Apps that encourage/gamify walking?

Recently got Walk Scape which is a rune scape inspired game, but you do things by walking and just reads from the google analytics on your walking distance, so no gps and doesn't care where you go, just that you walk. So like to mine something, you take 10 steps, and so on. Also really nice that if you complete your current task, your steps are stored. So you don't have to do things while on the walk, you pick stuff to do before you walk, and then check in after. Really enjoying it!

Also got an app called Macadam, which gives you prizes for walking. But the model is kinda annoying because you'll get 25 coins for walking 2,500 steps in a day, but then you'd get like 5k for doing surveys and 10k for "playing partner games". So it feels a bit just like a mist play clone with a pedometer.

I didn't like games like pokemon go because the best way to play was always just to drive to a good place and hang out there. Also it required you to stop while on your walk.

Curious if there are any other fun walking games!
