A habit tracker and planner in one, with a habit pal to earn every day. Build your daily habits, work through your to-dos, and end each day with a bronze, silver or gold habit pal based on what you got done. Go solo or build streaks with friends. Your progress only ever moves forward. HABITS + PLANS, FINALLY TOGETHER Set recurring habits, keep a prioritized to-do list, and see everything for today in one view. Habits and to-dos both earn trophies, so every bit of progress counts. A HABIT PAL EVERY DAY Hit your goals to earn trophies, and watch your pal grow. At the end of the day, it joins your shelf as bronze, silver or gold, based on how much you did, not whether you did everything. There's a different pal each day, and no pal is ever taken away. SEE THE BIG PICTURE Look back at your week, your month or your whole year at a glance. Spot your streaks, trends and what's actually working. SEE HOW YOU COMPARE Find out how your sleep, steps, water, reading and more stack up against real population data. DO IT WITH FRIENDS Add friends with a code, see their habit pals and build shared streaks. When you both earn a pal on the same day, your streak grows. It's accountability without the pressure. WORKS WITH APPLE HEALTH Steps and other health habits fill in automatically, so you don't have to log them. Download Improve and start building better days.

Not everything is a daily habit. SinceWhen tells you how long it's been since the last haircut, oil change, vet visit, or dose, and when it's likely due next. One tap to log. No streaks. No guilt. No account. HOW IT WORKS • Name something you do now and then • Tap to log it, from the app, a widget, your Lock Screen, or Siri • SinceWhen learns your rhythm and shows what's due BUILT FOR REAL LIFE • Home & car: AC filters, oil changes, smoke detectors, deep cleans • Plants & pets: watering, fertilizing, flea treatments, vet visits • Health & self-care: as-needed medication, vitamins, skincare, dentist • Life admin: haircuts, calling family, reviewing subscriptions • ADHD-friendly: a zero-shame history for time blindness SMART, GENTLE PREDICTIONS SinceWhen studies the gaps between your logs and says things like "Usually every 6 weeks" and "Expected tomorrow". Pattern aware skips one-off long gaps, like a week away, and follows your real routine. Optional nudges arrive only when something is actually due, and you can log straight from the notification. MULTI-DAY EVENTS Tap once to start, tap again to end. Trips, sick days, and cycles are counted as Day 1, Day 2, and so on, with the full duration shaded on your charts. LOG IT IN SECONDS • Home Screen and Lock Screen widgets • Undo an accidental tap right where you made it • Siri and Shortcuts: "Hey Siri, log haircut" • Add a note, or backdate a log in a couple of taps EVERYTHING AT A GLANCE • Calendar with a ring on the next expected day • Interval and monthly charts • Categories with their own insights • Pause an event while you're away so predictions stay honest • Grid or list, pin what matters, dark mode, iPhone and iPad PRIVATE BY DESIGN No accounts, no ads, no analytics.

Verdict
The clearest difference is rating: Improve at 5.0 against SinceWhen's 4.4. Improve also leads on iOS requirement (15.1 vs 17.6). SinceWhen's advantage is ratings volume (14 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Improve sells 2 in-app purchases, starting at $4.99 per month and SinceWhen sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Improve holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: SinceWhen has 14 ratings behind it against 1, so its average is the more settled of the two.
Improve ships an update every 2 weeks, SinceWhen weekly. The most recent releases landed on October 30, 2026 and November 5, 2026 respectively.
