All functions except for the smart matching of dressing mirror clothing and the intelligent adaptation of dressing mirror clothing colors that require subscription (the first subscription is free for 30 days and can be cancelled at any time), all other functions (Professional clothing wardrobe management system, automatic calculation of clothing matching comfort, white noise sleep aid, photography fill light, etc.) can be used for free with full functionality. 1. AI Wardrobe After repeated careful creativity, in the previous version (which used the built-in professional clothing wardrobe management system to calculate the comfort level of different clothing combinations worn in different environments (temperature, humidity, wind speed, exercise form, exercise speed, indoor and outdoor differences, etc.), it was reconstructed into an external professional clothing wardrobe management system, and the analysis and calculation function was hidden behind the built-in clothing wardrobe management. In the process of user clothing management or matching, the calculation was automatically completed. Thoroughly simplifying the calculation process, the previously complex calculations have become super simple. And even if you don't care about calculations at all, you can still use it for free as a professional wardrobe manager. On this basis, OiK continues to be significantly optimized: the complex input parameters now only have one parameter, which most of the time does not need to be adjusted. Method: Based on analysis and calculation under various different situations, the scope is narrowed down to only calculate the comfort level of clothing matching in the office environment with air conditioning in summer and heating in winter. At this time, only the room temperature needs to be set as the only parameter, and all other input parameters are built-in as default values in the app, and the temperature is immediately saved after setting. As long as the temperature remains constant in the office environment, no parameters need to be set later. Completely simplified the analysis and calculation process. More intuitive demonstration: Watch a 1-minute demonstration operation video (which is built into the About OiK app) - very easy to use. The background music (including lyrics) of the demonstration video is specially created for this OiK app (example clothing images are generated by AI). 2. AI Mirror Based on professional wardrobe management, two powerful functions have been extended: outfit matching with a virtual dressing mirror and intelligent color adaptation for outfits with the virtual dressing mirror. More intuitive demonstration: Watch a 1-minute demonstration operation video (which is built into the About OiK app) - very easy to use. 3. UTIL Returning to the original intention of developing OiK: The app name OiK indicates that: it makes users feel comfortable (OK). Therefore, two very useful features have been carefully developed this time: 1. White noise (beneficial for sleep) 2. Photography fill light (5 types of lighting to help fill the light in low light environments), and it can also be used in outdoor popular music events such as holding up mobile phone lights for interactive occasions. Click on the screen to show/hide the control panel (5 types of lights). Continuously adding features that make people feel okay in the future. These features, except for the smart matching of outfits and colors by the dressing mirror which requires a subscription (the first subscription is free for 30 days and can be canceled at any time), can all be used with full functionality for free. 4. The image automatic art feature has been separated from OiK as a separate app: AutoFilter in the App Store Artistic beauty automatic filters with native cameras.

Verdict
The clearest difference is ads: OiK at none against Chisel's shown. Chisel's advantage is update cadence (every 2 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
