13 days ago34 proposalsRemoteCross-Platform Permission & Silencing Smartphone App
I am seeking an experienced app developer to create an application or both Android and iOS that manages device permissions and enables users to easily set their device to "Do Not Disturb" mode while silencing alarms. The app will require the following features: 1-Permission Management: Upon installation and first-time launch, the app will prompt users to grant necessary permissions to access system functions. Specifically, the app requires permissions to set the device to "Do Not Disturb" mode and silence alarms. This permission request dialogue will appear only once and will be repeated if the user denies permissions initially or decides to change the app's permissions later. 2- Cross-Platform Compatibility: It's crucial to understand that the permissions required differ between Android and iOS platforms. The app should handle these differences seamlessly and ensure proper functionality across both operating systems. 3- Efficient Functionality: The app should have just two buttons: one to enable the "Do Not Disturb" mode and silence alarms simultaneously, and another to revert all settings back to their original state. These buttons should provide users with quick and convenient control over their device's settings. 4- Reliability and Stability: The app must be stable and reliable, ensuring consistent performance across various device models and operating system versions. Ideal Candidate: - Prior experience in developing Android and iOS applications. - Proficient in permission management and location-based features.

IOS + Android development + upload to both stores.
I've been a designer for many years, and have even designed and helped develop an app a few years ago which lived on the IOS app store, so I'm fairly familiar with the process but don't really have the time, even with recent developments in AI! I have an app which i've recently designed and I need someone to develop and uploaded it onto both app stores. The app is fairly straightforward, and uses an API to call for information (I have the API key which I also need hidden - this is important). The information from the API will then provide the user with some information. The app mainly consists of 3 or 4 pages, and once the app saves a users location the user should only really need to stay on one page. I'm looking for some quotes at this stage. Please reply with your portfolio of work and your quote. I've set the budget at £300 but am open to offers. Regards Dean
