Bytes vs ZeroTo

Bytes helps you keep track of your data usage. It shows you how much data you’ve used on both the mobile network (3G, 4G, LTE, etc.) and WiFi. Updated for iOS 10, the app features a beautiful minimalist design. With the ability to set data limits, monitor your daily data usage, send nightly notifications and more, Bytes helps you stay informed about your data usage. Bytes uses Background App Refresh to keep track of your data usage - it works best when left open in the background. Tab bar icons by Icons8 (http://www.icons8.com/). Note: Bytes does not take into account any carrier-specific promotions. Furthermore, your carrier and / or ISP reserves the final word regarding how much data your device consumed over any given period of time. Bytes works best on 64-bit devices.

Your iPhone is the timer. ZeroTo measures 0-60 mph, 0-100 km/h, the quarter mile and every gear shift, with no GPS box to buy. HOW A PASS GOES Mount the phone, pick a class and tap Stage. The start tree lights as the GPS locks and the car settles. Launch when it's safe. Timing starts the moment the car moves and stops by itself, and short beeps call each step, so you never touch the phone on the move. For the full ritual, turn on the tree's ambers, which leave time to spool the turbo. WHY THE NUMBERS HOLD UP GPS updates about once a second, too slow to catch a launch. ZeroTo also reads the motion sensors 100 times a second. They catch the first inch of movement and fill the gaps, and GPS keeps the speed honest. Every pass gets a lamp: accurate, approximate or not accurate, with an error estimate, so a time on a downhill or with weak GPS never passes as a clean one. ON EVERY SLIP - 0-60 mph, 0-100 km/h, 1/8 and 1/4 mile with trap speed - Road slope from the barometer - Speed trace, pull and gear shifts: how long each shift took and what it cost - Your previous pass in the same car, side by side - A map of the pass and of every place you ran CLASSES Sprint 0-60 (0-100), Long 0-130 (0-200), Rolling 60-130 (100-200) and a Full pass that measures everything at once.
