i want a simple walking app that does one thing that no other step counter does -- announces how far i've gone. so, let's say, every 500 steps or so, i want it to interrupt whatever audio i have playing to say something like: "<chime> <quick pause> you have now traveled five hundred steps" ... "<chime> <quick pause> you have now traveled one thousand steps" on android you can supposedly just rely on the internal step counter mechanism of the hardware. i currently use this one: https://play.google.com/store/apps/details?id=pedometer.steptracker.calorieburner.stepcounter&hl=en_US&gl=US https://play.google.com/store/apps/details?id=pedometer.step... if you make it, i will be your first purchase of $5/yr. i'm serious. UI-wise it prob just needs to show the number of steps you've gone. psmithsf@gmail.com
