Read full descriptionHide full description
StickyFridge is a habit tracker built for two people. You keep the habit β water, the gym, meals, weight, studying, reading. One supporter can see that tracker, and nothing else you track. No feed, no followers, no strangers. One person, one habit, and a calendar that fills in a day at a time. HOW IT WORKS 1. Pick a habit from a template and name it whatever you call it. 2. Invite your supporter β by @handle or with a link you send them yourself. 3. Log the day: a number, a photo, a note, depending on the habit. WHAT YOUR SUPPORTER SEES β AND DOESN'T β’ Only the tracker you invited them to. None of your other trackers. β’ Your entries, the photos on them, and how consistent you've been lately. β’ They can react and leave comments. β’ They cannot add, edit or delete anything. The log stays yours. β’ Remove them whenever you want, and their access ends there. WHAT YOU GET β’ Ready-made templates: meals, studying, the gym, weight, water, reading β and more in the full picker. β’ Daily streaks, plus milestones: the first lands on your seventh logged day and comes with a card you can share. β’ StickyScore β one number for how on track your last seven days have been. A new tracker spends its first week building, so it never drags the number down. β’ Weekly and monthly calendars, so a good stretch looks like one. β’ Photo entries: log several meals in a day and pin one as the day's cover. β’ Charts that match the habit β weight over time, calories per week, weekly time. β’ Smart water reminders that nudge you when you're behind on the day's target. Off until you switch them on. CALORIE ESTIMATES FROM A MEAL PHOTO β’ Photograph what you ate and get a rough calorie range instead of counting by hand. β’ The photo goes to a third-party AI service only after you agree to it, and you set the portion yourself before anything is saved. It's an estimate, not a measurement. β’ Free accounts get 3 estimates in total β not 3 a month. Pro removes the limit. β’ Weekly trends: this week's calories, your weekly average, and the change from last week. StickyFridge isn't a calorie counter. It's the small daily promise, kept somewhere one person can see it. WHAT'S FREE 2 trackers, 1 supporter on each, the last 30 days of entries, and 3 AI calorie estimates. STICKYFRIDGE PRO β’ Unlimited trackers, and up to 3 active supporters on each one. β’ Build your own templates β your fields, your rhythm, your target. β’ Unlimited AI calorie estimates. β’ Your whole history: view and add entries for any date, not just the last 30 days. Pro is monthly or annual, with a 7-day free trial on the annual plan. It renews automatically until you cancel, and you can cancel anytime in Settings β Apple ID β Subscriptions.
