Tik8

The family

Three apps, one habit: write it down, get it done.

Tik8 is a family of small, single-purpose list apps. Each one does one job, and all three share the same promises: no account, built for one thumb, works offline. We created the brand, designed and built the apps, and run their store presence and website.

  Tik8: Shared Grocery List

  One grocery list the whole household edits at once — shared with a 6-character code, sorted by aisle, usable one-handed in the store.

  Tik8 Goals

  A yearly goal tracker with a “flag for today” — see at a glance whether you are ahead or behind, and the pace needed to catch up.

  Tik8 To-Do

  Lists first, plan when you are ready. Tasks collect in colored lists and get planned onto a day or a week in a few taps.

Brand identity

One mark, built to stretch across a family.

“Tik” is the checked box; “8” is a closed loop — together, continuous, shared. A leaf replaces the dot of the i as the only figurative element, and the 8 sits a tone lighter to carry the idea of togetherness.

The master brand runs on a single electric indigo. Each app then gets its own accent — fuchsia for Goals, volt for To-Do — while the wordmark, icon language and one-thumb interaction stay shared. A 43-page brand guide documents the system.

Tik8: Shared Grocery List

A grocery list the whole household writes together.

Designed for the moment it is actually used: standing in an aisle, one hand on the cart. Changes sync to everyone instantly, and people without the app can join from a link in the browser.

• Share with a 6-character code — no sign-up, email or password
• Real-time sync and push notifications when someone adds an item
• Items sort themselves by aisle, with a single-aisle filter
• Type “2 lb tomatoes” and the amount is parsed; add several items at once
• Works without signal and syncs when back online
• Tik8 Plus subscription for unlimited shared lists and household pairing

Tik8 Goals

A year, measured honestly.

Write a goal the way you would say it — “Read 24 books”, “Save $5,000” — and it becomes measurable. A pace bar with a marker for today shows whether you are ahead or behind, without streaks or guilt.

• Four goal types: add up, reach, routine, finish with steps
• One-tap logging, long-press for a past day, every entry undoable
• Milestones at 25/50/75% and a one-time completion celebration
• A weekly review and a “welcome back” card after time away
• Plan next year from December and carry goals over
• Shareable year and goal cards; data stays on the device

Tik8 To-Do

Lists first. A plan only when you want one.

To-Do deliberately looks different from its siblings — volt on graphite, light and dark themes — while keeping the family’s interaction model. Tasks live in undated lists and get pulled into a day or a week when you decide.

• Colored lists for work, home, that trip
• Natural-language input for day, time, length and list in 6 languages
• An optional timeline: add a time and the task joins your day
• Week view to decide what gets done, then fit it into days
• Swipe gestures, drag-and-drop reordering and undo
• No account, no ads — tasks stay on the phone

Engineering

One monorepo, three apps, zero drift.

All three apps ship from a single TypeScript monorepo on Expo and React Native. Shared packages hold the design tokens, components, list engine and translations, so a fix or a new pattern lands in every app at once.

• Local-first storage with SQLite in every app
• Supabase with row-level security and real-time sync for shared grocery lists
• RevenueCat subscriptions and consent-gated AdMob and Firebase Analytics
• Automated checks: no hard-coded design values, WCAG AA contrast, locale parity
• 6 languages per app, checked against the source locale on every build
• Separate brand accents per app from one token system

Store creatives & website

Screenshots rendered from the product itself.

Store screenshots for every app and language are rendered straight from the apps’ own tokens, strings and logic — so the App Store always matches the product. tik8.app introduces the family, routes visitors to the right store, and opens shared grocery lists in the browser.
