The day-time is an upper half and the night-time is a lower half. -> 12-hour clock. -> The smallest scale division is 10 minutes. - Three-stitch clock - > The second hand is a clock which gains smoothly. - You can change the position and size of the clock. - You can choose a camera image or a photo as the background of the clock. - Please write a favorite character in a dial and make it your clock. - If it puts sideways, a status bar will not be displayed. - When continuing displaying in "Auto sleep"-off, we recommend you to connect with a power supply.

Artcodes allow everyone to become a coder. By drawing visually beautiful images, you can link them to websites to showcase how interaction can become fun and beautiful. Design visually beautiful images and encode them, resulting in the same interactivity as that of the QR code but with a more visually engaging and playful experience. Images can be identical with unique codes or the opposite: visually unique with identical codes. This interplay offers a new opportunity for visual interaction within, product, packaging, service and interaction design.

Verdict
The clearest difference is ads: Artcodes at none against OneHandClock's shown. Artcodes also leads on update cadence (every 2 months vs every 26 months) and rating (5.0 vs 4.6). OneHandClock's advantage is ratings volume (5 vs 1). On price, in-app purchases and device support there is nothing between them.
