Uchinoko Diary is a memory app that lets you gently save everyday moments with your pet using photos and short notes. Once a day, up to one photo. Even without writing, you can casually record memories with just a photo or a stamp. You can look back on memories by date, and each month, choose one photo per week to create a special album page for that month. The more you keep writing, the more rewards you unlock, such as backgrounds, frames, and title decorations, so you can enjoy customizing your albums in your own style.

Verdict
The clearest difference is in-app purchases: Pet at none against Uchinoko Diary's 1. Pet also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.0). Uchinoko Diary's advantage is update cadence (every 3 days vs every 5 weeks). On price and device support there is nothing between them.
