Most substitutes miss 3 to 5 jobs every week not because they weren't available, but simply because they weren't watching Frontline at the right moment.
Three steps and Nemo handles the rest.
Securely link your Frontline account in under a minute. Your credentials are encrypted and used only to book jobs on your behalf.
Pick your preferred schools, mark the days you're unavailable, and choose whether to accept overnight postings. Nemo never books outside your rules.
Nemo books matching jobs the moment they appear and notifies you right away. Simply show up and earn.
Nemo works exactly the same way you do. It logs in, looks for jobs, and books them. The difference is it never stops, and you can watch every step.
Every job Nemo scans, attempts, and books is logged in your activity feed. You always know exactly what it's doing. Nothing happens behind your back.
Nothing happens without a trace.
Every booking comes with a 2-hour review window. Not happy with it? Cancel before the window closes and you won't be charged a thing.
You decide. Always.
Only pay when Nemo successfully books a job for you.
