content: Though I liked the app but the ads are frustrating. After every study session completed there comes an ad that cant be avoided but watched. It breaks the rhythm of my concentration as I am bound to watch it and only then able cross the ad. These ads are undermining the very idea behind the app to help in concentration. Wanted to give it 5 stars but settling for 3. My request to developers to please find a suitable mid path so that both developers and users can be benefitted.
