The Best Apps for Tracking Days Since an Event (2026)
You changed the water filter three months ago. Or was it four? You last visited the dentist sometime in spring — you think. Your car is due for an oil change, but you can’t remember exactly when you last went.
Sound familiar? That’s exactly what a days since app is built for. These simple but powerful tools track how long it’s been since any recurring event — so you always know when it’s time again.
In this article, we’ll compare the best apps for tracking days since an event in 2026, so you can find the right one for your needs.
What Makes a Good Days Since App?
Before diving into the comparison, here’s what to look for:
- Cross-platform availability — Does it work on your phone, your partner’s phone, and the web?
- History with notes — Can you see not just how long it’s been, but what happened each time?
- Reminders — Will it remind you when it’s time to act again?
- Templates — Does it help you get started quickly with common use cases?
- Simplicity — Is it easy enough to actually use every day?
With that in mind, here are the top apps available right now.
1. SinceNow — Best Overall Days Since App
Platforms: iOS, Android, Web Price: Free (Premium subscription available)
SinceNow is the most complete days since counter app available in 2026 — and the only one that works across iOS, Android, and Web simultaneously.
You create a task, and SinceNow starts counting days, hours, and minutes since that event happened. When it happens again, you reset the counter — and every reset is saved with a timestamp and optional note. Over time, you build a complete history of when things happened and what you did.
What makes SinceNow stand out:
- Cross-platform sync — iOS, Android, and Web in one app. No other days since app offers all three.
- History with notes — Every reset is logged. Add a note like “Oil change at XYZ Garage, $85” and it’s saved forever.
- 33 ready-made templates — Car maintenance, health checkups, home tasks, habits — start tracking in seconds.
- Color-coded categories — Organize everything by domain: Home, Health, Car, Work.
- Reminders — Set recurring alerts so nothing falls through the cracks (Premium).
- Counter tasks — Count how many times something happened alongside tracking when (Premium).
Best for: Anyone who wants a complete tracking solution — home maintenance, health, habits, car care, and more.
Verdict: The most powerful and flexible days since app available. Free to start with no ads.
2. Days Since: Quit Habit — Best for Sobriety Tracking
Platforms: iOS only Price: Free with ads / Premium subscription
Days Since: Quit Habit has the most App Store reviews in the category (18,000+, rated 4.8★) and is deeply focused on one use case: tracking sobriety and quitting bad habits. It’s beautifully designed and has a strong community around it.
The downside? It’s iOS only, which means no Android or web access. And its focus on sobriety/habit quitting makes it a poor fit for general-purpose tracking like home maintenance or medical appointments.
Best for: iPhone users who specifically want to track sobriety or quitting a habit.
Verdict: Excellent for its niche, but too narrow for everyday life tracking.
3. DayCount — Simple iOS Counter
Platforms: iOS only Price: Free with ads / Premium
DayCount is a clean, minimal days since counter with 26,000+ App Store reviews (4.7★). It does one thing well: counts days since or until events. The interface is simple and the design is polished.
However, it lacks history with notes — you can see how many days, but not what happened each time. There’s no Android version, no web access, and no templates to get you started quickly.
Best for: iPhone users who need a simple counter with no frills.
Verdict: Good for basic counting, but lacks the depth that makes tracking actually useful.
4. dayssince.app — Minimal Web App
Platforms: iOS only (web app) Price: Free
dayssince.app is a bare-bones days since counter. It works as a web app on iOS and does the basics — tracking how many days since an event. The interface is extremely minimal, which some people appreciate.
It has no Android app, no history, no reminders, no categories, and no templates. It’s essentially a single-purpose timer with no depth.
Best for: iPhone users who want the absolute simplest possible counter.
Verdict: Too minimal for any serious tracking needs.
