Curb vs Pacebit Internet Speed Limiter

Curb slows your iPhone or iPad's internet speed on-device — to save mobile data, beat doomscrolling, or test your apps on a bad connection. Everything runs locally. No accounts, no servers, no analytics. SAVE YOUR MOBILE DATA Streaming, autoplay and background sync quietly burn through a data plan. Put a ceiling on how fast data-hungry apps can pull, and a heavy video stream settles for a lighter quality on its own. • Cap video and streaming bandwidth so you stay under your monthly data allowance • Throttle just social media and video on mobile data, while maps, messaging and banking stay full speed • Stretch a limited or pay-as-you-go plan further, and avoid bill shock when roaming abroad • Set a gentle limit once and forget it — no per-app meters to babysit FOCUS AND DIGITAL WELLBEING Speed is a habit. Make the feeds that pull you in feel slow, and the urge to scroll fades. • Slow down social media, video and streaming while keeping the rest of your connection usable • Choose what to throttle: Everything, Only these (focus mode — slow just a chosen list), or All except these (keep the essentials fast) • Toggle ready-made bundles for Social media, Video and streaming, and News, or add your own domains • Make endless scrolling tedious enough to put the phone down FOR DEVELOPERS AND QA Test how your app behaves on a bad connection without leaving your desk. Curb is an on-device alternative to a desktop network link conditioner, shaping real traffic on the device itself. • Simulate real networks with one tap: 2G EDGE, 3G, 4G LTE, DSL, Bad Wi-Fi and Satellite • Set custom download and upload bandwidth • Add latency, jitter and packet loss to reproduce flaky conditions • Adjust bandwidth live while the tunnel runs — no reconnect needed • Watch a real-time throughput chart with current rates plus session totals HOW IT WORKS Curb uses a local packet-tunnel built on Apple's Network Extension. Your traffic is shaped on the device and never leaves it for any server of ours. There is nothing to sign in to. PRIVATE BY DESIGN • 100% on-device — no Curb servers • No account, no sign-in, no tracking, no analytics • Nothing about your browsing is collected or shared EDITABLE PRESETS AND LIVE CONTROL Every preset is fully editable. Tune download and upload speed, latency, jitter and packet loss, then save your own. Switch between presets instantly, and nudge the limits while a session is live to find the exact feel you want. DESIGNED FOR iPHONE AND iPAD A clean, native, universal app with light and dark themes. Note: Curb configures a local VPN profile on your device to shape traffic. This VPN stays on-device and is never used to route your data through external servers.

Limit internet speed and track daily data usage while Pacebit is connected. Pacebit measures traffic that passes through its on-device connection control. See live transfer speeds, set a daily allowance, and choose the pace that suits your day. Switch between Normal and Save data, or set separate download and upload caps. Changes apply to the running connection without a new setup. EVERYDAY CONTROL • See live download and upload speeds, plus data used in the current session. • Set a personal daily allowance for traffic measured through Pacebit. • Optionally slow the connection after the allowance is reached, while keeping it online. Pause that slowdown for the rest of the day when needed. • Review seven days of measured totals, with missing periods left unestimated. • Choose reminders near your allowance or an alert for heavy use in a 15-minute period. • Start and stop from a Home Screen widget after the first setup; Control Center controls are available on iOS 18 or later. • Run a website check and share a report without browsing history or IP addresses. HOW IT WORKS Pacebit uses iOS VPN technology to forward eligible traffic locally through this iPhone. iOS asks to add a VPN configuration when you first start connection control. Pacebit does not change your public location or decrypt HTTPS content. An optional mobile fallback can use cellular data for IPv6 if Wi-Fi lacks it. Traffic that bypasses Pacebit is not measured or capped. Totals include network overhead and are not your carrier's billed usage or remaining balance. A speed cap can change how an app streams, but cannot guarantee a lower bill or less total data use. Pacebit does not show per-app or per-site usage. PRIVATE BY DESIGN No account is required. Settings and aggregate usage records stay on this iPhone. Pacebit does not keep a browsing log or send usage records to a company server. Website lookups normally use your current network's DNS servers; if none are available, the tunnel uses Cloudflare DNS.
