What these grades rest on. Graded from this listing, whose facts were read from Simple Mobile Tool's own pages on 13 November 2026. Not based on using the product, and shorter than our full reviews. Its Google Play page did not show the price as plain text when we checked, so that figure is the listing's. How we review and grade.

Keep Simple Calendar Pro, or make your own?
Your call
A calendar at its plainest is events on a grid.
You could make the core of Simple Calendar Pro for yourself: calendar. What you would give up is listed below. Whether that is worth the price is your call. At $2.99, paid once, it costs less than the weekend it would take to replace, which is the argument for keeping it. Simple Calendar Pro is open source, so there is a third way: take its code and run it yourself.
What you could make
- Calendar: an app builder makes this well.
What you could not
- A real app for Android. Something home-made would be a web page.
- Hooks into the device itself: widgets.
What this rests on. Simple Calendar Pro’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
