It is very handy to do conversions. ### 5/5 — Compass *2026-06-21, version 1.6.9* My absolute favorite. ### 4/5 — Petertelescope *2025-10-13, version 1.6.9* That’s great for setting up my 8” reflector telescope measuring latitude angle and hour angle and checking the reference aseisleve ### 3/5 — Possibly no longer supported *2025-09-13, version 1.6.9* This app still has some useful tools onboard although I certainly haven’t been using them all, so can only generalise, but I have noticed that the currency conversion tool no longer works (as of Sept’25) because when you tap the update button, (to the right of the word ”Currency” at the top of the screen) it comes back with, “Error updating exchange rates” and asks you to check your network connection. I would normally connect with the app developer but when you tap for App support, it takes you to an unused web address, plus the app was last updated (at time of reviewing) two years ago, so obviously no longer a priority for the developer. ### 5/5 — Real Treasure! *2025-07-26, version 1.6.9* I’ve had this app a long time and realized it was great but then I forgot it when I found apps that could do one of the options only. Only when I was desperate to find a good option for fractions did I came back to this. Now I will delete all the uni-taskers and keep this one. Oh, and it’s easy on the eyes. ### 5/5 — Brilliant! *2025-06-02, version 1.6.9* I had to upgrade my iPhone recently and needed a new DIY/carpentry app. This one has everything. The ruler is clever and the magnifying glass using the camera is amazing! Paid £1.50 - worth every penny. Thanks for all the development effort. ### 5/5 — Good app👍 *2025-04-04, version 1.6.9* I kinda wish I found out about this app before purchasing the pro feature on your ruler app but more than worth paying twice for so many features! ### 5/5 — Great *2025-03-03, version 1.6.9* Great collection But can u add a decimal point on calculator. I would use this over apple. ### 1/5 — Ripoff! *2025-02-01, version 1.6.9* Bought Metalbox years ago. Got a new phone and now 75% of the tools are locked saying I need to purchase metalbox again! TOTAL RIPOFF! ### 5/5 — Excellent App *2024-11-17, version 1.6.9* An multi-functional app that serves many purposes, that I would definitely recommend at any time without hesitation. Thank you so much developer for all the time and effort you put into this app and into also maintaining it on the AppStore. I hope more people support you via positive feedbacks and purchasing of your amazing app to make it worth your time and effort to keep it on the AppStore. Wishing you the very best for the future in every way Developer. Your efforts have been much appreciated & your app very well used by me!! ## Frequently asked questions about Toolbox™ ### What does this app do?
