Nighp Software

Simple, thoughtfully designed apps for families and musicians

Nighp Software is an independent app studio. We build mobile apps that help families keep track of what matters most — from a newborn's feeding and sleep schedule to growth milestones and first words — along with practical tools for musicians and drivers. Our apps are designed around a simple idea: recording everyday life should take seconds, not minutes, and your data should always belong to you.

Millions of parents have used our apps to follow their baby's day, share records with caregivers and pediatricians, and look back on their child's earliest moments. Below you can learn more about each of our apps, read frequently asked questions, and review the privacy policy for every product we make.

First Year app icon

First Year

Record and share your baby's life story

First Year combines an activity logger with a scrapbook journal. Track feeding, diaper changes, sleep, growth, development milestones, and health issues, then add quick snapshots and journal entries to tell the story behind the numbers.

A quick-input mode records everyday activities with two taps and no typing, reports help you identify patterns and trends, and automatic synchronization lets family members and caregivers review and record activities from their own devices.

Growth+ app icon

Growth+

Baby growth charts made simple

Growth+ makes it easy to record your baby's height, weight, and head circumference and instantly see percentiles based on World Health Organization growth standards for children from birth to age five.

Review your child's history on intuitive growth charts, keep separate records for more than one child, print charts, and export your data in CSV or PDF format to share with relatives or your pediatrician.

Ovulation and Pregnancy Calendar app icon

Ovulation and Pregnancy Calendar

Plan ahead by knowing the future

OP Calendar predicts your fertility window by tracking your periods. The more cycles you record, the more accurate its predictions of future periods and fertile days become, helping you plan ahead with confidence.

If a baby is conceived, the app estimates your due date. An optional passcode keeps your records private.

Metronome Plus app icon

Metronome Plus

Your daily practice companion

Metronome Plus is a precise, customizable metronome for musicians of all ages and levels, built on accurate real-time audio technology. Customize rhythms by tempo, time signature, subdivision, polyrhythm, and accents, and choose from sixteen sounds and multiple visual themes.

Practice, training, and recording modes support daily practice and live performance, and a playlist manager saves your rhythms so your whole setlist is ready when you are.

Mileage Log app icon

Mileage Log

Mileage made easy

Mileage Log helps you record your trips and maintain accurate, organized mileage records for business expenses, tax deductions, and reimbursement claims.

Instead of scribbling odometer readings on paper, keep a clean digital log you can review at a glance whenever you need it.

About Nighp Software

Nighp Software has been crafting mobile apps since 2012. We are a small team, and we like it that way: every app we ship is something we use and care about ourselves. We believe parenting apps should save you time in the moments you have the least of it, and that tools for musicians should be accurate enough to trust on stage.

We also believe your records are yours. Our apps are built so that your data stays under your control, and each product's privacy policy explains exactly what is and is not collected.
