Cronjob script trouble launching application

Question

I started with cronjobs a while ago, but up until yesterday I've run into a problem I can't figure/find out.

@reboot me /etc/application/start-script.sh

I have Raspbian Jessie (minimal) installed on a Raspberry Pi Zero. One of the users has a cronjob command @reboot. When I check "sudo /etc/init.d/cron status", I can see the cronjob is picked up after a reboot and executed. The only thing is that any output is dropped, the "No MTA installed"-message, (care?).

#!/bin/bash
# My start script

logfile=/home/me/logfile.log

echo "Starting program..." >> $logfile
application
echo "Program started!" >> $logfile

As you can see, it should create a log file, and it does this after a reboot when the script is called as a cronjob. This script works perfectly fine when you manualy execute it, it writes the output to the logfile AND starts the program.

The problem is: the program is not launched when the .sh script is called as a cronjob.

Why is only the application not started when the script is executed???
