Mind Cup turns invisible stress into a dark liquid filling a cup, so you can finally see how full you are. Avoiding the "I didn't notice until I hit my limit" moment starts with knowing how full your cup is. Mind Cup lets you log the day's strain and recovery in about 30 seconds, and shows your stress level as a real-time 3D cup. ◆ Made for you if ・You only notice stress once it has already overflowed ・You're not sure what is actually weighing on you ・You want self-care to become a habit, but it never sticks ◆ Features ・Simple logging — just pick Small, Medium, or Large for stress and recovery ・Your level is shown as a 3D cup; tilt your phone and the liquid sways ・See which recovery methods actually work for you, drawn from your own records ・When you're close to overflowing, a gentle nudge toward breathing or recovery ・Home Screen and Lock Screen widgets to check your level anytime ・A daily reminder and a quiet Sunday-evening weekly review ◆ Premium (free for the first 10 days, then a monthly or yearly plan) ・This week's tips (all your tailored suggestions, unlocked) ・30-day long-term trends and cause analysis ・Unlimited history ◆ Privacy All records are stored only on your device. No account required, and the developer never collects your data. * This app is a self-observation aid and does not provide medical diagnosis or treatment.

About

Hydro Dots

Features
Read full description

Hydro Dots is a water tracker that draws your day as a rising water level, one dot at a time. Tap once to log a cup, a mug, or a bottle. The water climbs. That is the whole idea. WHAT IT DOES • One tap to log — your usual sizes sit on the first screen. Custom amounts and drink types are one tap further. • Not every drink counts the same — coffee, tea, juice and the rest are converted by their hydration index, so what you log is what your body keeps. • A goal that follows your day — body weight, temperature, humidity, UV and activity shape the target. It settles once, the first time you open the app each day, so it never moves under you. • Reminders that know where you stand — each one carries how much you have had and the pace that would get you there. • History and recap — a week of bars, a month of dots, a streak counter, and the month's total turned into things you can picture: bottles, kettles, sugar you avoided. • Widgets — log from the home screen or the lock screen without opening the app. A month of dots fits on the large one. • Shortcuts and Siri — log a drink or ask what you have had today, hands free. Every action is available to build your own routines. • Apple Health — records can be written to Health, and removing a record takes it back out. PRO A one-time purchase. No subscription. • No ads • Every theme — seven palettes, from cream LCD to OLED black • iCloud sync — records and drinks across your devices PRIVACY What you drink stays on your device. Your records are not sent anywhere unless you turn on iCloud sync, and then they go to your own iCloud, not to us.
