TreeSpeed Guardian
Custom Speed Alerts & Trips
Free · In‑App Purchases
Choose an alert speed, start a trip, and let TreeTree help you stay aware with GPS speed, spoken warnings, Live Activities, trip insights, and optional routes.
TreeSpeed Guardian is a GPS speed companion built around a limit you choose. Select a travel mode and alert speed, then tap Start Guarding. Monitoring begins only for that trip. If your filtered GPS speed remains over the selected limit, the app can warn you with clear visuals, sound, vibration, speech, and notifications.

Privacy by design
GPS speed, trip summaries, and routes you choose to save stay on your device. They are not uploaded to a TreeSpeed Guardian server or provided to advertising services. You can delete individual trips, a selected day, or all local trip data.
Free and Pro
Speed alerts, background monitoring, travel modes, and basic statistics remain available for free with advertising. A rewarded ad can unlock one detailed trip report, and an optional ad grants 60 ad-free minutes. Monthly or yearly Pro removes all ads, unlocks detailed reports and routes, and adds complete TreeTree outfits across the app and Home Screen widget.
Subscriptions
TreeSpeed Guardian Pro is available as monthly and yearly auto-renewing subscriptions. Both plans unlock the same Pro features. Payment is charged to your Apple Account after confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel a subscription in your App Store account settings.
Safety notice
TreeSpeed Guardian is not a certified speedometer, navigation service, or source of posted legal speed limits. GPS readings may be delayed, inaccurate, or temporarily unavailable. Keep your attention on the road, follow posted signs and local laws, and never operate the app while moving.
