A to-do list that feels like a night drive: neon horizon, retro sun, synth blips. Free, with a one-time unlock for additional Turbo features. Turbo launch price: $4.99. On the Horizon is a to-do list with a point of view. Every task sits on a neon horizon — a retro sun, a perspective grid, stars that twinkle while you work — and the whole app is built to be fast to use one-handed. FAST, FOCUSED, OFFLINE • Add a task in two taps. Quick chips for Today, Tomorrow and Next Week. • Tasks sort themselves into Overdue, Today, Upcoming, Someday and Completed. • Three priority levels with colour bars you can read at a glance. • Notes, search, swipe to complete, undo after delete. • Due-time reminders — a local notification at the minute you choose, tap it to land on the task. • Everything stays on your phone. No account, no sync, no network requests of any kind. MADE TO LOOK GOOD • Orbitron display type, chrome headlines, a sun that breathes. • Haptics and optional synth blips for every action. • Full VoiceOver support, Dynamic Type, Reduce Motion, Increase Contrast. TURBO (one-time purchase, no subscription) • Theme packs: Midnight Drive, Laser Grid, Chrome and Daybreak — a sunrise palette for people who like it light. • Matching app icon for each theme. • CRT scanlines overlay. • Home Screen and Lock Screen widgets: today's count, what's next, one tap to add. • Recurring tasks — daily, weekly or monthly, the next one appears when you finish the last. • Every future Turbo feature, included. Free stays free. Turbo is a single $4.99 unlock, restored on any device with your Apple Account.
