Frequently Asked Questions
Are these trackers safe to use in the ocean or pool?
All three models are designed to be water-resistant. The Garmin vivofit jr. 3 models are marketed as swim-friendly for kids, and the anyloop carries an IP68 rating suitable for splashes, showers and short swims. Rinse devices with fresh water after saltwater exposure and follow the manufacturer's care instructions to prolong life.
Do these trackers require daily charging?
Not necessarily. The Garmin vivofit jr. 3 uses a parent-replaceable coin-cell battery that can last up to about a year before replacement, so it avoids daily charging. The anyloop uses a rechargeable battery that typically lasts several days between charges and longer standby times depending on use.
Which model gives better swim metrics and tracking?
If you want simple, reliable swim-friendly wear for kids, the vivofit jr. 3 models focus on water durability and activity tracking rather than advanced swim metrics. The anyloop provides general activity and heart-rate data but may not deliver the detailed swim stroke analytics found on dedicated adult swim watches. Choose based on whether you need robust durability and battery life (Garmin) or more sensors at a budget price (anyloop).
