User reviews

Seems great! One suggestion

The app seems great and is exactly what I wanted, simple logging of habits without any expectation or streak to maintain.

One thing that I would love is the ability to view insights for whole categories. For example, I have a few physical hobbies (disc golf, rock climbing, and snowboarding) which are all categorized as such. I would love to be able to see an overview of how often I’m doing any of those things instead of being limited to viewing them individually.

I think this would make me pull the trigger on the pro version and would bring me to 5 stars.

9/10

Would be 10/10 if we could have an option to not include a time (like when a woman gets her period and it remains on a daily basis not hourly) and there’s a glitch on date calculation. Something I did the day before says “3 days”

Response from developer

Thank you for the review! All your suggestions and the mentioned glitch have been fixed. Now you can even track duration-based events like Period or Vacation/holiday, etc easily and get nice insights about the days spent on those activities. Hope you find them helpful.

Simple app, responsive developer

I’m so tired of apps that try to be all things to all people. This app just focuses on doing one thing well. Shortly after I started using it, I sent some feedback to the developer of things I thought would make it easier to use, and they put them in the next release about a week later! I hope they manage to avoid scope creep and just keep making it cleaner and better at what it does.

Predatory Subscription Pushing

When my subscription ran out, I no longer had access to all of my events. That’s fine, except MY ABILITY TO DELETE THEM WAS REMOVED. So they just sat there unchanging and locked until I deleted the app. This isn’t cool man. I might’ve resubscribed but definitely not after this

Response from developer

So sad to hear that. Looks like you haven't gone through the app settings. You will have access to all your data even after your subscription expires. Just that you cannot log events or modify the existing data. But you CAN EASILY DELETE ALL YOUR DATA by going to: Settings > Data & Backup > Erase All data. If you face any difficulties, please email support@devapt.com, and I'll be happy to help.

Very handy app

It’s very useful to be able to make a list of things I know I should do or want to do regularly and then have an easy dashboard where I can log when they actually happen. This helps put life into perspective and really helps to realign with what is most important in life. When I look at my log and see that I haven’t spent time with my little boy in a few days or even a week, that is an uncomfortable amount of time and reminds me that this is what I should be doing. Same goes for regular tasks that should be done on a schedule but sometimes aren’t such as computer backups, scanning accumulated receipts into PDF and filing them away, going outside to simply take a walk, etc. This is better than a recurring task list because the task list can be pushed aside while SinceWhen simply silently tracks how long its been since the last time this happened. No judgement, no nag. Just a simple reminder.
