HEPLANO Rhythm: The calm diary for your eating times

A calm diary for your eating times, for Android. With one tap you note whether it was a meal or a snack and see how much time has passed since your last entry. The app does not count calories, does not record weight and does not rate anything.

HEPLANO Rhythm is available on Google Play for Android.

The app is free to use and has no ads. Premium unlocks further features (see below) and is a subscription or a one-time purchase through Google Play. Before the purchase the app shows the price, term, renewal and cancellation; there is no trial that turns into a subscription on its own. Your data always stays visible, also without Premium.

Adults who want to note their eating times for themselves. It does not replace medical advice and is not a medical device. If you have diabetes, take medication, are pregnant, or have or have had an eating disorder, please talk to a professional before changing your eating habits.

No. It shows what you entered and gives no recommendations. It never asks you to wait longer or to go without food. Eating is always fine.

German, English and Polish. It follows the system language of your phone or the language you choose in the settings.

It shows the time since your last entry, for example “3 h 0 min”. If time information puts you under pressure, hide it in the settings; entries and overviews stay usable.

Yes. You choose the time when you add an entry and can change or delete entries later. For a meal you can enter how long it lasted; the break then counts from the end.

A moment in which you feel like eating something. You note it with a category: physical hunger, appetite, habit, boredom, stress or emotion, no hunger, or your own entry with your own name. An urge is not an entry and does not change the timer. No category is preselected.

Yes: a walk, strength training or something else, optionally with a duration. The app gives no recommendation and makes no statement about an effect.

Day, week, month and year. The day shows a timeline with entries and breaks, the week an overview, the month a calendar, the year an overview with one square per day. Month and year are part of Premium.

You mark a day yourself when you have entered everything for it. Only marked days go into the figures, so that incomplete days do not distort the values. The app does not ask you to do it.

A voluntary counter: one point per entry, urge or movement, at most 10 a day, plus 5 for a day marked as fully documented. More than 15 points a day are not possible. There are no streaks and no deductions. Points exist only for documenting, never for behaviour. You can hide them in the settings.

They are off until you turn them on. You choose the type (note a meal, daily review, close the day, review of a month or year, or your own reminder with its own name), the times and the rhythm: daily, on certain weekdays, every few days or monthly. You can pause them or set quiet hours. The texts are neutral and never contain data from your diary. Two simple daily reminders are free; further reminders, weekdays, several times, pausing, quiet hours and free reminders are part of Premium.

No. Android may delay reminders by up to about 15 minutes, especially while the screen is off. Open the app now and then so that reminders with “Every few days” and after pausing keep running.

Yes, a notification can appear on the lock screen. So do not write anything private in the name or text of your own reminder. The app never inserts data from your diary.

Only on your device, in an encrypted database. There is no account and no cloud. The app does not send your entries to a server.

Notifications (only when you turn on a reminder), biometrics (only for the app lock), start after restart (so that reminders keep running) and vibration. The app also contains permissions for internet and billing through Google Play, which are needed for buying Premium. The app only asks Google Play whether a purchase exists; your entries are not transmitted.

Yes. The app lock uses fingerprint, face or the PIN of your device. A screen protection prevents screenshots and the preview image in the app switcher.

With a backup: one file, encrypted with a password you choose. You store it yourself, for example in your cloud or on a computer. The password cannot be recovered. Without the password the file cannot be read.

Yes, as JSON or CSV. These files are not encrypted. You decide where to send them.

The last entry with its time and the running break. You place it on the home screen yourself. While it is there, this information is stored unencrypted in the private storage of the app. With the app lock on, the widget only shows “Open”. The widget is part of Premium.

In the settings under “Delete all data”. This removes the database, the key and the widget data from your device. It cannot be undone. A backup file you stored yourself remains until you delete it.
