Most habit apps hand you a 40-item checklist and a streak that punishes you the moment you slip. 21/90 does the opposite. You pick ONE habit and that's the whole point. The idea is simple: it takes about 21 days to build a habit, and 90 to truly live it. 21/90 walks every one of those days with you. WHY ONE HABIT Focus beats volume. When you commit to a single thing walk, read, meditate, pray, drink more water, stay sober you actually do it. No dashboard to manage. No guilt. Just show up, tap once, and watch it become part of who you are. TWO ACTS, ONE JOURNEY Act 1 — Building it (days 1–21): the reps that wire the habit in. Act 2 — Living it (days 22–90): where the habit stops being a task and becomes your identity. The whole app visibly shifts when you cross day 21. A STREAK THAT'S KIND Miss a day? You don't start over here. Your progress is a record, not a rule and streak freezes let you protect a hard-won run. Consistency beats perfection. WHAT'S INSIDE A beautiful progress ring that fills as you show up Gentle daily reminders, tuned to your habit Streak, show-up rate, and clean insights A hand-picked quote for every one of the 90 days A day-90 keepsake card to share your story Home Screen & Lock Screen widgets Private by design your data is yours FREE, HONESTLY The Prayer habit is free forever. Every other habit comes with 21/90 Plus and a 7-day free trial, so you can try the full journey before you pay a cent. Pick one thing. Give it 90 days.

Cuke is a calm routine planner and visual timer for ADHD brains — with a small cucumber who never scolds. Pay once, keep it forever: no subscription, no streaks, no shame. Most habit apps punish a missed day: a streak breaks, a number turns red, a notification says "we miss you." Cuke doesn't keep score. Miss something and it quietly fades and waits. Come back after a hard week and today simply starts at zero. MEET CUKE A cucumber keeps you company on every screen. It holds on to the routine you're in, tugs the next one into your day, and lies down under the one that moved to later — cheerful every time. It has five faces and not one of them is disappointed. Finish a routine and it celebrates. Every active day adds a little brine to its jar, and the jar only ever fills. TIME YOU CAN FEEL • A shrinking ring for every step, not a number climbing — a time-blind brain can see ten minutes leaving. • A step-by-step routine player with gentle audible cues, so a locked phone still moves you forward. • Running late? A quiet "shifted +12 min" chip. Nothing turns red. • Focus blocks on your own terms: 10, 25 or 45 minutes, with a real break. ROUTINES THAT STICK • Start with one routine — morning, shutdown, meds & basics — or build your own in a minute. • Basics you can check off anytime: meds, water, food, with an optional time-sensitive reminder for the ones that matter. • Unmissable alarms, opt-in only: for medication, for the end of a focus block, or to wake straight into a routine. • Miss a routine and it moves to later. Skip a step and nothing is owed. ON YOUR LOCK SCREEN • Live Activity and Dynamic Island show the current step and the time left. • Home and Lock Screen widgets show what's next, quietly. • Siri and Shortcuts: "Start my routine in Cuke", "Log my meds in Cuke", "What's next in Cuke". SKILLS FOR STUCK MOMENTS • Box breathing in a jar: the brine rises as you breathe in, and an optional vibration follows your breath, so it works with your eyes closed. • Get unstuck: name the wall, slice the task into small rounds, start with one. • Ground yourself in 90 seconds. Nothing here is tracked or graded. A REVIEW THAT ONLY GROWS A calm weekly review of what actually happened — patterns in plain language, never grades, never leaderboards. An optional on-device pattern coach notices things like "mornings hold, evenings slip" and says so gently. It runs entirely on your phone. PRIVATE BY DESIGN No account. No ads. Cuke has no servers of its own — your data lives on your device and syncs only through your own private iCloud. Analytics are anonymous and content-masked; your routines and notes never leave as text. If you choose to download the optional on-device AI model, only the model comes down; nothing about you is ever sent to us. HONEST PRICING Your first routine is free, forever. Unlock unlimited routines with a single $24.99 purchase — one time, no subscription, nothing that renews. Cuke offers skills, not therapy. If things feel heavy, a professional is the right tool. Works on iPhone and iPad with iOS 26 or later.
