Maryn is a fitness and lifestyle app built around guided challenges: structured training, meal plans that fit your goals, and a group that starts and finishes together. TRAIN WITH A PLAN Join a challenge and get a week-by-week training plan that unlocks as you go. Every session opens in a workout player that walks you through each block, set and exercise, with demo videos whenever you're unsure of a movement. Prefer your own schedule? Standalone training plans are there too โ€” start one any time and work through it at your own pace. TRACK EVERY SET Log reps, weight and RPE as you train. Your history stays with you, so you can see what you lifted last time and beat it. Personal records and training streaks are tracked automatically. EAT WITHOUT THE GUESSWORK Get a personalised meal plan built around your goals, with recipes for every meal and macros already worked out. Turn a week's plan into a shopping list grouped by category, so a grocery run takes minutes instead of an hour. SEE PROGRESS THAT ISN'T JUST THE SCALE Record body measurements and progress photos, and watch your workout stats and weekly consistency build over time. DO IT WITH OTHERS Every challenge has its own feed and group chat. Share a finished workout, ask a question, and see how everyone else is getting on.

About

Keepfasting

Features
Read full description

Keepfasting is a simple, intermittent fasting timer built around one idea: you should be able to glance at your Home Screen and instantly know whether you can eat. No accounts to create and no calorie counting. Just a clear countdown and a widget that tells you what you need to know at a glance. TWO WAYS TO TRACK Fixed Schedule Set the time your eating window opens once, and it repeats automatically every day. No daily interaction required. Log My Meals Tap "I Just Ate" or "Start Fasting" whenever it happens, and the app times your cycle from there. A WIDGET THAT'S ACTUALLY USEFUL Add Keepfasting to your Home Screen or Lock Screen and see your current phase in red for fasting or green for eating, with a live countdown that updates in real time. In Dynamic mode, a quick-log button on the widget lets you log a meal without even opening the app. A PROGRESS RING WORTH LOOKING AT Choose whether the ring fills up as your phase progresses or counts down as your deadline approaches, whichever mental model works best for you. A custom slider lets you fine-tune your plan with the red and green split as the control itself. REMINDERS, IF YOU WANT THEM Turn on optional local notifications for when your eating window opens and when it closes. They're off by default, so the app stays out of your way until you ask for it. ANY PLAN YOU LIKE Choose from quick presets like 16:8, 18:6, and 20:4, or fine-tune any custom schedule from 12:12 to 23:1 to match your routine. Your data stays on your device. There is no account, no login, and nothing to sync to a server. Download Keepfasting and start your next fast with a clear view of where you stand.
