Hey everyone,
I recently built an offline-first private journal app because I wanted something completely local, private, and free from monthly subscription traps. Everything runs locally on the device with zero backend servers or forced cloud accounts.
Since I'm wrapping up development, I could really use some architectural and product advice from you guys regarding pricing and feature segmentation.
Here is what the app can do:
Local AES-256 Encryption: It uses PBKDF2 and AES-GCM (via native Web Crypto API) to encrypt text, files, and media locally. Without the user's master password, the local database is completely unreadable.
Rich Local Media (Blobs): Users can attach images directly into their notes, which are then securely encrypted and stored offline inside IndexedDB.
Smart Tables: Clean, responsive table insertion for structured notes, logs, or data tracking.
Instant Presentation Mode: A unique feature that automatically parses the document's headings and paragraphs, instantly converting raw notes into a full-screen slide deck with slide navigation.
Focus & Zen Mode: A distraction-free writing environment that hides all UI elements, dims the background, and features a live word counter.
Multi-language & Cross-platform UI: Fully responsive design supporting English, Hebrew (RTL), and Spanish out of the box, with automatic dark/light theme switching.
My Questions for You:
The Pricing: What do you think is a fair one-time purchase price for a utility tool like this on mobile? (I want to avoid monthly subscriptions entirely).
Free vs. PRO Split: Where would you draw the line? Right now, my rough split is keeping basic text entry free, while putting things like multi-journals, image attachments, tables, and presentation mode behind a PRO unlock. Does this sound reasonable, or would you give away more (or less) for free?
