What It Is

Life Calendar is a dynamic wallpaper generator that uses APIs to create time-progress wallpapers for the iPhone lock screen. It can visualize the days in a year, 12 months, 4 quarters, or the week-by-week progress from your birth date to age 90 in a grid-style wallpaper. Strictly speaking, it is not a typical AI application: the crawled text does not mention any AI model, generative AI, or intelligent analysis capabilities.

Core Features

The tool provides four API endpoints: /api/days for 365-day annual progress, /api/months for a 12-month grid, /api/quarters for quarterly progress, and /api/life for life progress by weeks. Parameters include image width and height, theme, date, birth date, and a public background image URL. Available themes include amber, midnight, retro, terminal, paper, duck, blueprint, sage, rose, random, and more. The page also provides instructions for configuring iOS Shortcuts, allowing users to automatically fetch the image every morning and set it as the lock screen wallpaper.

Pricing

The crawled text does not provide any information about pricing, subscriptions, free quotas, or API rate limits. The page shows Vercel API examples that can be accessed directly, so the current information suggests it is closer to a free and openly available tool, but its long-term availability or SLA cannot be confirmed.

Pros and Cons

Its strengths are that the feature set is highly focused, wallpapers can update automatically once configured, and it works well as a persistent lock-screen reminder of yearly progress and life progress. The API parameters are clear, making it easy for technical users to construct URLs directly. The downsides are that it requires manual Shortcuts setup, which may be a barrier for casual users; service stability, privacy policy, and usage limits are not explained; and its use cases are largely limited to time visualization on the iPhone lock screen.

Who It’s For

It is suitable for productivity-tool enthusiasts, users managing annual goals, people who like quantifying the passage of time, and individual users familiar with iOS Shortcuts. It is not suitable for users looking for AI productivity, text generation, image generation, or enterprise-grade automation capabilities.

Access in China

The main text does not provide information about access from mainland China. Since the API is deployed on Vercel, actual accessibility may depend on the network environment, but this cannot be concluded definitively, so it is marked as unknown.
