The Clocks app transforms your phone, tablet, or mac into a beautiful clock display, perfect for any home office, bedroom, or studio. It's perfect as an alternative to Standby Mode with even more options: ◎ 28+ gorgeous and intentionally designed animated backgrounds ◎ 15+ variations of clocks you can pair in any combination ◎ Some font and font color options for more personalization ◎ Private, no ads. Designed to be simple and stunning. ◎ Pro Park includes a download for matching screen savers on MacOS so your display can match across your entire work setup. ◎ Three clocks and three backgrounds are usable for free! ◎ Best used on a MagSafe charger, but also works on phones without it. ◎ Shortcuts support to allow Clocks to open automatically when connected to a charger Does Clocks open automatically? Not by default, but within Settings there's a tutorial on how to set it up using Shortcuts. Does Clocks replace Standby mode? We think Clocks is better fitted for daytime use and the official Standby for night time. Will you release more packs in the future? Yes! I plan on designing more backgrounds and clocks in future updates, some which will be free some which will be paid (but affordable). Roadmap - Coming soon: - Timers - More font options and settings

Verdict
