OneAlert

OneAlert is a lightweight and powerful reminder system with simple calendar.

Here is the three-step scenario of adding new reminder to OneAlert:

1. While working in any application press OneAlert hotkey (Win+Down by default);

2. Type in OneAlert parsing console: "Call Katrin in 15 min" and press Ctrl+Enter;

3. Press OneAlert hotkey again to return to application you worked with.

If you want to customize your reminder then just press Enter instead of Ctrl+Enter in step 2 and add additional parameters for your reminder (note, recurrence, different alert actions like send e-mail or run an application).
