# Line vs Inkalendar

The clearest difference is review sentiment: Inkalendar at 100% against Line's 33%. Inkalendar also leads on update cadence (fortnightly vs every 4 months). Line's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (14.0 vs 16.6). On price, ads, in-app purchases and device support there is nothing between them.
