Comments on Encyclopedia Chess Informant 1 for Android

★★★★☆ Philip Reilly · Jun 15, 2021
Pretty good app with some challenging problems. Some combination motifs are repeated a bit too often especially in the earlier sections but the does not happen as you progress.
★★★★☆ Prashant Bhavsar · Dec 25, 2018
Excellent App for Tactical ability improvement
★★★★★ Stuepat AreMarried · Mar 28, 2020
The Chess Informants where famous back in the day costing hundreds for these huge 12x18 books with real small print. This app makes studying ie tactics is graet - some exercises are but based on real e.g. like Tal etc. Incredible!
★★★★★ Rodrigo Teixeira · Jan 22, 2019
Great app! Exactly the same exercises found in the book. Excellent to study everywhere. The only downside for me is the exercises' enumeration. It should be the same as seen in the book. It is useful when you want to verify the author's analysis of an exercise which normally is much deeper on the book than in the App.
★☆☆☆☆ Hasan Basheer · May 3, 2021
Not given me full version even after payment done.
