See the following general tips and in your case especially #2

1. Use different screens wisely
   Before starting to create another screen, first you should think about is it really necessary? See also Building apps with many screens and SteveJG's post about advantages/disadvantages, because in only one screen you also can use vertical arrangements to simulate different screens, just set the arrangements to visible = true/false as needed... See also Martyn_HK's example about how to use Tabs in App Inventor and another example from Cyd. 
   
   If you decided to use different screens, then you should switch them correctly, else you will run out of memory after a while...      
   The recommended method of switching screens in App Inventor
   
   
App Inventor works best if you use images whose size matches the size you want them to appear on your screen. If you import larger images into your app, your app may run out of system memory. Using Images with App Inventor


2. Avoid redundancy

   Probably it helps to read chapter 19 - 21 in Dave's book http://www.appinventor.org/book2 to get an idea how to do DRY programming with App Inventor - Don't repeat yourself 
   

3. See SteveJG's monster list of tips and tricks

5. Backup your project frequently

Hi

See my tips on images for App Inventor / Android. Remember that Smart Phones are small devices with small screens, so large images are always an issue.
