Hi Leeann,
There is a way to do it with only your cell phone, although it’s a bit clunky. I’m using iPhone 6. Other cell phones may vary.
1. Find an image of a trophy you want to use and save it to your photo files.
2. Open the trophy pic from your photo files.
3. Tap “Edit” in the upper right corner.
4. Tap the pencil point icon in the upper right corner.
5. Tap the + sign in the lower right corner
6. Tap “Add Text”. A box will appear with the word “Text” inside. Delete the word Text.
7. Drag the text box with your finger to where you want your engraving to appear.
8. At the bottom of the screen, choose your font by tapping Aa, font size (appears as 60), alignment (bars), and color (tap black circle and color options will appear).
9. If you need to make changes, tap the pencil point in upper right corner.
10. Tap Done when finished.
Here are a few quick examples.
