# App Performance Issues

> Help with app slowness, crashes, high memory usage, and general performance problems.

If High IQ feels slow, crashes unexpectedly, or uses excessive battery or memory, this guide covers the most common causes and how to resolve them.

## Common Causes

<AccordionGroup>
  <Accordion title="App is slow or laggy">
    **Symptoms:** Screens take a long time to load, scrolling is choppy, or tapping buttons has a noticeable delay.

    **Solution:**

    <Steps>
      <Step title="Update the app">
        Performance improvements are included in most updates. Open the **App Store**, search for "High IQ," and install the latest version.
      </Step>

      <Step title="Restart the app">
        Force-close High IQ from the app switcher and reopen it. This clears temporary memory and resets internal caches.
      </Step>

      <Step title="Free up device memory">
        Close other apps running in the background. If your device has many apps open simultaneously, iOS may throttle performance.
      </Step>

      <Step title="Restart your device">
        A full device restart clears system-level memory pressure that can slow down all apps.
      </Step>
    </Steps>

    <Info>
      The Strain Discovery screen loads thousands of strains with real-time search and filtering. If this screen feels slow, it typically improves after the initial data load is cached.

  </Accordion>

  <Accordion title="App crashes on launch or during use">
    **Symptoms:** The app closes unexpectedly, returns to the home screen, or shows a white screen before closing.

    **Solution:**

    <Steps>
      <Step title="Update to the latest version">
        Most crashes are caused by bugs that have already been fixed. Check the App Store for updates.
      </Step>

      <Step title="Check iOS version">
        High IQ requires **iOS 16 or later**. Go to **Settings > General > Software Update** and update if your version is below 16.
      </Step>

      <Step title="Free up storage space">
        If your device has less than 1 GB of free storage, apps may crash due to insufficient space for temporary files. Go to **Settings > General > iPhone Storage** to check.
      </Step>

      <Step title="Reinstall the app">
        Delete High IQ and reinstall it from the App Store. This removes any corrupted local data. Your account data is stored in the cloud and will sync back after you sign in.
      </Step>
    </Steps>

    <Warning>
      If the app crashes immediately on launch every time, reinstalling is usually the most effective fix. Your stash, sessions, favorites, and reports are all stored in the cloud and will not be lost.
    </Warning>
  </Accordion>

  <Accordion title="High battery usage">
    **Symptoms:** You notice High IQ appearing near the top of your battery usage list in **Settings > Battery**.

    **Solution:**

    <Steps>
      <Step title="Check screen time">
        Battery usage often correlates with how long the app was on screen. If you used High IQ for an hour, it is normal for it to use a proportional amount of battery.
      </Step>

      <Step title="Check background activity">
        Go to **Settings > General > Background App Refresh** and check if High IQ is enabled. For real-time sync to work efficiently, background refresh should be on, but you can disable it to save battery if you only need sync when the app is open.
      </Step>

      <Step title="Disable location services if unused">
        If you enabled location access for dispensary features but do not use them, go to **Settings > Privacy & Security > Location Services > High IQ** and set it to **Never**.
      </Step>
    </Steps>
  </Accordion>

  <Accordion title="Strain search is slow">
    **Symptoms:** Typing in the strain search bar has a long delay before results appear, or the search spinner runs for more than a few seconds.

    **Solution:**

    <Steps>
      <Step title="Check your connection">
        Strain search queries the API server. A slow or unstable connection will make search feel sluggish.
      </Step>

      <Step title="Be more specific">
        Searching for single letters or very common terms (like "og") returns many results and takes longer. Adding more characters narrows the search and speeds up results.
      </Step>

      <Step title="Wait for initial load">
        The first search after opening the app may be slower while the connection warms up. Subsequent searches are faster.
      </Step>
    </Steps>
  </Accordion>

  <Accordion title="Report generation takes too long">
    **Symptoms:** AI-generated reports appear stuck on "Generating..." or take more than 60 seconds to complete.

    **Solution:**

    <Steps>
      <Step title="Keep the app in the foreground">
        Report generation uses real-time streaming (Server-Sent Events). If you switch to another app while a report is generating, the stream may pause. Keep High IQ open until the report completes.
      </Step>

      <Step title="Check your connection">
        Streaming reports require a stable connection. If you are on a flaky Wi-Fi network, try switching to cellular data.
      </Step>

      <Step title="Retry if stuck">
        If a report has been stuck for more than 2 minutes, go back and regenerate it. Occasional server timeouts can cause a stream to stall.
      </Step>
    </Steps>

    <Tip>
      Reports are generated section by section with a visible progress indicator. It is normal for some sections (especially the AI analysis sections) to take 10-20 seconds each.
    </Tip>
  </Accordion>

  <Accordion title="App uses a lot of storage space">
    **Symptoms:** High IQ appears to use more storage than expected in **Settings > General > iPhone Storage**.

    **Solution:**

    <Steps>
      <Step title="Check cached images">
        High IQ caches strain images locally for faster loading. This cache grows as you browse more strains. Reinstalling the app clears this cache.
      </Step>

      <Step title="Reinstall to reset cache">
        If the app is using an unreasonable amount of storage (500 MB+), delete and reinstall it. Your data is stored in the cloud, so nothing will be lost. The cache will rebuild gradually as you use the app.
      </Step>
    </Steps>
