You can choose which fields to show and arrange them in the order that works best for you. ■ TALK TO AI AND LET IT HELP YOU RECORD "I have a headache today and didn't sleep very well." Talk naturally with Seren, and AI can help organize what you said into your records. It can also help you look back on past records and notice patterns or changes that may be worth reviewing. Both text and voice input are supported. ■ REVIEW AND SUMMARIZE Look back on your daily records or create summaries for periods you want to review. --- Seren is free to use.

Verdict
The clearest difference is in-app purchases: Baletta at none against Seren's 1. Baletta also leads on iOS requirement (8.0 vs 15.0). Seren's advantage is update cadence (weekly vs every 76 months). On price, ads and device support there is nothing between them.
