For Tesla owners who can handle the truth

Your Tesla rounds up.
Way up.

The dash says 234 miles. The road says 158. TesBeHonest is the iPhone app that shows the number your car won't — live, honest, on every screen you own.

Your Tesla says 234 miles. The honest number is 158 miles.

Honest answer: 158 mi

76 miles just evaporated. Better here than on the highway.

Everywhere you glance

Honesty, delivered to
every screen you own

One honest number, computed from how your car actually drives — then pushed to your Home Screen, your Lock Screen, and your pocket before you ask.

Widgets with a spine

Home Screen and Lock Screen widgets put the honest number right next to Tesla’s — side by side, no flattery, glanceable before you commit to that third errand.

Notifications with receipts

Every drive start and finished charge, priced with your electricity rate. Real dollars, honest miles gained, kilowatt‑hours on the record — and trip history keeps every receipt.

Honest by design

Three promises,
zero asterisks

01

Never rosier than the dash

Our number can only be lower than Tesla’s — the app is built so it physically can’t flatter you. If anyone’s wrong, you arrive with miles to spare.

02

Math, not vibes

The honest number comes from how your car actually consumes energy on real drives — not a lab figure from a rolling road in perfect weather.

03

Your rate, real cost

Tell us what a kilowatt‑hour costs you, and a charge stops being “48 kWh” and starts being $6.72. Every trip, every charge, priced in your money.
