Starspark is a diary app built around local storage. It doesn't rely on the cloud — your data stays on your devices, yet syncs directly across your phone, tablet, and computer via LAN. Your memories always belong to you. A casual photo, a video clip, a few lines of text—every little moment in life is worth cherishing. [LAN Sync, No Cloud, No AI] Under the same local network, your iPhone, iPad, and Mac connect directly to each other — no servers in between, peer-to-peer encrypted. We don't upload your diary to the cloud, and we don't feed it to any AI. Your data stays yours. [Your Data, Only Yours] All records are stored locally on your device. You can export and backup your data anytime. Even if you stop using the app one day, your stories remain intact in standard file formats, never locked by any platform. [Record and Revisit] - Freeform Recording: Use photos, videos, audio, and text to capture every moment worth keeping. - Multi-level Tags: Organize memories your way—like "Travel / Graduation Trip / Sunrise by the Sea". - Multiple Views: Card, list, and calendar modes let you relive your journey from different perspectives. [How to Use It] - Record Yourself: Selfies and monologues to capture the marks time leaves on you. - Photo Diary: A photo is a diary entry — one glance takes you right back. - Voice Diary: Say a few words and record it. Your voice gets closer to the moment than text ever can. - Mood Tracking: Happy or down, writing it out is a way of sorting it out. - Place Collection: Snap a photo, location auto-saved. Restaurants you've loved, views you've found — tap to navigate back. - Travel Diary: Photos paired with notes give scenery a story. - Parenting & Growth: Record your child's growing moments, from their first cry to their first steps. - Memory Organizer: Multi-level tags, calendar, card, and list views to revisit from every angle. [Privacy and Security] - All content visible only to you. Data stored locally on your device. - Peer-to-peer encrypted LAN sync. No data passes through any server. - No ads, no selling user data, no account registration required. - One-time purchase, not a subscription. [About Payment] Basic recording features are permanently free. Cross-device LAN sync is a paid feature with a 7-day free trial. One-time purchase — no ongoing subscriptions. Record an ordinary life. Record your story. Let images hold time, and let records be the witness of a lifetime. Email: xmlysk@163.com

sCycle is a period tracker with a companion. Pick Mo the otter or Juno the fox, give them a name, and they keep you company through the month. Every day starts with where you are: your cycle day, your phase, and when your next period is due. Your companion adds a line that fits the day. Mo is warm and a little silly. Juno is practical and helps you plan. CHECK IN WITH A FEW TAPS Mood, flow, and how your body feels: cramps, tiredness, bloating, headache, tender breasts. Tap what applies and skip the rest. If your period started, say so and the calendar moves with you. YOUR WHOLE CYCLE ON ONE SCREEN The calendar shows your periods, the next one predicted, and your fertile window. Tap any day to add, move or remove a period start. A COMPANION THAT REMEMBERS Had cramps around this time last cycle? Your companion will mention it and suggest something that helps. When a new cycle starts, you get a short summary of the last one. WHAT EACH PHASE MEANS Tap your phase for a plain explanation of what's going on in your body and what tends to help. PRIVATE BY DEFAULT Your cycle stays on your phone. You don't need an account. There are no ads, and your data is never sold. If you want your log on a second device, sign in and turn on Sapplify Sync. It's free and stays off until you switch it on. You can export everything to CSV or delete it all, any time. ALSO - A daily check-in reminder at the time you pick - Light and dark mode - 23 languages FREE, WITH ONE OPTIONAL PURCHASE Tracking is free, with no subscription. Pro is a one-time purchase that unlocks every companion, so you can switch between Mo and Juno whenever you like. sCycle predicts from your own history. It is not medical advice and not a method of contraception.

Verdict
Starspark and sCycle are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
