for $4.49 a week the app is quite limited in its functions. The text is cut almost in half horizontally. App needs major improvements and upgrades or a much lower price.

Thanks for the feedback. The text issue on Fold devices is a bug — they’re only about 0.5% of our users, so this rare layout slipped through. We’re on it. If you’ve got specific gripes, email support@chippy.tools.

A quick look at app and is overall very good. Unlike most whingers here I am happy to pay for a good service however there is nowhere I have found that tells me price or term therfore a little shifty. Speaking runnong measurments a good option but could not see how to set how quickly they are spoken and no pause or replay last measurement option if you drop the tape or not hear a measurement, so have to start again from begining. Triangke solver is very confusing. Worth a look.

Hi Colin, Thanks for the review. The price of the app and term are clearly displayed within the app before purchase, which allows us to localise the price to each country. Controlling speaking speed is with our development team to improve. If you have any suggestions on how we could improve the triangle calculator, email support@chippy.tools

All this app does is Baluster spacing unless you buy the pro package. And any 5 year old can do that. Stop unless your like 4 and can't do Balusters then this app is useless unless you just want to kick out cash for apps you can get elsewhere free! When they replied that this app has usefulness without purchasing it, that must have been someone else's app they where referring to, it's certainly not that one. This is a waste of your data to download and your space to keep it. DELETE!
