Stack

Read full description

Stack is a routine execution system for people who already know what they should be doing. You have a supplement stack. A skincare routine. A training programme. The problem isn't information, it's execution. Stack turns everything you already have into a clean daily checklist, then gets out of your way. IMPORT ANYTHING Paste your routine as raw text like notes, a WhatsApp message, a list, an AI summary. Stack reads it and builds your structured routine automatically. No templates. No manual entry. Just paste and go. TODAY VIEW Every block due today appears in one flat list, in order. Morning supplements. Evening skincare. Push day. You open the app, work through the list, and close it. That's the entire interaction. PROTOCOLS LIBRARY All your routines live in one place. Skincare, Supplements, Fitness, anything else. Each protocol shows how many steps are scheduled today and your current completion rate. Tap in to drill down to individual steps. HISTORY LOG Look back at any day. See exactly what you completed, what you skipped, and any notes you added. Useful for spotting patterns over time like realising you always miss Tuesday evening. INSIGHTS Weekly and monthly adherence charts with AI-generated analysis. Stack looks at your completion data across all protocols and surfaces specific, actionable observations, not generic encouragement. BUILT FOR PROTOCOL PEOPLE Stack is not a habit-building app. There are no streaks, no badges, no motivational quotes. It assumes you already have the discipline. It just removes the friction between knowing what to do and actually doing it. Works with any routine: supplements, skincare, training splits, mobility work, morning shakes, medication, meal prep. If it has steps, Stack can hold it. Dark and light mode. Notification reminders. Cloud sync across devices.

Never miss a set. Just lift. Nextset is the hands-free gym timer built for people who actually lift. Tap Start once at the beginning of your workout - then put your phone down. A clean chime plays every time it's your turn to lift. No fumbling, no forgotten timers, no tapping between sets. HOW IT WORKS Pick your set time and rest time. Nextset auto-cycles - lift, rest, chime, repeat - so you can keep your focus on the bar. THE LIVE ACTIVITY DOES EVERYTHING Drive the whole session from your lock screen. Pause, resume, skip to your next set, or end the workout without ever unlocking your phone. Glance at the Dynamic Island between sets - your countdown is always there. KEY FEATURES • One-tap start - enter your set and rest times, hit Start, pocket your phone • Live Activity + Dynamic Island - full controls on the lock screen • Auto-cycling work/rest - no more manual resets between sets • 8 chime sounds - Chirp, Ping, Bell, Triple, Whistle, Alarm, Gong, Pop • Repeat the cue 1–5Ɨ in a row so you never miss it in a loud gym • Plays over music - ducks Spotify or Apple Music briefly, then resumes • Whole-workout estimate - tell Nextset your set count, see your total time • Unlimited or targeted sets - go forever or cap at 8, 10, 12, 16, 20 sets • Dark, minimal design - built for low-light gyms and sweaty thumbs • Works in your pocket - no need to keep the app open MADE FOR LIFTERS Bench, squat, deadlift, overhead press, accessories - if you rest between sets, Nextset works. Heavy compounds, supersets, drop sets, AMRAPs, timed holds. Plate-loaded, cable, machine, barbell, dumbbell. Doesn't matter. NO ACCOUNTS. NO SUBSCRIPTIONS. NO ADS. NO PURCHASES. Nextset doesn't sell your data or push notifications. It runs locally on your device and only makes a sound when it's time to lift. TIPS • Try 45s set + 2m rest for compound lifts • Try 30s set + 60s rest for accessory work and supersets • Use Triple or Alarm in loud commercial gyms, Bell or Gong when you lift solo • Set a target number of sets to see exactly how long your workout will take Built for the rack. Made by a lifter.
