Your teenager just borrowed the car. A friend is driving it for the weekend. Now you'll know if something goes wrong.

Just let them know the car is monitored. --- OWNER DETECTION • Bluetooth Detection — Detects whether your phone is in the car, so alerts go out only when someone else is likely driving • No Manual Switching — Nothing to turn on or off • Owner-Aware Rules — Your own drives don't trigger alerts --- SAFETY ALERTS • Speeding Alerts — Notifications when your limits are exceeded • Possible Accident Alerts — Critical alert when unusually strong forces suggest a collision • Parked Impact Alerts — Get alerted if the car may have been hit while parked • Harsh Braking & Rapid Acceleration — Spot risky driving patterns • Critical Alert Override — Important alerts can bypass Do Not Disturb --- DRIVING HOURS & ZONES • Driving Hours — Get alerted when the car is driven outside the times you set • Choose the Days — Apply driving hours only on the days you pick • Geographic Zones — Get alerted when the car enters or leaves areas you define --- TRIP HISTORY • Drive Logs — Route, distance and duration for every trip • Live Location — See where your Tesla is on the map • Route Replay — View the path of any drive • Event Timeline — Driving events shown where they happened • Weekly, Monthly & Yearly Stats — See your driving over any period --- MULTIPLE VEHICLES • All Your Teslas in One App — Per-vehicle rules and alert sounds • Works With Model S, 3, X, Y and Cybertruck --- MADE FOR • New Drivers — Set limits while they learn • Family Cars — Know how a shared car is being driven • Lending Your Car — Peace of mind when someone borrows your Tesla • Older Drivers — Keep an eye on a parent's driving, with their knowledge --- WHY SENTRY DRIVER? • Official Tesla Fleet API — No extra hardware to install • Works With Your Existing Tesla — No Premium Connectivity required --- PRIVACY • Secure Tesla Sign-In — You sign in with Tesla directly; we never see your Tesla password • Only You See the Data — Trips and alerts are visible only to the account holder • Delete Anytime — Delete your account and all its data from the app • Tell Your Drivers — Anyone you let drive a monitored car must be told it is monitored (see our Terms) --- Start your 7-day free trial today.

Verdict
The clearest difference is in-app purchases: Discount Plus at none against Sentry Driver's 9. Discount Plus also leads on iOS requirement (12.0 vs 15.0). Sentry Driver's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 4 months). On price and device support there is nothing between them.
