Falmouth RNLI were called out on Sunday to rescue four children cut off by the tide at Stack Point, close to Swanpool Beach.
Both the all weather lifeboat and the inshore life boat, alongside th Falmouth cliff rescue team, raced to rescue the children, aged between 12 and 14-years-old.
A RNLI spokesman said: "The inshore lifeboat did a great job working in amongst the rocks in darkness to safely recover the kids.
"It was decided that it was unsafe to land at Swanpool due to the dumping beach waves, so they were transferred to the all weather lifeboat and landed back at station and handed over to the coastguard cliff team until collected by their parents."
The rescue has sparked a reminder, and an idea from the lifesavers at the RNLI.
With almost every child using a smart phone, their mothers and fathers are being asked to get them a tide 'app' for their phone if they spend time on or near the water.
Posting on the Falmouth RNLI Facebook page a spokesman said this simple piece of technology could "hopefully cut down on the type of jobs we did last night", adding if there was a big sea running last night it "could have been a different story".
