When contractions start, the last thing you need is a complicated app. BellyBean is the contraction timer that keeps it simple. Just tap to start, tap to stop. Duration, frequency, and intervals are tracked automatically so you can focus on what matters. IS IT TIME TO GO TO THE HOSPITAL? The 5-1-1 rule is the most common guideline: contractions 5 minutes apart, lasting 1 minute each, for at least 1 hour. BellyBean monitors your pattern in real time and lets you know when you've hit this milestone so you and your birth partner can make informed decisions together. FEATURES • One-Tap Timing — Start and stop with a single tap. No menus, no setup, no learning curve. • Automatic Calculations — Duration, frequency, and interval calculated instantly. • Contraction History — Every contraction logged with time and duration. • Visual Pattern View — Watch your contraction pattern develop over time with duration, interval, and intensity charts. • Smart 5-1-1 Alert — BellyBean tells you when your contractions match the hospital-ready pattern. • Intensity Tracking — Log each contraction as slight, mild, moderate, strong, or intense to see how labor progresses. • Dark Mode — Easy on the eyes during late-night timing sessions. • Works Offline — No internet required. Your data stays on your device. BUILT FOR THE MOMENT THAT MATTERS We know you're not downloading this app on a casual Tuesday. You're either preparing for labor or already in it. Every design decision in BellyBean was made with that reality in mind with large buttons, clear numbers, zero distractions. Your pregnancy journey is unique. BellyBean is here to give you one less thing to worry about. BellyBean offers a weekly subscription and a lifetime purchase.
