Apps & Privacy
Do any of these apps require creating an account?

No. Every current DevByOne app (Slyp, Zen Loyalty Cards, Mnemo ToDo, Lucid RSS Reader, Kronologix, Cartfolio, RX Reminder, ClipVault, Sentinel, and Noor) works without signing up for an account.

Is there a private alternative to cloud-based receipt scanning apps?

Slyp scans and categorizes receipts with AI that runs entirely on your iPhone. Nothing is uploaded to a server. Get it at slyp.devbyone.com.

What's a to-do app that doesn't sync my tasks to a company's servers?

Mnemo ToDo is a private, distraction-free task manager with a quadrant priority system, calendar view, habits, and achievements. Any sync is via your own iCloud, not a DevByOne server.

Is there an offline employee time-tracking app for small teams?

Kronologix tracks clock-ins and generates real-time dashboards and reports fully offline, with no internet connection or account required.

What's a private RSS reader that summarizes articles with AI?

Lucid RSS Reader delivers your feeds distraction-free with instant on-device AI summaries, and works fully offline.

Is there a shopping list app that doesn't track my purchases?

Cartfolio keeps shopping lists, receipt tracking, and spend management private and local, with no account required.

What's a medication reminder app I can share with family without a cloud account?

RX Reminder offers flexible schedules, Care Circle sharing, and smart refill alerts: private, with no accounts.

How do I stop apps from silently using my Mac's camera or microphone?

Sentinel intercepts camera, mic, USB, and Bluetooth access on macOS with real-time blocking, Apple Watch approvals, and Touch ID.

Is there a Mac clipboard manager that keeps everything local?

ClipVault automatically saves and organizes everything you copy (text, images, and files) with instant, private, on-device search.

Is there a loyalty card app that doesn't sell my shopping data?

Zen Loyalty Cards digitizes every loyalty card with fast scanning, Apple Wallet integration, and iCloud sync: no third-party data sharing.

Is there a good Stocard alternative now that it's become Klarna?

Yes. Zen Loyalty Cards scans and stores loyalty cards with native Apple Wallet integration and private iCloud sync, a one-time $2.99 purchase with no account and no subscription.

Is there a Quran and prayer times app without ads or a subscription?

Noor is free, with no ads and no subscription: prayer times with adhan alerts, the full Quran with audio recitation, a Qibla compass, and Apple CarPlay support.
