Consistency is the #1 predictor of actually reaching fluency. Pace plans your practice around your real calendar and rebuilds when life gets in the way.
Start for $130 minutes of focused work three times a week beats 5 minutes every day. Pace schedules the real sessions at times they'll actually happen.
Miss three days? Pace doesn't shame you, doesn't reset the streak. It shifts the plan so you still land at your target level by your target date.
Practice when you're wrecked from a bad day is worse than skipping. Pace sees your calendar and suggests times when you're likely to have energy for it.
Pace doesn't replace Duolingo, Pimsleur, italki, or your textbook. It makes sure the time to use them actually shows up in your week.
Pace generates the actual schedule from your calendar - this is just a shape.
