  • This app hasn’t received enough ratings or reviews to display an overview.

Goals to aim for, and a home screen that's yours. This update makes Letrics more personal and smoother to use every day. • Goals: switch them on in Settings under "Goals" and give any tracker a daily or weekly target. Aim for at least or at most, for its entries and for each number or rating on its own, like "at least 2,000 ml a day" or "at most 3 coffees". Turn goals off at any time; your goals stay saved. • See your progress: a progress bar on the home screen shows how far you are today or this week. On the tracker's page, each goal is a ring. Tap it to see how often you reached it and your goal streaks. Show, hide or move the goals block from the customize menu like any other chart. • Days that stand out: the charts draw a goal line and mark the days you reached your target or went over your limit. • A gentle tap: logging an entry now ends in a light vibration, and reaching a goal in a soft double tap. Prefer it quiet? Turn off "Vibration" in Settings. • Home chart with its own settings: choose which trackers, charts, time range and bar style appear on your home screen, independently of the Compare screen. You can now also change the order of the charts right from the home chart. • Multiple choice: choice values now appear as a clear list, one option per row, and you can tick as many options as apply. One entry can record "Sun" and "Wind" together. • Decimal numbers: number values now accept decimals like 2.5 or 0.75, with either a point or a comma. • Better ratings: the rating slider is now fully visible all the way to both ends. • Faster date and time: when logging an entry, the calendar and time picker open with a single tap. • Smoother editing: the Edit Tracker screen now scrolls from anywhere, so all your customization options are easy to reach. • New steps in the welcome tour: "Make each tracker yours" shows how to customize every tracker, from its name and color to the values it records and the charts it shows, and "Aim for a goal" introduces goals. • Cleaner home screen: the search bar is now hidden by default. If you like it, turn it on in Settings under "Search on the home screen". Thanks for using Letrics!
