A Pomodoro focus timer for study and work. Block selected apps, settle into cabin white noise and take a virtual flight across Earth. Flight Pomodoro turns completed focus sessions into boarding passes you can collect. Choose your destination, print a ticket and take off when you are ready. FIND A JOURNEY FOR YOUR TIME Pick your departure and destination or discover flights by focus time. Time-scaled mode keeps longer journeys longer. You can also match a session to the estimated flight duration provided for a route. BLOCK DISTRACTIONS, BUILD YOUR CABIN Choose apps to block while you study, work or read. Set the mood with cabin ambience and flight-inspired sounds. App blocking requires Screen Time permission. Haptics are available on supported devices. WATCH YOUR FOCUS CROSS THE EARTH Follow your aircraft over detailed continents, oceans, clouds, day and night. The camera tracks your flight, and you can rotate and zoom the globe to explore. PRINT YOUR BOARDING PASS Start with a paper-printing animation at the top of your device. On iPhones with Dynamic Island, the animation connects to the island. Printing a ticket and starting a flight are separate, so you decide when to take off. COLLECT THE TIME YOU COMPLETED Finished flights become boarding passes in your album. Complete a flight with app blocking maintained to receive your first passport stamp at that arrival airport. Turn the pages and zoom in to explore your collection. KEEP A JOURNAL OF YOUR FOCUS Review focus time, add journey notes and look back on your week. Export your records or save an encrypted backup file to restore later. ONE APP PURCHASE. EVERY FEATURE INCLUDED. No additional in-app purchases or subscriptions. Explore every available destination, keep adding album and passport pages, choose from three album designs, four cabin soundscapes and five app icons, and save your focus environments. Existing users also receive every feature when they update. Each page holds eight items, with new pages added as your collection grows. Flights and boarding passes are virtual experiences for focus. Flight Pomodoro does not issue real airline tickets, book flights or track live airline operations.

Verdict
The clearest difference is price: 작심삼일 at Free against Focus Timer's $2.99. 작심삼일 also leads on update cadence (every 2 days vs every 2 weeks) and iOS requirement (12.0 vs 18.0). Focus Timer's advantage is ads (none vs shown). On in-app purchases and device support there is nothing between them.
