Overview: Spot o’clock is a unique clock designed to be read out of focus. A fantastic innovation for people with poor vision and struggle to read traditional clocks without their corrective lenses. The clock face features a unique design where colored spots are arranged around the analog clock face, allowing users to read the time by position rather than clarity. Description: - Similar to reading a pair of six-sided dice, where the patterns are recognized rather than counting. - The current hour is interpreted by the position of the white spot among the visible red cornerstone spots.   - Just ahead of the current hour white spot is the place holder open circle that over rides the red cornerstones at 2,5,8,11 o'clock. - The open circle is critical to the clock function. - The minute is interpreted by the traditional position of analog clock hands. - Individuals can read Spot o’clock at a distance typical of a bedside nightstand or greater. Results may vary per individual. - Spot o’clock can also be easily read by active users who are physically on the go when small numbers are difficult to read in motion. iOS features: - Optimized for iOS18 + features - Spot o’clock on iPhone overrides screen sleep function to remain on for extended periods such as all night bedside clock or desk clock. - Please keep your device connected to power supply when doing so. - Auto orientation in either landscape or portrait modes. - Red underline below the clock face allows the user to identify which end is down to assist with auto orientation. Free version: - Ad banner - Utilizing only the base face for those who prefer a simple, less distracting display. - Apple Watch companion is a practical solution for users who need a reliable time-telling app without the fuss of reading small numbers. In app purchase Available: Unlocks pro features for those who prefer a bit more precision for all devices: iPhone, iPad and Apple Watch. - Red second hand (pro version) - Discrete hour indices (pro version) Visit www.spotoclock.com Watch the demo and read more about the Spot o’clock.

Verdict

The call

The clearest difference is in-app purchases: C at none against Spot o'clock's 1. C also leads on ads (none vs shown). Spot o'clock's advantage is update cadence (every 5 weeks vs every 5 months). On price, device support and iOS requirement there is nothing between them.
