About this app

[nag is not a free product. After a free trial it needs a paid subscription. This keeps nag running bug-free for years, no ads, no data selling, just a reliable tool that works]

Hi there, we're Nadine & Robin, the two founders of nag reminder - the Essential, Persistent and Most Powerful Productivity App on Android 👋

🏁 The best way to know what nag is all about is to tell you directly why we developed the app and what problem we tried to solve. If you are interested in the features, just skip this section and scroll down.

PROBLEM:
We forgot things once in a while. Often small things like buying or taking care of something, paying a bill, redeeming a coupon etc. Sometimes also recurring things like disposing of compost, taking pills, doing laundry etc.

What to do then? Just download an app that reminds you, right? Well, we have tested all the Android to-do, productivity and reminder apps ourselves (we have about 100 productivity apps on our phones) and were not satisfied.

There were generally two problems:

1️⃣ Firstly, that these apps only remind you once and then give up. The apps are not intrusive enough. Sometimes a reminder just comes at an inappropriate time and you forget to do this reminder at all. The app should remind me then again until I have actually done it. One or two apps had this capability, but they failed in endurance testing over several weeks so you couldn't rely on the app. So it should be persistently nagging me.

2️⃣ Second, the apps are either way too complicated / have multiple use cases or are too simple and very limited in their power. We need an app that is focused on a few functions but does them better than anyone else.

SOLUTION
We have been working with several people since 2019 on a prototype that takes into account the above aspects and puts a productivity tool in your hands so you can be more productive than ever. With nag you will never forget anything!

--

To achieve the benefits described above, nag has the following features:

🔔 Persistent & Effective Reminders
Firing once is easy. Coming back is the hard part. Every repeat is re-checked against a reference implementation before we ship a release, so your monthly reminder lands on the right day. If it's in nag, you'll never forget it!

🔁 Most Powerful Reminders
From the simple daily & weekly reminders to the complex every-3rd-Monday-of-the-second-month kind of reminders.

⚡ Set & Postpone Reminders in Record Time
Workflow & time picker with 12 preset and fully customizable times.

🏝️ Works fully offline
With other apps, notifications start coming irregularly in offline mode, unlike with us. Even if you don't have internet for 3 weeks, reminders will come as scheduled.

A few words from our users:

"I really like that the app pings reminders several times so if I miss the first, it keeps going. Instead of silently sitting in the notification tray" by Snackrat

"I love it! its on my home screen next to my calendar (...) love that the reminders are simultaneously REALLY easy to make short ones, AND able to make detailed ones." by Snackrat

"I absolutely love this app!" by Beast1985

"Awesome! Saved me from multiple alarms! I absolutely LOVE this app. My daughter & I both have ADHD and have such a difficult time remembering small details so were constantly forgetting keys, lunch, homework, meeting notes etc" by Clair

If you have questions, do not hesitate to contact us. We are looking forward to your message :)

All the best from Switzerland

As someone who moved over from iOS, I've been looking for a replacement for the excellent Due app. Nag Reminder is the closest I've found to date. There are a couple of minor bugs that prevent me from rating this five stars. The first is that I can not dismiss the sample reminder meant to show how to postpone. The second is that when choosing a specific day of the month, it will read 31th instead of 31st as it should. It does the same thing with 3rd. It reads 3th. Other than that, it's good.

I love the app! It's straightforward and effective, and I was surprised to find nothing else comparable. I have a request: could there be a setting for the app reminders to function more like an alarm? For instance, it could buzz for a minute and auto-snooze for a minute until the task time is adjusted or completed. Alternatively, a simpler implementation could be to reduce the minimum auto-snooze time to smaller increments, such as 5 or 10 seconds as an option. Great work! 👍

hi :) thanks a lot for those kind words :)))! thats a good point, thanks! in general such options are kinda hard to implement because android is very restrictive with that kind of features (battery consuming). but I have just added that to our roadmap. have a gread day, robin

This app is a good start towards copying Due, an iOS app. Sadly, at the moment, it is buggy. The notification sound changes randomly. Also, the reminders don't fire when set, but a minute later. This is also random, as some go off when set, some don't. With both bugs I've tried clearing and resetting, but the issue persists. I contacted the Robin, whose reply was the standard (as evidenced here) "I've forwarded this to the developer..." For the price, NOT worth it.

Edit 04.04.2024: Wanted to followup. Bug should be fixed by now. Hey, app is now fully optimized for Android 14 (that was the reason for the bug). Cheers, Robin
