What's a grand Android app for whipping up a quick photo collage when I'm on the go, say, waiting for a train in Italy?

Honestly, Photo Collage Maker - FunPic has been an absolute godsend on my travels. I'm always snapping pics, and sometimes I just want to throw a few together to share with the family back home or on my blog. This app is perfect for that! It's so easy to use, even when I'm battling dodgy Wi-Fi in some random hostel. I especially love that it doesn't eat up your roaming data, which is a massive win. I used it loads when I was backpacking through Southeast Asia – works perfectly in rural Thailand where the internet's a bit patchy. You can quickly select your photos, choose from loads of layouts, and add some fun stickers or text. It's proper useful for making travel memories look even better without needing to be a tech whiz. Sorted!
