Getting started

Put it on your home screen

Open your Combo Lab link on your phone. iPhone (Safari): Share → Add to Home Screen. Android (Chrome): ⋮ → Add to Home screen.

Connect your Kalshi account

  1. On kalshi.com, open Account → Profile.
  2. In API Keys, tap Create New API Key. Kalshi shows a Key ID and downloads a .txt key file. Save the file; Kalshi can't show it again.
  3. In Combo Lab, go to Account → Connect Kalshi, paste the Key ID and pick the downloaded file.

Your key is saved only in your own Cloudflare account. Combo Lab still asks you to confirm every bet.

Sharp odds (optional, free)

Sign up free at the-odds-api.com. They email you a key. Paste it in Account → Sharp odds. The free plan covers normal use.

Paper mode

Flip to Paper at the top to practice with a $1,000 fake bank. Paper and live bets are tracked separately.

Using the app

Games

Pick a league, tap prices to add legs. "Fair %" is the sharp books' chance with their cut removed; green "value" means Kalshi is cheaper than fair.

Value picks

Lists every upcoming pick where Kalshi is at least 2 points under fair, strongest first. Tap Add to put it in your slip.

Compare

Set a budget and see how different ways of splitting your picks into combos pay out. Type your own % on any leg to use your read.

Goal Finder

Pick a league, time window, budget and target (2× up to 1000×). It searches every combination for the best chance to hit it. "Favorites first" prefers combos where the safe picks finish early so you might cash out before the long shots play.

Slip & placing

Get a real quote from Kalshi, then tap Confirm to place it. Nothing is ever placed without your tap.

Tracker

Every bet with live value, cash-out, results and P/L. Tap Assessment for a plain-English read of what's working.

Cash out

On open combos placed through the app, tap Get cash-out quote, then Cash out to sell. Cashed bets keep tracking so you can see what holding would have paid.

Edge

How often your picks win compared with the price you paid, by league, bet type and favorites vs underdogs.

Updates & troubleshooting
