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.
