Looking for ToDo app with (surprisingly) obscure feature

[yippy]

There is a feature that I want in a To-do app that I am finding surprisingly hard to find. I would like a form of repeating due-date that does x amount of time since the last time it was done. That last part I am finding exceedingly difficult to find. Almost all apps I have found so far essentially pre-schedule all of the repeating reminder and ignore when you last did it.

An example: Cleaning the house. I would like a reminder to do it every 2 weeks. However, sometimes, I might be gone or busy so I don't get to it until a week late. I want to then be reminded in 2 weeks, not 1 week because the task really doesn't help to do it sooner.

The only app I have found so far that does this is Remember the Milk but the $25/year price tag to actually make it useful (push notification! and syncing more than once a day) is quite pricey.

Does anyone know of any other apps that have this kind of reminder?

Hmmm... I haven't fully played around with all the features, but the app 2Do just miiiiight have what you're looking for. I was lucky enough to grab it when it was Apple's App of the Week and was free rather than the (I believe) $14.99 price tag. There is a "repeat upon completion" function for tasks that I believe would be able to be set how you're describing. I currently have some setup scheduled for certain days of the week (for instance, on Monday I have a list of Suppliers I need to review- next Monday's list only generates once I have completed today's review). But there are other options, such as "repeat on every given period" that may act such as you're describing.

I'm not certain on this tho and haven't tested it out to see if it works as you describe exactly. But I believe it may work that a repeat task will schedule the next event based on the ascribed period length and your completion of the prior event. I would look into it some more and please don't jump the gun on my mere suggestion if it is currently going for the full price - tho I would argue it is worth that price tag. But 2Do has a LOT of features packed into it, and I think there are online videos and what not delving into said features that may be able to answer whether it has what you're looking for.

Hope that helps, and best of luck finding what you're looking for!

Things by Cultured Code also does this. You set a repeating timescale such as "Repeat 2 week after the previous to-do has been completed".
