Thinline is a private Christian sin tracker. No account. What you write stays on this phone. You name what you track. Tap to acknowledge. Swipe when you held back. Optional short notes. Charts and a journal show what actually dominated — no streaks, no scores, no partner feed. Resist is one tap away when awareness isn’t enough: Reset, Move, and Story to interrupt an urge. Examination of Conscience is a session-only examen; answers are not saved. Optional App Lock uses Face ID or your device passcode. You can export a backup you control. Thinline requires paid access. The Founders Offer is selected whenever it is available; annual is the fallback. Eligible customers may receive a three-day monthly trial or seven-day annual trial. The Founders Offer is an immediate one-time lifetime purchase with no trial. Restore, export, and delete remain available without a subscription.
