About this app

Pairlog is a logging app for couples and partners. The day you felt grateful. The evening you shared a meal. The promises you made together. Capture the small moments of everyday life and keep them as a shared record — just for the two of you. Sharing chores, how you communicate, syncing schedules, small acts of thoughtfulness. Pairlog helps you gently organize your life together, reducing the "I said it / I never heard that" mix-ups that can get in the way. We built Pairlog to be easy — not complicated settings or overly detailed tracking, but a quick log you can add the moment something comes to mind. Simple enough to keep up every day, natural enough to fit into your life together. What you can do: • Promise List — Keep track of things you've agreed on, so nothing gets forgotten. • Calendar — Look back and see what you did and when, together. • Gratitude Log — Record the moments you felt thankful for your partner, with a note to remember why. • Rewards — As you build up logs, you earn points toward rewards you choose together. The more you log, the more your shared time and memories take shape. Even on busy days, Pairlog helps you hold on to your feelings for each other — and the things that matter most to you both. A note from the developer: Pairlog isn't meant to score your relationship or turn it into a competition. It's a quiet place to keep your promises and gratitude, day by day. We care more about you using it at your own pace than using it perfectly.

Baseline captured. Growth appears after the crawler observes a changed rating count.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
