Most days is enough. Not every day. Set a weekly goal like 4 out of 7 days. Hit it most days, rest when you need to. Your progress never resets to zero. mostly is enough. Other habit apps count consecutive days โ€” miss one and the 90-day count goes to zero. Research shows the all-or-nothing model creates anxiety and guilt, the opposite of what builds habits. mostly replaces counters with weekly targets. No punishment for being human. HOW IT WORKS โ€ข Set a weekly target from 1 to 7 days for each habit (4/7 by default) โ€ข Check in each day with a single tap โ€ข See "2 more to go" on the way and "Goal reached" when you arrive. Week over? "See you next week" โ€ข Each week is a fresh start. Last week was tough? Clean slate. ENCOURAGEMENT OVER PUNISHMENT โ€ข No counters. No resets. No shame. โ€ข Rest days are part of the plan, not something to feel bad about โ€ข Quiet encouragement when things get tough โ€ข Progress matters more than perfection โ€ข Great for ADHD, anxiety, or anyone who wants a gentler approach GREAT FOR ANY HABIT โ€ข Morning routine, sleep, water, healthier eating โ€ข Gym, running, yoga, walking โ€ข Meditation, reading, journaling, studying โ€ข Quitting smoking, skincare, language learning SIMPLE & PRIVATE โ€ข Clean interface, no gamification, no social features โ€ข Your data stays on your device, with optional iCloud sync โ€ข Export your data anytime as JSON Lally et al.
