Decima
Read full descriptionHide full description
The application you have before you is but a small attempt at working with time. Since it's a precious commodity all we can do is spend it wisely. That's why I've decided to spend a bit of my time and create Decima (named after Roman Parca, the female personification of destiny) so that you don't have to ;) So what you can do with Decima? In the current version 1.1 (Joséphine) you can: • create multiple timers • set multiple alerts per timer to track time expenditure • use it on both: your iPhone and Apple Watch (iPhone application is necessary) • start/stop timers on demand from your iPhone/iPad or Apple Watch • organize your time in sets • see total/partial time spent for a particular timer • automatically synchronise data between your iPhone and your Apple Watch (timer started on your phone can be paused on your Apple Watch and vice-versa) Have fun.

Verdict
The clearest difference is in-app purchases: Custom Digital Clock at none against Decima's 1. Custom Digital Clock also leads on iOS requirement (15.1 vs 17.0). Decima's advantage is ads (none vs shown) and update cadence (every 2 months vs every 9 months). On price and device support there is nothing between them.
