Best Days Since Apps for iPhone in 2026: 7 Compared
Checked 20 October 2026. Every competitor detail below comes from that app's US App Store page and Apple's public lookup data, fetched that day. Left details come from the app itself.
A days since app answers one question at a glance: how long has it been? Since you quit smoking, since you last called your grandmother, since you changed the water filter. Some apps are built for quitting, some for logging chores you repeat, and some count up as a side feature of a countdown app. Here are seven worth comparing on iPhone.
Disclosure: we make Left, so we have put it first. Here is why, and when another app suits you better.
Quick verdict
- Best for days since on your Home Screen and Lock Screen, next to countdowns and habits: Left.
- Best dedicated quit tracker: Days Since: Quit Habit Tracker.
- Best for countdowns and days since in one list: DayCount.
- Best "when did I last do this?" log for recurring chores: Last Time Tracker.
- Best for history, stats and an Apple Watch app: Hindsight.
- Best with in-app unlocks instead of a subscription: Countdown Days Since & Until.
- Best if you mostly count down and sometimes count up: Countdown by Find Appiness.

1. Left: days since as streaks, on every widget surface
Left is a time awareness app for iPhone. A days since counter in Left is a streak, which lives in Since next to habits and Aims. Countdowns live in Ahead, and year and life progress in Time Left.
- How it works: create a streak and set Started on... to any past date and time. It counts up automatically. When you slip, or when you do the thing again, tap Restart and choose when it happened, anywhere between the start and now.
- History: each streak keeps its restarts, average streak, longest streak and reset history, so you can see whether the gaps are getting longer.
- Units: the Streak widget can show a streak in hours, days, weeks, months or years.
- Widgets: the Streak widget comes in small, medium and large, with an optional photo and the start date, and as a rectangular Lock Screen widget. The Streaks list widget shows 3 (medium) or 7 (large) on the Home Screen. The Streak widget also works in StandBy. The Streak and Streaks list widgets are free.
- Reminders: Get reminders and Get elapsed-time reminders on each streak.
- Left Premium extras: unlimited streaks, friends who can follow your streak for accountability, and Apple Health tracking that resets a streak when a period ends without meeting its goal.
Best for: people who want "days since" visible on the Home Screen or Lock Screen, and want it next to countdowns, habits and a sense of how much of the year is left.
Price: free to download. The free plan includes 2 streaks (plus 2 habits, 2 Aims and 2 countdowns), and the count includes every item you've ever created, so deleting one doesn't free a slot. Left Premium is a subscription or a lifetime purchase. Prices are shown in the app before you buy.
Pros: the Streak widget is free on the Home Screen, Lock Screen and in StandBy; restart history with average and longest streak; the Streak widget shows units from hours to years; countdowns, habits and goals in the same app.
Cons: only 2 free streaks, which is tight if you track many things; iPhone only, and it needs iOS 26 or later; no Apple Watch app; a streak is one running count, so it doesn't group chores by how overdue they are the way Last Time Tracker does.
2. Days Since: Quit Habit Tracker
By A Couple of Friends OOD. Its App Store page describes a counter per habit: you set the last time you did it and the app shows how long it has been. The listing is framed around quitting, with a quit-smoking example, and the latest release notes add a Home Screen widget for Goals.
Best for: quitting something and watching a clean count grow, in the most-rated dedicated days since app on the list.
Price: free to download. The in-app purchases include Count Up Club and Premium plans, billed monthly, yearly or once for lifetime access. The listing doesn't say what the free version includes.
Pros: 4.8 stars from 19,499 ratings; listed for Apple Watch, Apple silicon Macs and Vision Pro; its privacy label lists only usage and diagnostics data, not linked to you.
Cons: the listing doesn't state free limits; Lock Screen and StandBy widgets aren't mentioned; it's built around quitting, so it's less of a fit for logging chores.
3. DayCount
By Zaminiti Pty Ltd. Its App Store page describes event counters that track time before and after a date, so countdowns and days since sit in one list. It adds daily streaks with your longest run, categories, photos from your library or Unsplash, notes, repeating events and reminders before or after an event.
Best for: one app for counting both ways, with customizable widgets.
Price: free to download. DayCount Premium is an annual subscription with a 7-day free trial, or a lifetime purchase.
