Bad element of a great site

Chess 24 is a wonderful site with excellent tournament coverage and great training materials created by top GMs like Jan GUSTAFSON and PETER Svidler who work for them. But the play zone and the iPad app are DOGS and its really a shame. The iPad app hasnt had a meaningful update in ages.
You will lose games you have in fact won, the app will crash in the middle of a game, the responsiveness and feel are slow
and poor all around. Its a pity, their gms are strong but their coders are patzers!

great on the subway about chess24, v1.5.5
