Interval Timer - Workout Log helps you build precise interval routines by letting you set preparation time, exercise time, sets, cycles and cool-downs for any session. The app is ideal for HIIT, circuit workouts, boxing rounds and other timed training segments and provides an easy way to create, save and switch timers on the fly while timers continue running in the background as you use other apps. One-handed editing, swipe navigation and a calendar history keep sessions organized and accessible.

Key Features

Interval Timer - Workout Log lets you create and save unlimited custom timers with adjustable prep, exercise, set, cycle and cool-down durations. A built-in calendar view helps you review past activity and track workout history. Timers sync from the list and save automatically for quick edits and reuse. Background running and multitasking keep timers active when the screen is locked or you switch apps. Swipe navigation, flexible order control and previous/next set controls make in-session adjustments fast. Custom alerts, light and dark themes and support for 15 languages let you personalize the experience.

Advantages

With Interval Timer - Workout Log you get fine-grained control over every interval stage, speeding setup and in-session changes through one-handed editing and quick rearrange or repeat controls. Background operation ensures timers keep running while you move between apps or lock the screen, and the multilingual interface plus configurable alerts improve accessibility for diverse users.

Disadvantages

The app focuses on timing and does not include guided workouts, exercise demonstrations or coaching content. Very complex or highly varied programs may require manual setup rather than automatic plan generation. The feature list does not explicitly reference integrations with external sensors or wearable devices.
