All perfect designed clocks. Beautiful, simplify, it's about Clock! It will show your location, the current weather information and latest 4 days forecast etc. - Swiss Federal Railways Clock - Girl Clock ... Check it out, I believe you will love it. See what customers said: Best weather clock app in App Store Nice bold clean graphics looks great accurate an I check back with it through out the day love it --by Johnnyp3301 Best Clock App I Have Seen This app is fantastic and exactly what I was looking for for my work desktop. There is even a very nerdy clock face with alternative mathematical notations for the numbers on the face. The only thing it is missing is a digital face but at this point I don't even care. Looks great on my 6+ in landscape mode! --by graphitical It's about Time. This is a very attractive product. Uses little power, lot of different features enabling one to get just the look. It is well worth a look/see. --by cadcts

Verdict

The call

The clearest difference is rating: Atomic Clock PRO at 4.7 against Super Clock's 3.7. Atomic Clock PRO also leads on ratings volume (10K vs 34). Super Clock's advantage is update cadence (fortnightly vs every 3 months) and iOS requirement (12 vs 15.6). On price, review sentiment, ads and in-app purchases there is nothing between them.
