user expectation – How do I best make a tally of items on a mobile phone

I’m designing a wireframe for a mobile app for logging materials.
One of the features needs to be able to log the makeup of a material.

fx in the case of a technical fabric the composition can look something like:

30% WO, 30% CO, 20% AC, 10% PU, 10% WS

tallying to 100%

My main thinking sofar has been making an add button at the button at the bottom of the screen and then have the user add each individual part until the full composition is reached.

However where I’m unsure is how to make sure the full tally is 100% – not more not less, what sort of feedback?
But also how I would lay this out on the phone screen if I use a list and an add button?

Does anyone know of any apps that deals with something similar or know best practise for something like this?

Mobile data doesn’t work with Google Apps and Firefox browser, but works with Non Google apps like WhatsApp. Hotspot works fine too

After migrating to prepaid, not able to use mobile data on Google Apps like Play, Chrome etc. Firefox is also not working.

However can use other non Google apps like WhatsApp, Drawing apps etc. Also able to use Mobile data on PC via Mobile Hotspot.

No root, no changes. Mobile: Samsung J7 Max.

mobile – Combining 6 apps into one

I’ve actually been involved in something similar, and with more than six in one. In the end we went with the approach of having the main home screen of the app display an icon and label for each of the apps. This main screen also provided navigation to the overall help page and overall settings page. Below is a rough mockup of how it was designed:

enter image description here

I say “overall settings” because the settings icon at top right was for things like using iCloud, Backing up to Dropbox, Passcode Lock, Theme Colour, App Screen Layout, etc. In other words, settings that were for the entire app as a whole.

The “overall help” was just about the main app screen and what some of the overall settings meant.

Once the user tapped on each of the app options, the resulting screen also had an option for them to navigate back to the main “Apps” screen. And, depending on the app, they may have also had a dedicated ‘help’ or ‘settings’ screen.

Of course, in your case it may not need to be this advanced, but the point of sharing my example is because this works. User feedback has been extremely positive and this design is something that has evolved over time based on user feedback.

mobile application – Best practice for multiple select categories

Anything that is deeply nested or complex is always a challenge to display on mobile, so there is usually going to be a trade-off between what you can fit in the screen and what is easy to view at any given time.

If it is purely for the purpose of filtering, one strategy is to divide the single tree structure into separate filters, one of each category (assuming you won’t be adding to the top level categories) and then you’ll have a easier way to organise the items below and display their status (using counter to show how many selected in each category).

It is now standard or common practice to use tags that can be cleared or deleted when there is a complex selection process involved, so even though it looks crowded on the screen the fact is that it can be more practical when it comes to being able to easily see at-a-glance what all the filtering options are and removing them (but not to add).

android – Why is screen HEIGHT not taken into consideration while designing responsive layouts for mobile apps?


When we’re talking about the interfaces, we’re obliged to take into account the devices that makes us possible to display the content we aim to see. So that the main medium when the term responsivity was introduced was computer screens/displays and web through computers.

As you might imagine displays of all the computers/notebooks, the screens are rectangular on default and people using these displays intend to make browsers/applications minimized via reducing it’s width rather than the height as it opens more broader and wider area.


Doesn’t responsive layout mean that my app should look the same in devices of all widths and heights?

Well, it’s just because in these days mostly people are mobile users and the term need to be updated as the term responsivity originally also covers the same issue. Or there might be attempts to describe the concept differentially as only mobile users ran into this seperation since web is mostly on rectangular screens.

If 2 devices have a lot of difference in HEIGHT, my app in one device
will look drastically different from the one in other device

Besides you’re totally correct and even it’s the same for width for development point of view, it might mostly happening beacuse the heights are used %100 to fit all the screen sizes for mobile preferably. But that’s not my main arguement and point to avoid using responsivity as a height on mobile or web eventually.

navigation – How can I make an essential navigational treeview sidebar work on mobile?

I’m currently working on a web application that will have significant user-created content. I
would like to organize this content hierarchically, with a side-bar on the left to navigate, some buttons above it, a navbar at the top, and the main content to the right filling up the whole page. This is similar to what Atlassian’s Confluence does (except I’ll probably have a bit less text above the treeview for navigaton):

On a desktop or laptop, or even maybe a tablet, this works great — the user can quickly get an overview of the structure of the content that they’re looking at, collapse irrelevant parts, and quickly jump to any page. Additionally, I can use the space above the treeview to show other information and provide UI that is common to each section.

But, on mobile (a phone), this UI is much worse. I could have a collapsible sidebar to the side, but I’ve used a competitor web application that does this and it results in the system being very difficult to use. Furthermore, I already have a hamburger button for a collapsible navbar, so having two may be confusing, and at the very least will be clunky in any way that I can see to do it. I could put the sidebar before the main page content, but then the user has to scroll to get at the content on the page that they want to view, which is likely to be annoying, and I want a very smooth user experience. If I put it on the bottom, below the main content, then the user is liable to miss it.

As such, I ask, how can I take the information that is presented in this design on desktops and laptops, and cleanly, smoothly, reliably, and easily (for the user) present it on mobile?

EDIT: I tried loading a Confluence instance on my phone, and it was a disaster — it basically renders as a desktop application with some of the text enlarged. It looks like they put no thought into the mobile design, or, at least, if they did then it’s not setup on the instance that I checked.

bluetooth – Options for Integrating or developing a physical security solution (physical access control via in-house mobile apps [NFC/Bluetooh])

Our team is looking to either integrate or develop a physical security solution for a rather large campus.


Ability to either integrate (with reader/electronic lock hardware) from our mobile apps which would allow access control (over NFC/Bluetooth) to areas.

We will be writing to our already existing identity management api’s and expanding them to support what we need to for this project.

We are looking to write our own mobile integrations with purchased hardware, since this functionality has to exist within our organization’s already existing mobile apps we developed. (we haven’t found a company that offers the level of integration we want… most of the solutions we see out there are fantastic, but require downloading the security company’s mobile app, managing access control via their cloud resources, etc).

What reader/electronic door lock hardware can we buy to build this level of in-house integration with?

To summarize: we are looking to buy scanners/door locks with NFC/Bluetooth capability and write security integrations for access control through already existing mobile apps we have developed…

I realize product suggestions can be of bad taste on here, but I invite them for the sake of discussion in addition to solutions that companies offer.

Our team will be expanding to hire security professionals in this realm to assist, so you can save the “don’t roll your own auth” type of answers and comments 🙂

Thanks in advance!
