Verdict

The call

The clearest difference is in-app purchases: Spinder at none against Hindi Alphabet's 1. Spinder also leads on ads (none vs shown) and device support (3 vs 1). Hindi Alphabet's advantage is update cadence (every 2 months vs every 5 months). On price there is nothing between them.
