This app serves as an alarm that provides notifications at dawn, sunrise, sunset, and dusk. If you wish to commence activities shortly after sunrise, this app is an excellent choice. It offers the capability to determine the timing of sunrise, sunset, dawn, and dusk for your current location and major cities instantly. Moreover, you can access this information even if you haven’t allowed local notifications. The app employs Japanese definitions for dawn and dusk, which were established by a samurai during the shogunate era, although they closely resemble civil twilight. Civil twilight commences and concludes when the sun’s geometric center is 6° below the horizon. In contrast, dawn starts and dusk ends when the sun’s geometric center is 7.3611° below the horizon. Enabling the civil twilight option will make the dawn and dusk correspond to civil dawn and civil dusk. ■ Liability Disclaimer ASTI disclaims all liability for any consequences arising from the use of the app. We accept no responsibility for any damages, injuries, or losses resulting from app usage.

“Is it time to replace this Mac?” UsedWell helps you look back on the things you use and decide for yourself whether to keep using them or move on. Add the purchase date, price, and your own usage goal to see how long you've had an item, how far you've progressed toward your goal, and what it costs per day. You can also keep notes on what you've actually noticed while using it. “Maybe I've used it long enough.” “The battery is getting worse, but everything else still works.” “Maybe I can keep it for another year.” UsedWell brings those pieces together so you can make the decision with your own context in front of you. Your time with it. Your goal for it. Set your own usage goal and see where you are today. UsedWell shows three simple states: Still want to use it, Start considering replacement, and Goal reached. At 90%, it's simply a point to start reflecting. 100% is not a replacement deadline. It means you've reached the usage goal you set for yourself. If you're still happy with the item, you can keep using it well beyond your goal. The frustrations. The reasons to keep it. Add dated Usage Notes whenever something stands out. For example: “Battery life has been getting worse.” “Still runs smoothly.” “Clearing some storage should keep it useful.” “Skipped this year's upgrade.” When you're considering a replacement, you can look back on more than numbers—you can also review how your experience with the item has changed. There's no need to log something every day. Add a note only when there's something worth remembering. Cost per day. One more perspective. UsedWell calculates your current cost per day from the purchase price and time used. You can also compare what the cost per day would look like at your usage goal and after one more year of use. The point isn't to “get your money's worth.” Cost per day is simply one more perspective when you're deciding whether to replace something or keep using it. Add a photo to make each item easier to recognize. You can add one optional photo to each item. Photos appear on Home, item details, and History. If you don't add a photo, UsedWell shows a category icon instead. Photos stay on your device. Choose between Warm and Forest. UsedWell includes two visual themes. Warm uses a soft Sand / Ivory palette. Forest uses a calm Cream / Deep Forest palette. Light and Dark appearance continue to follow your iPhone settings. Keep the record after you're done. When you actually stop using an item, mark it as replaced. The record stays in History so you can look back on your final time used, Usage Notes, final cost per day, and the period from purchase to completion. Key features • Add, edit, and delete items • Add one optional photo per item • Track time owned and your own usage goal • See progress toward your goal • Add dated Usage Notes • See current cost per day • Compare cost per day at your goal and after another year • Optional notifications at 90% and 100% of your goal • Mark items as replaced and keep a usage history • Choose between Warm and Forest themes • Light and Dark appearance Don't replace it on a whim.

Verdict

The call

Dawn Alarm's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.0). On price there is nothing between them.
