What it does
Thermal Buddy is a personal gear logbook for hikers, backpackers and trail runners. After each outing, log what you wore and slept in, the conditions, and how you felt, from Too Cold to Just Right to Too Hot. Before your next trip, search your past logs by temperature and instantly see what worked and what didn't. No account required — your logs live on your device and sync privately via iCloud. Free for up to 8 logs; the yearly plan includes a 1-month free trial.

Just Log2025 · justlog.app · ▲359Hi HN, I built Just Log after getting frustrated with fitness apps that were too complex for basic workout tracking. Most apps have social feeds, complicated interfaces, and features I never used. Just Log focuses on the essentials: quick workout logging, habit formation, and progress tracking without the bloat.
