1. Subscription Cost
Tractive's basic plan at $5/month is less than a quarter of Fi's pricing. Over a year, that's a $144-204 difference. Both require subscriptions for GPS tracking — there's no free option. Tractive also offers annual billing at $50/year ($4.17/mo) which is the best value. Fi's subscription is steep but includes more features like vet-recorded health insights.
2. Battery Life
This is Fi's biggest advantage. In default tracking mode, the Fi lasts 4-8 weeks between charges. Tractive needs charging every 2-5 days. If you hate charging devices, Fi is the clear winner. Tractive's battery drains faster because it updates location more frequently. In live tracking mode, both drain within hours.
3. Tracking Accuracy
Tractive updates location every 2-3 seconds in live mode with 3-5 meter accuracy. Fi updates every 1-5 minutes in standard mode with 5-10 meter accuracy. For finding a lost pet right now, Tractive's real-time tracking is significantly better. Fi prioritizes battery life over update frequency.
4. Cat Compatibility
Both are similar weight (30g vs 32g), but Tractive has a dedicated cat version with a smaller, cat-friendly design. Fi's collar is more dog-oriented though it does have a breakaway feature. Our test cat tolerated both after 2-3 days but seemed more comfortable with the Tractive's slimmer profile.
5. App & Features
Both apps offer virtual fences, activity monitoring, and location history. Tractive's app is slightly more polished with better territory mapping. Fi integrates with vet records and offers health insights. Both send reliable push notifications when your pet leaves a defined area.
Choose Tractive if: You want the best tracking accuracy, lowest subscription cost, or have a cat. It's the best all-around choice for most pet owners.
Choose Fi if: You hate charging devices, don't mind paying more, or want health insights. The battery life advantage is huge if you're the type who forgets to charge things.
Consider alternatives if: You need indoor tracking (Tabcat), don't want any subscription (AirTag), or have a very small cat (Tabcat at 5g).
Frequently Asked Questions
Is Fi or Tractive better for cats?
Tractive is slightly better for cats — it's 2g lighter (30g vs 32g) and has a dedicated cat version with a cat-friendly design. Both work for cats over 8 pounds. For very small cats, consider the Tabcat (5g) or AirTag (11g) instead.
Is Tractive's $5/month subscription worth it?
Yes — it's the cheapest real-time GPS pet tracker subscription available. At $5/month ($50/year on annual plan), it costs less than 20% of Fi's pricing while offering better real-time tracking accuracy. The value proposition is excellent.
Can Fi really last 2 months on a charge?
In optimal conditions (WiFi at home, limited GPS use), yes — Fi can last 6-8 weeks. In real-world use with daily GPS tracking, expect 3-4 weeks. Still far better than Tractive's 2-5 days. If charging is a pain point, Fi is worth the higher subscription.
Do both trackers work internationally?
Yes. Tractive works in 150+ countries with global cellular coverage included in the subscription. Fi primarily works in the US and is expanding internationally. If you travel with your pet outside the US, Tractive is the better choice.
Which tracker is better for finding a lost pet?
Tractive — its live mode updates every 2-3 seconds with 3-5 meter accuracy, making it much faster to locate a lost pet. Fi's standard mode updates every 1-5 minutes, which means your pet could be blocks away by the time you see the update.
