myFirst Fone S3 vs S3+ vs R2 vs S4
Your kid will get a smartphone eventually. This guide covers kids smartwatch age fit, features, price, GPS accuracy, and school policy, so you can match the right watch to your kid’s age, your parenting philosophy, and your budget.
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 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, and they all run on the same $12/month plan. 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: a wearable with cellular connectivity and real-time location tracking, built as a phone alternative for children too young for a full smartphone.
Class Mode: a scheduled or location-based restriction mode that limits calls, camera, and games during school hours while location tracking stays active.
magiCode: a scannable code on the watch face that lets a parent send a quick preset message or request without opening a full chat thread.
eSIM: a built-in digital SIM that doesn’t require a physical card swap, used for coverage across multiple countries.

This one question eliminates more bad purchases than any spec sheet. Find your kid’s age band below for the best-fit watch.
Question 1How old is your child? Age guides the first cut.
Here’s the lineup mapped to the ages it fits.
Younger kids · 5–7
If your kid just needs to reach you and you just need to reach them, start simple. Both pack real-time GPS, SOS, voice and video calls, and a 1.4″ touchscreen. S3 and S3+ are priced the same at $143.65, so the decision comes down to the small spec differences between them, check the comparison table below for the exact details, rather than budget. Keep it clean, feature overload is the enemy at this age.
The middle years · 8–10
When kids start caring how things look and feel. Thinner at 0.54″, a sharper 1.3″ AMOLED, a 5MP wide-angle camera, and Gorilla Glass. At $99.90, you get a screen and camera upgrade your kid will notice, a watch that feels like a real device, not a tracker.
The independence window · 10–12
The critical stretch: your kid wants autonomy, you want visibility. The biggest, brightest screen (1.65″ always-on AMOLED), best low-light camera, group chats to 8 contacts, plus Habit Trainer and magiCode. At $179.00, it's the flagship, and the bridge in the year or two before a phone.
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, $143.65), S3+ (ages 5–7, $143.65), R2 (ages 8–10, $99.90), and S4 (ages 10–12, $179.00) — support Class Mode.
Question 2What are you trying to do? Match the watch to the goal, not the price tag.
Two parents of kids the same age can walk in with different priorities and walk out with different right answers from the same brand.
“I just need to know where they are.”
S3 or S3+
You’re a GPS-first buyer. Real-time tracking, geo-fencing, SOS, and calling, done. You don’t need a 5MP camera or habit tools for this.
“I want them to build real independence.”
S4
Where the S4 earns its price. Habit Trainer works like this: you configure a short list of daily habits in myFirst Circle (make bed, read 20 minutes, brush teeth), the watch prompts your kid and they mark each one done themselves, and streaks build visibly on the watch face while you get a weekly summary in the app, not a real-time nag. There's no punishment mechanic; a missed day just resets the streak. It loosely borrows from
self-determination theory (autonomy, competence, belonging): your kid sets their own pace, builds competence through streaks, and stays connected to the family. A routine-builder, not a clinical tool, but the mechanism is concrete.
“I need a phone alternative, calls, video, messaging.”
R2 or S4
Both have 5MP cameras and support text, voice messages, photos, and group chat. R2 is lighter and cheaper at $99.90; S4 has the bigger screen and magiCode for $179.00. Younger (8–9), R2 is plenty. 10+ with group chats and habit tools, S4.
“We’re a two-household family, or we travel internationally.”
S4 or R2
Both run on eSIM with coverage across 120+ countries and support multi-guardian setup, each parent gets their own
myFirst Circle account with independent GPS access, alerts, and location history. For co-parenting, this is the feature that makes the watch work across two homes.
Question 3What does each watch actually cost to run?
Device price is the headline. The monthly plan, $12/month or $9.90/month billed annually, is the same across all four watches. So the real difference is upfront cost, a one-time decision.

The spread from cheapest to most expensive over a year is about $79.10 (R2 to S4). Not nothing, but not the kind of gap that should push you into a watch that doesn’t match your kid’s age and your actual needs.

A quick self-checkWhich one should you NOT buy?
✗
Don’t buy S4 if your kid is 5 or 6 and you just want calls and location.
S3 or S3+ does that for $35.35 less, and your kid won’t miss features they’re not ready for.
✗
Don’t buy S3 if your kid is 10 or 11 and a smartphone is coming soon.
Habit Trainer on S4 is the exact tool you want in that last year before a phone, and S3 doesn’t have it.
✗
Check your school’s device policy before buying any model.
All four have cameras. Most schools are fine with smartwatches in Class Mode; a few ban camera devices outright. Worth a two-minute check.
✗
Don’t buy S4 if you won’t spend 15 minutes on setup.
Habit Trainer and magiCode work, but only if you configure them. If setup feels like a chore, R2 or S3 will serve you better.
The bigger pictureThe 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.
In shortKey takeaways
01Age narrows the field; philosophy guides the pick. S3/S3+ (ages 5–7) for younger kids who need the basics. R2 (ages 8–10) for the middle years when screen and camera matter. S4 (ages 10–12) for the independence window when habit-building becomes essential — this is the guidance this whole page is built around.
02All four share the same foundation. Real-time GPS, SOS, approved-contact-only calling, Class Mode, and the myFirst Circle app. The differences are in the extras, which should match your kid’s stage, not just your budget.
03The monthly plan is the same across the board. $12/month, or $9.90 billed annually. So the $79.10 spread from R2 to S4 is the biggest real cost difference, and it’s a one-time decision.
04Co-parenting and international families have a clear path. S4 and R2 handle multi-guardian setups natively, with independent app accounts per parent and eSIM coverage across 120+ countries.
05The watch you’ll actually use beats the one with the most features. If you won’t set up Habit Trainer, don’t pay for it. Match the watch to the kid in front of you, not the one they’ll be in three years.
