I'm working on an app[0] that makes hosting temporary PDF forms simple, without needing an account or payment. You simply add input fields over any static PDF and publish it to get a link which you can send to other people who may need to fill the form.

The form stays online for 30 days. To keep the forms online for longer, I will be offering paid plans.

Well executed! Low fuss. The widget process was intuitive and worked good enough on mobile. Shareable link was easy.

Some minor thoughts: Are the radio buttons meant to have a big outline? Any way to erase the signature? What tech did you use for the frontend?

Thanks! The radio buttons as well as check boxes do show an outline so that they can be used in PDFs where no existing outline exists. If the PDF already has these outlines, the widgets can be resized so that the outlines of the widget match the existing ones.

You can erase existing signatures by overlaying a new signature widget on top of it and specifying a solid color as the background.

The frontend uses React, with Firebase handling most of the backend stuff.

I'm a father to two little boys and tracking their growth is typically done on paper charts such as https://www.cdc.gov/growthcharts/data/who/GrChrt_Boys_24LW_1... which are not very usable on screens and require you to draw lines with pen on the paper for accurate tracking. So I made a digital version instead with React and D3.

The charts are limited to those for children under two years of age since growth charts for older children differ based on nationality.

Thanks. Trees that are too big do get hard to manage currently and it is something I have been unable to decide on a solution for. I was thinking of allowing users themselves to expand or compress ancestors and descendants ( which would mean even more clicks :( ) to focus on the part of the tree they were currently working on.

No reason in particular, but I don't have a Facebook account so integration with Facebook would have required me to sign up first to test the integration. I don't mind creating an account on Facebook if required, but I am trying to avoid it if possible.

Oh, I just got downvoted, unsure why. I was thinking that it's a pretty neat tool to integrate with Facebook. As your primary goal is to build your family structure, you may want to share it with your family members (and maybe have them help building the tree).

Also, depending how you want to grow, fb login is typically the most successful one.

Thanks, that makes sense. I'll see how I can make it more intuitive

I recommend starting with one empty box (every family tree has at least one member) than an entirely blank screen.

Second that. The first time I opened the tab I thought it had failed to load and hit refresh. Only then I noticed the "plus" icon.

It's just svg circles animated with css so no libraries were required. I've tried to keep external libraries to a minimum

Thanks, I've tried to make onboarding easier by showing the popup tooltips, but I guess it needs more work

But aren't you still using the certificate to validate the receipt to find out which in-app purchases have been made?

If so, wouldn't you have to validate receipts against a new certificate once the old one expires?

Once the receipts for in-app purchases are validated, they don't need to be validated again every time. It's true that people wouldn't be able to make new in-app purchases (unless we have another payment processor as a backup). But at least their app will WORK! And we'll be able to communicate to them how to refresh the certificate and be able to make in-app purchases.

Do you have a link? I was just about to get started on a project and getting a $2 Arduino would be great for tinkering

Just a little bit more: http://www.aliexpress.com/item/Best-prices-UNO-R3-MEGA328P-f...

But if you are not planning on using shields you can get arduino mini for ~$1.3 or nano for ~$1.8

Go to AliExpress.com and search for "pro micro" or "pro mini".

You can get a Pro Mini clone for less than $1.50.

A full-size Arduino R3 clone (with a cheaper USB chip, the CH340G) is less than $3 with free shipping.
