Penlock is a beautiful journaling app built on one principle: your words never leave your device. No cloud sync. No accounts. No servers. No subscriptions. Everything you write is stored locally on your iPhone — private by design, not as an afterthought. WRITE FREELY Create journal entries, attach photos, set your mood, and organize with custom colored tags. Whether it's a quick daily reflection or a detailed travel log, Penlock gives you everything you need — and nothing you don't. START FROM YOUR DAY On iPhone, Journaling Suggestions bring up moments from your day — photos, places, workouts and music — so you never face a blank page. You choose what to use; Penlock only sees what you pick. STAY PRIVATE Your journal is protected by Face ID or Touch ID. All data lives in Apple's secure local storage — never uploaded, never shared, never seen by anyone but you. BUILD A HABIT Track your writing streak and keep the momentum going. Add the streak widget to your Home Screen or Lock Screen. Use built-in writing starters — gratitude, daily reflection, goal setting, weekly review, travel log — or create your own custom prompts. DISCOVER YOUR PAST The Timeline view lets you navigate entries by date at a glance. Memories and the On This Day widget show what you wrote on this day in previous years. Full-text search puts every thought you've ever written at your fingertips. SHARE YOUR PROGRESS, NOT YOUR WORDS Celebrate a streak or your Year in Penlock with a shareable card. Cards show only your numbers — days, entries, words — never what you wrote. ONE PRICE. YOURS FOREVER. Penlock is a one-time purchase — no subscription, no recurring charges, all future updates included. Try it free with up to 10 entries, then unlock everything for life. FEATURES · Unlimited journal entries (after one-time unlock) · Custom tags with 10 color options · Photo attachments — up to 10 per entry · Mood tracking with 12 emoji moods · Writing starters and custom templates · Journaling Suggestions on iPhone · Writing streak tracker · Home Screen and Lock Screen widgets · On This Day memories · Shareable streak and Year in Penlock cards · Timeline calendar view · Full-text search · Markdown export · Face ID / Touch ID protection · Daily writing reminders · No cloud, no accounts · All future updates included PRIVACY Penlock does not collect any personal data. Your journal entries, photos, and preferences never leave your device. The only third-party services are RevenueCat for purchase validation and anonymous crash reports that help fix bugs — neither ever receives any of your journal content.

Verdict
The clearest difference is in-app purchases: Apollo ID at none against Penlock's 1. Apollo ID also leads on update cadence (fortnightly vs every 4 months). Penlock's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
