TB-303 note is an app for quickly jotting down and managing acid bass line synth sequences — TB-303, Behringer TD-3, Roland TB-03, and more. Perfect for those moments when: "I want to recreate this pattern on another machine, but checking all the original settings is a hassle..." "My hardware's memory is full, but I don't want to lose my favorite patterns." Patterns you save can be played back instantly. Turn the built-in synth knobs to dial in that signature squelch while you shape your line. Key Features: - A dedicated interface: A step sequencer screen that feels just like the real hardware. Note, Down/Up, Accent, and Slide — all editable on one screen. - Built-in preview playback: Audition your patterns instantly, even while editing, so you can hear it and tweak it on the fly. - TB-303-style tone knobs: CUTOFF / RESO / ENV / DECAY / ACCENT — dial in the feel before you commit it to hardware. - Dark mode support: Easy on the eyes during late-night studio sessions or on a dark club stage. - CSV export: Export your saved patterns as CSV for easy backup and management on your computer. Keep your acid basslines safe and ready, anytime, anywhere.

Cornerman is the anticipation engine for dads. It quietly reads your calendar, contacts and location — with zero input from you — and taps you on the shoulder before you drop something important. Like a cornerman in a boxer's corner, it watches the fight you can't watch yourself: the school event colliding with your late meeting, the birthday you haven't bought a gift for, the anniversary hiding behind a busy week. NO SETUP. NO LISTS. NO GUILT. Most reminder apps make you do the work. Cornerman does the opposite: you live your life, it connects the dots. WHAT IT DOES FOR YOU • Spots important dates and events before they sneak up on you • Cross-references your schedule, your people and where you are • Warns you early enough to actually act — not five minutes before • Learns the rhythm of your family life and gets sharper over time • Turns birthdays and anniversaries into a short prep plan you can send to Reminders • Stays silent when everything is under control BUILT FOR FATHERS Between work, kids and everything in between, dads carry an invisible mental load. Cornerman carries it with you, so being present doesn't depend on remembering everything yourself. Your privacy stays in your corner too: your data lives on your iPhone and, if you choose, in your own private iCloud. We run no servers and never see it.
