Our philosophy

Our passion is to design user-friendly an unique apps for iOS-products. It starts with conception and design and ends with programming and marketing. Since we are continuously developing our products, we are grateful for any feedback we get from our users (support@onetwoapps.com

We look forward to receiving questions and suggestions sent to us via the app. We are grateful for every e-mail we receive. The advantage is that we can immediately see the device (iPad/iPhone/iTouch), the iOS firmware and the software version. We make an effort to respond to all e-mails in person as quickly as possible. 


If there are any problems, please don't just write a bad review full of questions. As we cannot read all reviews, we won't receive your questions this way. A further problem is that we cannot react to a bad review. Many misunderstandings can be avoided by clarifying things per e-mail.


Unfortunately, we currently do not support Android and Windows Phone. 


2016-10-01 : Our new iMessage stickers are online!

With the new operating system iOs 10, users are now for the first time able to garnish their iMessage-messages with animated pictures and stickers.



The installed iMessager-apps can be found next to the input field in the chat. Next to the buttons which have already existed before (arrow to the right), the App Store button will be visible. This is where the apps are hiding. In order to install them, you need to tap the four dots on the bottom on the left side first of all and then the desired app icon can be selected. To install further iMessager apps, tap the “+ Store” symbol and the iMessager-store will open. Select "categories"on top and search for "onetwoapps". After that, all available packets will be displayed. Here you can find out more about our stickers.

2016-09-28 : My Budget Book Pro Edition 1.0

You think this app is helpful? Then please write a review or recommend the app to a friend.

We developed the app „My Budget Book“ further and released a new free pro version „My Budget Book Pro Edition“. With this free version you can only create 16 entries per month and you cannot use any export functions (Excel, CSV, HTML, PDF). These limitations can be removed permanently via In App Purchase (2,99 USD).



It has a multitude of new functions. Additionally, the interface was restructured. Thereby, it can now be operated more intuitively and working with it is fun. New entries can be made quickly via self-defined hotkeys. For everyday expenditures you only need 3 clicks (e.g. purchasing a newspaper, buying a ticket, ordering a pizza, …). There is no quicker way to cover your expenditures. Convince yourself of the improved performance and just have a look at the app. Of course, both versions will be developed further. You can add the old backups to the pro version at any time. Further information here.

Enjoy the new version.

You can import the file if the format-settings are correct.

Support for the development

We would be pleased, if you support us (voluntary) with a fair and just assessment in the app store


A complex and expensive development only makes sense, if every user and not only the user with a negative attitude will evaluate the app. Unfortunately we receive some bad assessments, only because the icon may not be liked, or because of operating errors, or because of missing functions i never promised in this app. Even the smallest faults, misunderstood functions, or failures are evaluated with only one star ( which means a bad assessment).


After each release every user should or can leave a feedback in the app store, To support the further development we would be pleased for every fair assessment. Of course all errors will be fixed in the future and updates are provided free of charge. 

Thank you. 

Language Support

We would like to provide our app in additional languages. Should you have time and be interested, we would be happy if you translated our resource file (Excel) and the iTunes description (Word) into any language. Please write an e-mail to support@onetwoapps.com, so that we can discuss the process. Thank you!
