BasicPomo is a Pomodoro timer with nothing in the way. Pick a session, watch a piece of fruit count down, and get back to work. Focus for 25 minutes. Take a real break. Repeat. That is the whole method, and this app keeps it that way. No accounts, no dashboards to configure, no streak-shaming. WHAT YOU GET Three rhythms Classic 25/5, quick 20/5, or deep 30/10, with a longer break whenever you need one. Swipe the timer to change duration. Statistics and streaks See how many pomodoros you finished today, how your week is filling up, and how many days in a row you have kept it going. Sessions that finish while your phone is in your pocket still count. Ten fruit themes Tomato, blueberry, avocado, eggplant, carrot, elderberry, vanilla, white mulberry, banana and strawberry. Seasonal surprises turn up during the year. Accurate to the second The timer keeps wall-clock time, so it stays exact while you switch apps, lock your phone, or run in Low Power Mode. Notifications let you start your break without opening the app. Sound and feel Five completion sounds, a silent option, and haptics if you would rather be nudged than chimed at. Siri and Shortcuts Start or pause a session by voice, or drop BasicPomo into a shortcut alongside the rest of your focus routine. Built for everyone VoiceOver reads the countdown as one clear phrase, text scales with your system size, and Reduce Motion is respected throughout. Private by design No account, no ads, no analytics, no network. Your sessions never leave your device. Works on iPhone and iPad, in portrait and landscape. Focus, measured.
