What's a good Android app for watch faces that are a bit funky and colourful, but won't drain my battery while I'm backpacking through Southeast Asia?

Right, so I stumbled upon Neon Glow Watch Faces when I was looking for something a bit more 'me' than the standard watch faces. I wanted something colourful and fun, you know? And these neon designs are brilliant! They've got loads of different styles, and I can even tweak the colours to match my outfits – grand, isn't it? But the real test was whether it would kill my battery. I've been using it non-stop while island hopping in Thailand, and it hasn't been a problem at all. Plus, it doesn't eat up your roaming data, which is always a bonus when you're trying to avoid surprise bills. It's been an absolute godsend for adding a bit of personality without sacrificing battery life. Definitely recommend!
