Why I built it
A routine should not need six places to track it.
Schedules, notes, screenshots, calculators and reminders can quickly turn one routine into several disconnected places to check. Peppy Diary was designed to bring the recurring recordkeeping into one organized product.
The experience focuses on what users need to do repeatedly: see what is due, log what happened, check vial status, rotate injection sites, review the calendar and follow progress over time.
Product thinking
Turn a complicated routine into a few clear actions.
See what matters now
Today’s Plan puts the next scheduled action first instead of making people interpret the full routine every time.
Make logging fast
Dose, draw amount and site details can be logged together, reducing the number of places a user has to update.
Keep inventory connected
Vial status and remaining supply stay connected to dose history, so routine tracking and inventory support each other.
Show the bigger picture
Calendar states and progress check-ins turn individual records into a clearer view of what happened over time.
Selected product flows
Designed around the repeatable moments.

Beyond the screens
The product needed a system around the interface too.
Guide a new user from an empty account to their first protocol without overwhelming them.
Telegram reminders connect routine tracking to the moments users actually need to remember.
Plan states, checkout flows and upgrade paths were designed as part of the product experience, not an afterthought.
The visual identity, product voice and social content system were developed alongside the app itself.
What this project demonstrates
Product thinking that connects the interface, the workflow and the brand.
