The usage meter for AI subscriptions

£1.99 · one-time purchase, no subscription
What it does
Your limits, before they limit you.
Runlow reads the same usage data your AI tools see and turns it into meters you can actually glance at. No dashboards to log into, no maths. OpenRouter gets a meter of its own too: spend today, this week and this month, your credit balance, and a heads up before your key expires.
Every limit, one dashboard
Session, weekly and model-specific meters for all your providers, side by side. Tap any tile for a full-screen meter you can read from across the room.
See where your usage went
History charts show how each session and week actually played out, so you can pace the heavy work instead of hitting the wall at 4pm.
Pinned to your Lock Screen
A Live Activity keeps the meter on your Lock Screen and Dynamic Island while you work. No unlocking, no app-switching, just look.
Everywhere you work
From your wrist to your menu bar to your living room.
One purchase covers the lot. Paste a key once and your other devices sign in through your own iCloud Keychain, and your themes, meter names and order can follow too if you turn on settings sync.
iPhone & iPad
The full dashboard, widgets, and one-tap full-screen tiles.
Apple Watch
Your remaining runway on your wrist. A glance, not a check.
Mac
Lives in the menu bar. Your meters sit next to the clock, every limit one click away.
Apple Vision Pro
Your meters, floating in your space, in the same themes as your other devices.
Support development
Runlow costs £1.99. Everything is included.
No subscription, no ads, no analytics. Just one indie developer keeping the meters honest across five platforms. If Runlow has saved you from a surprise rate limit and you'd like to say thanks, there's a tip jar.
Tips are entirely optional. You can leave one inside the app, at the bottom of Settings on iPhone, iPad and Mac, where Apple handles the payment, or here through PayPal in your browser. Either way, they never unlock features. Everything in Runlow is included with your purchase.
