Here is one way :

(just call showFPS() in main.lua) and it will output the current fps to screen

[code]
function showFps()
local prevTime = 0
local curTime = 0
local dt = 0
local fps = 50
local mem = 0

local underlay = display.newRoundedRect(0, 0, 300, 20, 12)
underlay.x = 240
underlay.y = 11
underlay:setFillColor(0, 0, 0, 128)
local displayInfo = display.newText("FPS: " … fps … " - Memory: "… mem … “mb”, 120, 2, native.systemFontBold, 16)

local function updateText()
curTime = system.getTimer()
dt = curTime - prevTime
prevTime = curTime
fps = math.floor(1000 / dt)
mem = system.getInfo(“textureMemoryUsed”) / 1000000

–Limit fps range to avoid the “fake” reports
if fps > 60 then
fps = 60
end

displayInfo.text = "FPS: " … fps … " - Memory: "… string.sub(mem, 1, string.len(mem) - 4) … “mb”
underlay:toFront()
displayInfo:toFront()
end

Runtime:addEventListener(“enterFrame”, updateText)
