Verdict

The call

The clearest difference is in-app purchases: inti light at none against i's 1. inti light also leads on ads (none vs shown) and iOS requirement (7.0 vs 13.6). i's advantage is review sentiment (43% vs 11%) and update cadence (every 9 days vs every 4 weeks). On price and device support there is nothing between them.
