Buying guide

myFirst Fone S3 vs S3+ vs R2 vs S4

Your kid will get a smartphone eventually. This guide covers age fit, features, GPS accuracy, and school policy, so you can match the right watch to your kid's age and your parenting philosophy.

Some kids' watches update location every 15 minutes. Not in real time, every 15 minutes. For a six-year-old who never leaves the yard, that's fine. For a nine-year-old walking home from school? You're tracking where they were, not where they are.

Here's where the myFirst Fone Smartwatch draws the line: every watch in the lineup does real-time GPS. Not the cheapest one with an asterisk and the rest as upgrades — all four. They all block strangers, too. But they're not the same watch, and guiding you to the right one comes down to three questions.

A few terms used throughout this guide

Kids GPS smartwatch

Find your match at a glance

Start with your child's age

This one question eliminates more bad purchases than any spec sheet. Smartwatches are one piece of a much bigger age-matching decision — for the fuller picture across cameras, earbuds, and other kids' tech, see our guide to choosing age-appropriate tech gadgets.

Question 1

How old is your child? Age guides the first cut.

Here's the lineup mapped to the ages it fits.

How Class Mode guides what your kid can access, and when

Class Mode isn't a blanket lock. A parent sets it from the myFirst Circle app, tied to a schedule (school hours) or a location (a geofence around the school). During Class Mode, calls are limited to approved emergency contacts only, the camera and games are disabled, and notifications are muted — the watch still tracks location the entire time. Outside those hours or that geofence, full features return automatically. It's the mechanism that makes the "guide, don't restrict" idea concrete: the child isn't locked out permanently, just scoped to context.

All four models — S3 (ages 5–7), S3+ (ages 5–7), R2 (ages 8–10), and S4 (ages 10–12) — support Class Mode.

Question 2

What are you trying to do? Match the watch to the goal.

Two parents of kids the same age can walk in with different priorities and walk out with different right answers from the same brand.

Why the Fone R2 looks different: the round face

Look at the lineup side by side and one watch stands out. The myFirst Fone R2 is the only round-faced model in the myFirst Fone family — S3, S3+, and S4 all use square displays.

That's not just a design choice. For kids aged 8–10, how a watch feels starts to matter as much as what it does. A round face reads as a real watch, not a tracker. It's thinner at 0.54″, protected by Gorilla Glass, and the 1.3″ AMOLED delivers sharper text and richer color than the square screens on the younger models.

The round form factor also makes the R2 the natural bridge between the S3/S3+ tier and the flagship S4. If your kid is at the age where they want a watch that looks like the one you wear — but they're not ready for the bigger S4 — the R2 is the answer.

The bigger picture

The philosophy behind the hardware

The smartwatch you pick for your kid is a parenting decision wearing a tech costume. Some brands take the restriction approach: strip the camera, block everything, lock it down. That works for a little kid; for a big kid, restriction alone doesn't teach, it delays. Others pile on features — music, games — and treat the watch like a mini phone, which just means more distractions and more to manage.

myFirst Fone Kids Smartwatch picked a third lane: guide, don't just restrict or overload. Real-time GPS so you know where they are without hovering. Habit Trainer so they practice managing their own time. Class Mode so features scale to context. magiCode so you can reach them without pulling them into a screen. The watch isn't a leash or a toy. It's a learner's permit for digital independence — and this guide exists to help you find the model that guidance actually fits.
