to reinstall
- Sign back in and set up the app
Warning: This erases the app's local data (game progress, downloaded content, logged-in sessions). If the app syncs to a cloud account (like Spotify, Instagram, or Gmail), your data is safe — just log back in.
Fix 7: Reset All Settings
This is the nuclear option for software issues. It resets every setting on your iPhone — Wi-Fi, Bluetooth, notifications, display, privacy — back to factory defaults, without erasing your apps or data.
- Go to Settings > General > Transfer or Reset iPhone > Reset
- Tap Reset All Settings
- Enter your passcode
- Confirm — your iPhone will restart
What you keep: All apps, photos, messages, and files.
What you lose: Wi-Fi passwords, Bluetooth pairings, notification preferences, wallpaper, display settings, keyboard settings. You will need to reconfigure these afterward.
If Apps Still Crash After All 7 Fixes
- Check if the developer's servers are down — search Twitter/X for "[app name] down" or check DownDetector
- Your iPhone may be too old — some apps drop support for older hardware. Check the app's requirements in the App Store listing
- Hardware failure — in rare cases, failing NAND storage or a degraded battery causing throttling can cause system-wide crashes. A professional diagnostic can identify this
