“Graduation Radar” What it does, live and free (no API keys, no wallet connection, zero risk to your funds): •Streams every new token via PumpPortal’s free WebSocket and tracks trades in real time •Scores each token 0–100: curve progress, buy pressure (3 min), unique wallets, age (filters bundled fake pumps), net SOL velocity, minus a penalty if the dev wallet sells •Alerts with sound + optional push notifications when a token crosses your threshold in the graduation runway, plus a separate alert when tokens actually graduate •Built-in paper trading — one-tap hypothetical buys, live P&L, win rate, and average return that persist between sessions How to use it: open the page, let it run 5–10 minutes to populate, hit “Test alert” to check sound, and paper trade the signals for a week or two. If the stats panel shows a real edge after ~100 signals (needs roughly +15% average to clear fees and slippage), then consider tiny real position

Track commission payments and flag when payouts are short, missing, or clawed back.
u/JustinMoose · Reddit
I built an app that flags when commission earners get underpaid, unpaid, or clawed back I sell insurance for a living, and a while back I realized I had no real way to know whether the carriers actually paid me correctly. You bind a policy, and 30-60 days later some commission shows up on a statement, and you just kind of trust the number. Across hundreds of policies and a few carriers, that's impossible to track in your head. So I built PayoutVerify. You log what you sold and what you expe