Pros: Home Screen and Lock Screen widgets with filters, fonts and textures; a daily summary notification; sync across iPhone, iPad and Mac; Face ID app lock; Siri and Shortcuts.
Cons: Apple Watch isn't in its compatibility list; its privacy label lists contact info and user content as data linked to you.
4. Last Time Tracker
By Sarun Wongpatcharapakorn. Its App Store page describes a one-tap log of the last time you did something, with a note or a chosen date. It groups events into Overdue, This Week and Later based on how often you actually do each one, and keeps every entry with the gap between them, your average and when the next is due.
Best for: recurring life admin: the dentist, cutting your hair, calling your parents, cleaning the gutters.
Price: $5.99 to download, with optional tip purchases. No subscription is listed.
Pros: a paid app with no subscription; privacy label says Data Not Collected; iCloud sync, CSV export, app lock, Siri and Shortcuts; a once-a-day Morning Digest notification.
Cons: no free version to try; widgets aren't mentioned in the listing; Apple Watch isn't in its compatibility list.
5. Hindsight
By Rogue Signal Inc. Its App Store page describes swiping to log an event, a timeline of every occurrence with notes, interval-based alerts, and statistics with a histogram view.
Best for: people who want history and stats for "how long has it been", and want to log from the wrist.
Price: free to download. The in-app purchases are optional monthly or yearly support and tips; the listing doesn't say they unlock features.
Pros: a full Apple Watch app; Home Screen and Lock Screen widgets; iCloud sync with no account; CSV export and import; Siri and Shortcuts.
Cons: it requires iOS 26 or later, like Left; fewer ratings (395) than the bigger apps here.
6. Countdown Days Since & Until
By Joseph Sferrazza. Its App Store page describes counting down to or up from a date in units from seconds to years, or in sleeps, with unlimited events, custom photos and icons, calendar import and custom alerts.
Best for: a free, mature app that counts both ways, syncs to Apple Watch, and lists no subscription.
Price: free to download. The in-app purchases are Unlock All, Remove Ads and effect packs, and the listing describes no subscription. The listing says widgets are ad-free with an in-app purchase.
Pros: Home Screen and Lock Screen widgets; Apple Watch support; sharing; recent updates add Siri controls and Spotlight search; supports iOS 15 or later.
Cons: the free version shows ads, including in widgets; the listing doesn't mention streak stats such as an average or longest run for a days since count.
7. Countdown by Find Appiness
By Find Appiness LLC. Its App Store page describes a countdown app with a count-up option on each countdown page, repeating events, tags, notes, a working-days-only count, iCloud sync and an Apple Watch glance.
Best for: people who mostly count down to events and occasionally want to count up from one.
Price: free to download. Widgets, formats, calendar auto-import and alarms are Premium; the in-app purchases are listed at $3.99 and $6.99.
Pros: by far the most ratings here (4.8 from 189,110); Home Screen, Lock Screen and StandBy widgets once unlocked; Apple Watch glance.
Cons: the free version shows ads and has no widgets (one in-app purchase unlocks widgets and removes ads); counting up is a secondary feature; its privacy label includes identifiers used to track you.
How we chose
- Search first: we searched the US App Store for "days since", "last time", "how long ago" and "count up" on 20 October 2026, and kept apps that count time since a past date as a core feature.
- Current and trusted: every app here was updated in 2026 and has at least a few hundred ratings. We left out apps with a handful of ratings, and apps that are mainly sobriety programs, which deserve their own comparison.
- Sources: each app's own App Store page and Apple's lookup data. We didn't use paid placements, and no developer reviewed this page.
- Fair cons: where a listing doesn't mention a feature we say "not stated" instead of assuming it's missing. Check the App Store page before you buy, because plans change.
Which one should you pick?
- You want the count on your Lock Screen and Home Screen for free, with countdowns and habits in the same app: Left.
- You're quitting one thing and want a dedicated quit counter: Days Since.
- You track dozens of recurring chores and want to know what's overdue: Last Time Tracker.
- You want stats and an Apple Watch app: Hindsight.
- You want countdowns and count-ups mixed in one list: DayCount or Countdown Days Since & Until.
For a quick answer without an app, the days since a date calculator and the hours since a date calculator work in your browser. If you're weighing a streak against a habit, the streaks vs habits guide explains the difference, and how to build a streak covers keeping one going.
