About this app
Sponsor Slot Ledger is a paid, local-first workspace for independent podcasters, small creator teams, and show producers who sell host-read sponsorships manually. Track sponsor campaigns, booked value, episode slots, read placement, copy approval, recording status, invoice notes, open sponsor tasks, and a copy-ready sponsor packet before recording day or billing handoff. The app is intentionally manual and private. It does not find sponsors, sell ads, process payments, generate invoices, provide legal or tax advice, insert ads into audio, record audio, transcribe audio, publish podcasts, connect to podcast hosts, connect to email, use AI, require an account, use ads, use analytics SDKs, track users, sync accounts, or upload entries to a developer server. One-time paid app. No subscription and no in-app purchases.
