Historic app data from Project Management Software + Machine Learning = How much does it cost to build an app calculator

Replies
Ryan Hickman

I ran a few calculations to see how close the costs were to the prices my customers paid in the past for app development. It's pretty spot on. Once you think about all the changes the client will make, infrastructure and testing -- it's very justified.

Pros:

Easy to use and does a great job at asking the right questions.

Cons:

Sometimes the prices is a little high.

Totally agree. Clients always update their requirements once the features are developed which will cost more developing time and resources...
Ryan Hickman
I love the UX overall. Very simple and easy to use. Where did you get the data?
Wendy Dean
@ryanhickmam Thanks! The data comes from many agencies around the world. We actually export the data directly from project management tools of real projects.
Colin Winhall
I feel the training data in your model favours high-end development. The questions are also too broad to be accurate in estimations. I like the idea but I feel the result is untrustworthy.
Wendy Dean
@colinwinhall thanks for the feedback!! The data favors highly stable projects. When we gathered the data from project management tools our threshold for acceptance was based on projects that were flagged as completed. We found the average cost landing around $160-$180k. After adding in considerations for specialized features and infrastructure we seen that number climb. All things considered we may make a freelancer mode to represent the cost basis for lower-end dev. The challenge is finding the data. In our research it's close to 88% non-completion rate.

@colinwinhall I think the price is in a reasonable range for reference purpose....

I am amazed by seeing the cost few teams can charge for building a Tinder like app. ($3,25,000 if outsourced). My team can build this at 15% of the cost for both Android & iOS platform.
Wendy Dean
@vishalkrsingh it would be awesome if you could share some of your data. this is a machine-learned data set that calculates these prices. In fact you can read how we calculated everything here: https://medium.com/@team_96861/h...

I love the design. Concept is similar to Crew's How Much To Make An App but much nicer looking. Does the data come from your own organization?
Wendy Dean
@simgooder Thank you so much!!! The data comes from 41 dev shops across the world. We extracted data from the project management tools to calculate everything. The most important thing was that the apps were completed. That was something that was rare to see. Often the apps would be good and lower price, however they would not be complete so we did not factor their data in. We're always looking for data. So if you or any shop wants to share it would be great. It would improve the accuracy and become an even more useful resource for the community. Thanks again!

Your cost estimates are way way off. The cost estimate that you show is $145k for my app that I have fully outsourced and built for just $5k.

wrote a story recently on medium about pricing if it too cheap and too good to be true the project will never get completed Q - how many apps did you use to build your machine learning model ? just curious .

good luck - there a real need for such a product

Pros:

Smart - easy UI - reasonable prices - well put

Cons:

did it before me :-(

I liked the UX but I didn't like the fact I had to enter my email address - I didn't enter my email address
Wendy Dean
@dannyaziz97 @owenfar1 point taken. I think that by far this was the most discussed point from those who gave it a spin.

In my experience, most calculators and devshops will quote you WAY below the actual cost of the app, and the project will run over budget. I think that from a development point of view (feature-oriented) it becomes much clearer what the cost is going to be, and this calculator does a great job on focusing on those signals to quote you.

Only downside for me is, there's no timeline estimate -- so I guess that's more of a feature request! I'd love to see a breakdown of time estimates if this data is available as timeline is just as important as budget for me.

Pros:

Easy to use, nice UI, pretty cool idea, and finally some accurate estimates!

Cons:

Doesn't include timeline in report

Hi there! Cool idea =) Please make the 'Previous question' link readable on hover though πŸ˜‹ You also have a lot of typos ('featues', 'crpyto', ...) Bug: on Advanced features, you can select both 'None' and other features at the same time Bug #2: on Additional features, there's no 'None' button Last remark: quite unhappy that you request the email, even more so since you request it at the end, without being straightforward about it from the start. I'm not entering my email, since I don't see why you need it to show me the result. This feels fishy.
Wendy Dean
@c10v32c1u6 Thanks for the feedback! We're going to make those adjustments and post the change when we deploy them later today! On a sidenote: Do you freelance as a QA engineer! Could always use a hand πŸ˜‰
Wendy Dean
@c10v32c1u6 I had my engineer deploy those changes. Thanks again for the feedback πŸ™
Clo
@wendyde03942462 I can do basic testing but I'm not an engineer, so it really depends what you need =)
Wendy Dean
@c10v32c1u6 thank you, thank you. You are far too kind! Just trying to make the best product possible for the community.
Clo

The product doesn't seem to have been tested (eg: several typos, missing a 'none' button that should be available).

Moreover, it feels fishy that my email address is required at the end, in order for me to see the result. I'm not giving that info so easily, and I would have appreciated that it would have been clear from the start that my email address was needed.

Pros:

Cool idea, and the UI is not bad

Cons:

Not a good overall experience

I dont really understand how this website should help anyone in estimating the development costs of an app, you cannot do that by filling out a simple form.

Why would a User System cost 12k to develop? I can integrate a user system in an app for less than 12k lmao

Pros:

giving a few giggles

Cons:

the numbers are absolutely made up from nothing

Ahaha we used the same site template for our product today: https://www.producthunt.com/post... that’s really funny :)
Lorinda J Everette

Reaches the overall expectations of the application. Near time results, fast and easy to use.

Pros:

Concept, Interaction, Views

Cons:

Some of the applications in bottom are missing.

Lorinda J Everette
Cool application, useful data, lots of information, Fun going though different approaches. πŸŽ‰

I thought about this application so many times when i have to build an application of my own, but now I need not to worry, I can just use this application to understand the financial lines. Thank you for this application !

Pros:

UI, To the point, Fair numbers

Cons:

None

Jeremiah A Bray

Really neat idea and very well executed. The UI is really nice but a little sluggish sometimes.

The price quoted is high but reasonable--these are closer to the real cost, the cost after a project inevitably goes over budget. I will definitely be using this in my next project! Keep up the good work πŸ’ͺ🏻

Pros:

Excellent Idea

Cons:

Kinda slow some times

Tamisha C James

This application gives me a lot of options to choose from, based on my views on how to build my next application, Very useful to understand and plan an investment through this app. appreciate the work, well done !

Pros:

Many options to choose from, Very helpful

Cons:

Some times slow.

Tamisha C James
Neat design and usability, appreciate the way it shows the cost to make the application step by step.
