Simple. is a period tracker that does exactly one thing — track periods.

One big heart on the home screen. Tap it once: today is a period day. Tap it again: never mind. The countdown to her next period is right at the top. That's the whole app, on purpose.

No accounts. No passwords. No data leaves the phone.


WHY IT EXISTS

Every other period app wants to track her mood, her sleep, her hydration, her workouts. They have charts, "wellness scores," fertility supplement ads, and subscription tiers. They ask her to set goals.

She doesn't want goals. She wants to know if today is a period day, and roughly when the next one is coming. That's the whole job.


HOW IT WORKS

Three screens. That's the whole app.

— Today —
One big heart. Tap once to mark a period day. Tap again to undo. The countdown to the next period sits right at the top. No streaks. No graphs. No moods.

— Calendar —
Past periods show as filled dots. The next predicted period appears automatically — dashed, so it's clear it's a guess. Tap any day to fix it. Every change asks for confirmation first.

— Reminders —
Set a gentle reminders once: how many days before/after, and what it should say. Plain English presets like "Start wearing a pad" or "Pack supplies" — or write your own. The phone buzzes even with the app closed.


PRIVACY BY DESIGN

• No account, no login, no email
• No cloud storage
• No analytics, no tracking SDKs
• No ads — ever
• All data stays on the device
• The app makes zero network requests


DESIGNED FOR ACCESSIBILITY

Simple. was built first for a young woman with special needs. The whole design reflects that:

• Large tap targets
• Plain language, minimal text
• One primary action per screen
• Undo on every change
• Confirmation before destructive actions
• Read-aloud option for screen text

These choices help everyone, not just users with special needs.


FOR CAREGIVERS

Setup takes about one minute, no account needed. Two questions: when did her last period start, and how long is her cycle. After that, hand her the phone — she just taps the heart on period days. Reminders are easy to configure with plain-English presets.


PRICING

Simple. costs a small amount. That's how the work gets paid for, so we never have to sell your data, run ads, or push features she doesn't need.
