About

CreatorBook

Read full description

Your creator business, in your pocket. CreatorBook is a manual-entry performance journal for content creators who post across multiple platforms. YouTube, TikTok, Instagram, X, LinkedIn, Pinterest, Threads, podcasts, newsletters, blogs - track them all in one place. No accounts, no API keys, no OAuth, no data uploads. You enter your numbers, the app shows you what is working. WHY MANUAL ENTRY Every platform has its own analytics API with its own quirks, rate limits, and OAuth requirements. Apps that depend on those APIs eventually break - data goes stale, integrations get revoked, monetization features stop working. CreatorBook never asks for platform access. You enter the numbers you see, when you see them, and the data stays on your device. WHAT YOU GET (FREE) - Track up to 3 platforms - Log followers, views, and revenue manually - Daily, weekly, and monthly entries - Weekly Check-in with an optional on-device reminder - Optional Face Lock using the device's biometric authentication - Basic line chart of growth over time - 30-day history view - Home screen widget (small + medium) - One creator profile - Full CSV export CREATORBOOK PRO - Unlimited platforms (12+ supported out of the box) - Post-level tracking with topic and format tags - Screenshot OCR - extract numbers from analytics screenshots, processed entirely on-device - Cross-platform comparison and pattern analysis (which content types drive the best results) - Revenue tracking with monthly breakdown - Effort efficiency analysis (views per hour spent) - Best posting time discovery - Goals with progress bars and deadline tracking - Multiple creator profiles (for agencies) PRIVACY FIRST CreatorBook does not collect, transmit, store, or share any of your data. The app has no servers. Screenshots used for OCR are processed on-device with Apple's Vision framework and never uploaded. PRO PURCHASE OPTIONS - Monthly: $3.99 / month (no free trial) - Annual: 7-day free trial, then $24.99 / year (save 48%) - Lifetime: $39.99 one-time purchase (no subscription or renewal) Payment is charged to your Apple ID at confirmation. Monthly and annual subscriptions auto-renew unless turned off at least 24 hours before period end. Manage subscriptions in Settings - Apple ID - Subscriptions. Lifetime is a one-time, non-consumable purchase and does not renew.
