About

Loop

Read full description

You don’t need better motivation. You need fewer inputs. Loop is a 4-day reset to regain focus, reduce overstimulation, and train self-control through structure and not just willpower. Each day takes about 10 minutes. The commitment is short. The rules are clear. You pick one reset and follow a simple daily protocol. No habit tracking. No streaks. No endless optimization. Loop is private, quiet, and intentionally limited. There’s no feed. No social pressure. No performance layer. Instead of trying to improve everything at once, you finish one contained cycle. By day four, most users describe the same shift: their mind feels calmer, their focus lasts longer, and decisions stop feeling exhausting. Loop isn’t a lifestyle app. It’s something you complete, step away from, and return to when life gets noisy again. Do one cycle. Finish it. Repeat when needed. Notice what changes.

Sundry is the calm, private home for every number you keep. Weight, blood pressure, blood sugar, sleep, water, mood, heart rate, steps β€” or anything you can put a number on. Write it down in seconds and see the chart, the trend, and the stats right away. It has the speed of a notes app and the tidiness of a spreadsheet, without any of the setup. Made for anyone who already keeps a little list of numbers somewhere β€” on paper, in Notes, in a weight.xlsx β€” and just wants one calm place built for the job. WHY SUNDRY β€’ One home for all your numbers, instead of ten single-purpose apps. β€’ Fast to jot down β€” quick-add from the home screen, with your last value pre-filled. β€’ Clear at a glance β€” every tracker gets a chart, a trend, and stats, with nothing to configure. β€’ Private by design β€” your data stays on your device. No account, and nothing is uploaded to us. β€’ Yours to keep β€” a clean, tidy log of your own. WHAT YOU CAN DO β€’ Start in one tap with ready-made trackers: weight, BMI, body measurements, blood pressure, heart rate, blood sugar, sleep, water, mood, temperature, medication, and more. β€’ Or build your own β€” name it, pick an icon and color, and add exactly the fields you want. β€’ Track a few things at once in one entry β€” log systolic, diastolic and pulse together in a single blood-pressure reading. β€’ Fields for real life: numbers with your own precision, durations, yes/no, 1–5 ratings, and notes. β€’ Times fill in automatically, and you can always change them β€” log this morning's reading at lunch, or fill in older days. It never forces "now." β€’ Smart defaults bring back your last value, so a small change is a single tap. β€’ A full history for every tracker, grouped by day, week and month; swipe to edit or delete, with undo. β€’ Clean charts β€” line and bar, with week / month / 3-month / year / all ranges, a moving-average trend line, and more than one field on the same chart. β€’ Stats worked out for you: average, min, max, latest, change since last time, totals, and streaks. β€’ Insights that put two trackers on one chart, so you can see how they move together. β€’ Reminders that nudge you to log β€” set a daily, weekday or custom schedule for any tracker. β€’ Keep it tidy with categories, pin your favorites to the top, and search across names, notes and tags. β€’ Archive trackers you've finished with, without losing their data. β€’ Export any tracker β€” or your whole log β€” as a CSV table or a JSON backup, and share it wherever you like (Save to Files, email, a messenger) from the share sheet. β€’ Password-protect a backup if you want: it's encrypted on your device, and only your passphrase can open it. β€’ Restore from a backup with a preview first, then choose Merge (adds without making duplicates) or Replace. β€’ Lock the app with a PIN, and unlock with Face ID or Touch ID. β€’ Full dark mode and light mode, both designed as first-class themes. PRIVATE BY DESIGN Sundry is built to collect nothing. There is no sign-up and no account. Your entries stay on your device β€” we never see them. On the App Store privacy label, that is "Data Not Collected." Your data is never sold, never used for ads, and never shared. FREE β€” REALLY FREE Sundry is completely free. No subscriptions, no ads, no in-app purchases, nothing locked behind a paywall. The whole app is yours to use. CALM BY DESIGN Minimal, modern, and quiet. Your latest number is the hero on every screen; charts are thin and clutter-free; color is used as data, not decoration. Quick to open, easy for everyday logging. LANGUAGES & UNITS Sundry speaks several languages, and works in metric or imperial units, converted on the fly. A NOTE ON HEALTH Sundry is a personal tracking tool to help you record and understand your own numbers. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Any trends or statistics are for your information only β€” always talk to a qualified professional about health decisions.
