Bars puts every limit you pay for on one screen: your AI plans, your API and cloud bills, your phone's data plan and your proxy's monthly bandwidth. One bar each, filling left to right, so the one closest to its limit is obvious at a glance. AI, CLOUD, CELLULAR AND PROXIES IN ONE PLACE Claude's five-hour session and its weeklies. Codex's windows. Notion AI. The Claude API, Vertex AI, AWS, Google Cloud and Cloudflare against a budget you set. Your carrier's cellular data plan. Proxy subscription links and VPS bandwidth. Add as many accounts as you have. A PACE MARK ON EVERY BAR A percentage tells you where you are. It does not tell you whether that is fine. Every bar carries a mark showing where you would be if you spent evenly across the window. A bar 78% full with three days left reads instantly as trouble; the same bar with three hours left reads as a job well paced. BUILT LIKE PART OF iOS A Live Activity counts down to the reset on the Lock Screen and in the Dynamic Island. Home Screen widgets come in small and medium, including one for this month's spend. Notifications arrive at the thresholds you choose, and when you start spending faster than the window allows. INSIGHTS AND RECEIPTS See what each day took from each limit and the pace of the window you are in, then print your month on a receipt you can share. YOUR CREDENTIALS STAY ON YOUR PHONE Bars signs you in the way the official tools do: the provider's own sign-in page, never a password box of ours. Tokens go into the iOS Keychain. There is no account to create, and your history syncs through your own private iCloud. FREE AND PRO Bars Free reads one account in full, with its pace mark and its notifications. Bars Pro reads every account and every limit, and adds the Live Activity, widgets, Insights and receipts. Pro is monthly, yearly with a free week to start, or once for life. Bars is an independent app and is not affiliated with, endorsed by or sponsored by Anthropic, OpenAI, Notion, Google, Amazon or Cloudflare. All product names and trademarks belong to their respective owners. Bars reads the same endpoints those services' own tools read, using credentials you provide, and any sample figures shown before you connect an account are clearly labelled as demo data.

Tachwire reads your car through a Bluetooth LE OBD adapter and puts what the dashboard keeps to itself — oil and gearbox temperatures, boost, gear, a hybrid's battery, on a BMW even oil pressure — on the car's screen, laid out the way you want. When something runs critically hot, it says so out loud. Deepest on BMW, which it asks through its own engine, gearbox and hybrid units. First support for many more makes, from Mercedes-Benz, Porsche and Ford to Toyota, Land Rover and RAM. Standard readings on any car with an OBD port. A SCREEN OF YOUR OWN IN THE CAR • Tiles of any size on a grid fitted to your car's display. • Pages for the road, the track and the warm-up, a button apart. • Arrange it on the phone, start from a layout in the Gallery, or edit on the car's screen while parked. • A Live Activity on the Lock Screen, in the Dynamic Island and, on iOS 26, in CarPlay. YOUR CAR AND YOUR DRIVES • Car: your car pictured in its factory colour; tank, battery, tyres and the last drive at a glance. • Drives: a diary by day — city, highway or track, with alerts, pulls and records. • A drive's page: the route, a verdict with its reason, every reading on one time line. • Route video: a 15–60 s flyover on an OpenStreetMap map, saved to Photos. • Logbook: records and trends against your car's own usual; ignition timing pull and power by rpm. • Power from the torque the engine reports, never estimated. 0–60 mph or 0–100 km/h, ¼ and ½ mile, timed from the car's speed — on a closed track only. ROAD CAMERAS • Spoken alerts and a map window on the car's screen for speed and red-light cameras, section controls and low-emission zones in Spain, Portugal, Italy, the United Kingdom, Poland, Austria, Belgium, Bulgaria, Norway, Cyprus, Malaysia and Russia. France: danger zones and low-emission zones only, as French law allows. Silent where such alerts are banned. • Off until you turn it on. TRACKS • 535 tracks in 17 countries, or set your own start/finish line. • Laps by session and the gap to your best, on the car's screen too. Runs and laps only on a closed track. • Track guidance in CarPlay: on a circuit, the track map with the next turn, and your braking points once a lap is recorded. A Track map tile for any page. WHICH CARS • BMW, the deepest: G-series from 2018 and F-series, recognised from the VIN — oil temperature and pressure, gearbox temperature and gear, boost, torque and power, a plug-in hybrid's e-motor and battery, a diesel's DPF and AdBlue. • MINI (2014–2024) and the Toyota GR Supra are read the way a BMW is. • First support, readings vary by model: Mercedes-Benz, Porsche, Ford (F-150, Mustang, Ranger and more), Toyota and Lexus (Land Cruiser 300 among them), RAM, Dodge, Jeep, Chrysler, Land Rover, Jaguar, Audi, Volkswagen, SEAT, CUPRA, Mazda and Honda. Their own readings stay quiet, with no warnings, until a drive confirms them. Renault, Dacia and Alpine are recognised. • Any other car with an OBD port: revs, speed, coolant, intake, load, often oil temperature and boost. A tile stays empty rather than show a wrong number. Make by make: tachwire.app/cars. WHAT YOU NEED • A Bluetooth LE OBD adapter: OBDLink CX (the fastest), vLinker, UniCarScan, or an ELM327 BLE clone (slower). Classic Bluetooth and Wi-Fi adapters can't connect to an iPhone. • iOS 18.4 or later and CarPlay, wired or wireless: the app reads the car only while CarPlay is connected. • No car nearby? Choose "No car yet" on the first screen for a demo drive. READ-ONLY, PRIVATE Tachwire only reads live values: no fault codes, no coding, nothing changed in the car. No account, ads or tracking. Drives stay on the phone unless you turn sending on (encrypted, route removed; only laps on a track keep their positions). Crash reports turn off with one switch; usage data only if you agree. GPS runs only during a drive. Tachwire is independent and not affiliated with or endorsed by any carmaker. All trademarks belong to their owners.

Verdict
The clearest difference is in-app purchases: Tachwire at none against Bars's 4. Tachwire also leads on update cadence (every 3 days vs monthly) and iOS requirement (18.4 vs 26.0). On price, ads and device support there is nothing between them.
