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.

Time your car's 0-60 mph, 0-100 km/h and quarter mile with the iPhone you already have. No GPS box to buy. Mount the phone, stop, and wait for "Ready". Launch when it's safe. The timer starts and stops by itself, and short beeps tell you what's happening, so you never touch the phone while driving. Want the drag-strip feel? Turn on the start tree: staging lights, ambers and green, with time to spool the turbo first. HOW IT STAYS ACCURATE GPS reports speed about once a second, which is too slow to catch a launch. ZeroTo also reads the motion sensors 100 times a second. They pick up the moment the car starts to roll and fill the gaps between GPS readings. GPS, in turn, keeps the speed from drifting. EVERY RUN SHOWS - 0-60 mph, 0-100 km/h, 1/8 and 1/4 mile with trap speed - Road slope from the barometer: uphill, downhill or level - A quality grade, so you know which times to trust - Speed and acceleration charts - Gear shifts: how long each one took and what it cost you - A comparison with your previous run in the same car - A map of where you ran, and a map of all your runs SHARE WITH FRIENDS Turn a result into a card for Instagram Stories or any chat. APPLE WATCH Start, stop and follow the run from your wrist. FREE AND PRO Accuracy is the same for everyone. The free version times the classics above with no limit on runs. ZeroTo Pro is a one-time purchase, not a subscription, and adds: - 60-130 mph, 100-200 km/h, 0-200 km/h, 60 ft, 1/2 mile and rollout times - Every gear shift in detail, compared run to run - A garage with any number of cars and notes for each tune - Unlimited history and CSV export - Share cards without the ZeroTo mark PRIVACY No account, no ads, no tracking. Your runs stay on your iPhone. Use ZeroTo only on closed roads or tracks where it's legal, and follow traffic laws.

Verdict
The clearest difference is update cadence: ZeroTo at every 6 days against Bytes's every 2 months. Bytes's advantage is iOS requirement (8.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
