LookOnce is a quick check tool for different moments in daily life.Your data is stored locally, giving you more peace of mind about privacy. It is not a to-do list, and it is not a complicated tracking app. It is designed for moments when you simply want to confirm something once before moving on — leaving home, traveling, commuting, starting work, preparing for sleep, running errands, or any small routine that you do not want to keep worrying about. You can create separate check scenes for different situations. Open the scene you need, go through the items, and finish the check in a simple, focused way. LookOnce 1.2 improves scene management with favorites and swipe-left deletion. It also adds sharing and export for completed check results, making it easier to save or use your confirmation record when needed. Check once, then let it go.

Verdict
The clearest difference is rating: LookOnce at 5.0 against Cleaner Cat's 4.7. Cleaner Cat's advantage is ratings volume (14 vs 1) and iOS requirement (15.6 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.
