What Griddiaryapp does
Grid Diary (格志日记) is a cross-platform consumer journaling application operated by Xiamen Sumi Network Technology Co., Ltd., a privately held Chinese company headquartered in Xiamen, Fujian Province. The product serves individual consumers seeking structured self-reflection, habit tracking, and personal planning, and is built around a proprietary grid-based diary format combined with a curated prompts library and customizable templates (gratitude journal, goal tracker, weekly planner). It supports multiple discrete journals per user, a markdown editor with inline images and todos, tags and stickers for organization, dark mode, passcode and biometric lock, calendar integration, configurable reminders, and export to PDF, Markdown, and JPG. The application is distributed globally across iOS App Store, Mac App Store, Google Play, and HUAWEI AppGallery, with bilingual English and Chinese websites and localization tailored for the Chinese market.
The underlying technology stack is a mobile-first, cloud-synced journaling application with platform-native clients on iOS, macOS, and Android. Authentication is handled through Apple Sign-In, Google Sign-In, and WeChat Login; payment processing runs through Apple In-App Purchase, Google Play In-App Billing, Stripe, PayPal/Braintree, WeChat Pay, and Alipay. Supporting infrastructure includes Firebase (Crashlytics and Analytics), OneSignal for push notifications, and Intercom for in-app customer support, with an Evernote export integration for data portability. The company does not disclose AI/ML capabilities, patents, or research output.
The business model is freemium consumer subscription. The free tier exposes core journaling features; a premium membership (priced at $2.99 per month with a 3-day trial or $22.99 per year with a 14-day trial, approximately $1.92/month effective) unlocks cross-device sync, passcode lock, and additional color themes, with the subscription covering all user devices. Go-to-market is product-led and self-serve, relying on app store optimization, earned media coverage from English- and Chinese-language technology outlets, a press kit, and organic social channels (WeChat and Weibo). The company has 1-10 employees, no disclosed funding, no management team listing, and no enterprise or institutional customer relationships.
