Cool Volume Free

Do you always happen to miss your calls because you don't hear the ringtone in noisy streets? Or maybe sometimes the ringtone is too loud for a quiet place such as your office.
This app solves this problem by adjusting sound level automatically! It understands how noisy your environment is, and SHAZAM! The volume is as loud as you want it to be.

I know this is amazing! You can try free version with some ads or buy full Ad-free version!

Current features:
✔ Adjusts Ringtone, voice call and SMS notification volume just when receiving a call or SMS
✔ So, does not drain phone battery at all
✔ Adjusts all volumes periodically
✔ Sets minimal and maximal volumes for quiet and busy places
✔ Sets sensitivity to noise means that with what ambient sound level set what volume.
✔ Shows changed volume notification or works completely silent

Future features:
- Auto increase ringtone when no one answers call
- Does not ring during sleep time
- and whatever you suggest!

I down loaded this great app it's louder and clear as a bell. I can hear my music and ring tones much clearer. I understand word by word now and ring by ring. I love it.
