Tydlig

The best iOS, iPadOS calculator of all. Should be also for Mac OS. I think this is one of the best apps in iTunes Store.

And stopped working today just hangs on open

I hope this app always exists. It’s genuinely a must have for me now! So simple and elegant, but can be really useful and complex if you need it to be

An outstanding product It allows total flexibility when structuring calculations

Judge for yourself, once you try you may try others but you will always come back to this the best there is.

Thanks for such a beautiful and useful app, best calculator app I’ve ever used!

Easy to use and easy to record reason for a figure

Makes all the other calculators squirm with awkwardness at their clumsy buttons and lack of expression. You guys should make a spreadsheet now. Excellent for what-if measurements. e.g. Measuring bracket spacing for a curtain rod: length minus 10cm each end, divided by 3 for bracket spacing. But what if we take 5cm offset instead of 10, and have 4 brackets? 8 cm offset? Easy. Normal calculator, start over and refer back to your notes, and maybe key it in wrong because you’re tired from juggling these numbers in your memory. Tyldig, just click on the number you want to change and change it. It is a game changer for me. Thank you devs, good work.

Tydlig is an great calculator app that I use all the time, however it has one downfall. I've built up a suite of formulas that I use regularly to assist me with my day-to-day work (such as calculating breathing apparatus working durations for firefighters), without needing to remember complex formulas. However the more I use Tydlig (by adding more formulas) the more it becomes cumbersome to use, which is a real shame, as Tydlig doesn't allow more than one 'sheet' or screen. The result is that I need to cram all of my formulas onto one page, which makes it cumbersome to use frequently, and just as cumbersome (sometimes more so) to manage all of these formulas. The iPad app is a little better, though it also eventually falls victim to this issue too. Ironically more so owing to iPad's bigger screen size, which allows the user to add more, and more detailed, formulas. If we could save our formulas to 'sheets' in iCloud, this would allow users to manage all of their formulas so much better and allow formula sharing. I'm giving Tydlig 4/5 stars for this reason. Once Tydlig gains a 'sheet' feature that works with iCloud, I'd definitely give it 5/5 stars.

great for quickly rearranging numbers to see what works
