Foco - time and focus keeper

Foco is totally mute Pomodoro-like app that helps you to stay focused and get things done. It's made mute specially for those who would like to work in silence. Instead of the nasty alarm sounds the app just blinks the screen to signal you.
But it's not just a simple Pomodoro timer, Foco contains a bunch of useful features.
FEATURES
=========
TOTALLY MUTE WORK
Study in a library, work in open-space, or program at night. Foco will be useful is cases when you need to not disturb others, if there is a lot of noise around, or if you like to work in calm and silent.
MANUAL CONFIRMATION
You must tap a button to confirm timer's end and stop alarm. So no need to rush to stop your work when the timer goes off.
EXTRA TIME
Need just a few more minutes to finish your task? No problem! When the app starts blinking screen just tap at screen's center (where timer's placed) and get extra time. Same as standard iOS alarm clock does.
#TAGS
Select a tag for your tasks so you can see how much time you spend on each tag.
DAILY CHART
The app keeps your working time so you can see how long you have been focused.

HOW TO WORK WITH COMPLETELY MUTE APP?
=======================================
1. Start the timer and place your iPhone somewhere nearby (under your PC's monitor, near MacBook or papers). No need to put it right in front of you, it would be OK if you can barely see iPhone's screen with your peripheral vision.
2. When timer goes off the app starts blinking the screen to alarm you.
3. When you are ready to stop your work and relax a bit (or end a break and go back to work) just tap this-like (>>) button to stop alarm. Or take a few extra minutes if you really need to complete the task.
Note! If you lock the screen or close the app then timer will be stopped. The app can't blink the screen if it's not active! If you are planing to use it for hours, it would be nice to connect your iPhone to recharge.
