PlanMyDay - Interview with the developer of a fantastic app

Did you have any prior development or coding experience?

Yes, I have been developing software since the early 80s. Starting with a Sinclair ZX80 with 1KB memory, I have been working in professional software development since the mid-80s. Since 2001, I also develop software for mobile devices. So there was an early version of PlanMyDay already for the PalmPilot, then for the Palm Pre-series, and finally, after their discontinuation, for Android devices.

What was the most challenging aspect of developing mobile app?

The biggest challenge is the incredible variety of devices that have to be taken into account during development. From mini-displays to tables, users want it to look and work well on all devices. Also, I'm always surprised how differently (and creatively!) users use the app. You can't foresee all that.

Name a few of your favorite apps and reason you love them.

- Automate: Because it allows me to perfectly automate processes on my
cell phone.
- Komoot: Because I can always plan and discover new hiking tours.
- Nova Launcher: Because you can really set and customize everything.
- TrackMyCoffe: Because it is also written by me :-)

How long have you been working on this app?

I have been working on the Android version since 2013. PlanMyDay is a purely private leisure project and many hundreds of hours of work have gone into its development.

What need of the user did you have in mind when developing this app?

The application was created out of personal need. I get distracted from my work reasonably quickly. Therefore, I needed a tool that on the one hand helps me to focus on a task, and on the other hand, I also wanted to know which tasks I can manage at all within one day. This only works with a time estimate and if you can assign priorities to the tasks. Besides, I have received quite a few letters from users who are struggling with ADHD and who seem to be really helped by PlanMyDay. Helping here fills me with great joy!

In what way do you think your app is better than similar apps on the market? Please describe in detail what innovation you think you bring and what you are proud of in your app.

What makes PlanMyDay so special compared to all other todo apps is the integrated time planning. Since each individual task can be assigned an estimated time, it is possible to calculate how long it will take until the tasks are completed. Time buffers can be automatically included, e.g. for breaks and disruptions. I am always surprised myself how well the time calculation fits.

It also motivates me a lot to get the task done before the scheduled time. If you have a feeling for the best priorities and for the duration of the individual tasks, the smart planning of the tasks, which tries to determine the best order, also works.

What are your future plans and expected features of the coming new versions of this app?

I am very cautious with new features. Why is that? Apple has had great success with the principle: Keep it small and simple. It is a great temptation to overload an app with newer and newer features. I try to avoid that at all costs. That's why I always think very carefully about which new features I include. In any case, it is very important to me to always adapt the app to the latest Android versions.

Assuming new users of your app are reading this page. What do you want to ask them to do (contact you about X, Share the app, etc.)?

Of course, I'm always most happy about recommendations when the app offers personal benefits. But also, success stories are a motivation for me to continue working on PlanMyDay in my spare time.


About App:

PlanMyDay – The relaxed feeling, to know always when the most important things will be done!

PlanMyDay allows real-time scheduling because it's more than just an activity manager. Your tasks get scheduled by their importance. Each task gets associated with a duration, a priority, and other attributes. Then all tasks can be ordered by their importance, simply by changing the order.

This allows at any time an overview, which tasks can be resolved in which time frame.
You can check in the current task, i.e. the elapsed time is counted in realtime. At the same time, the time scheduling for the following Tasks gets continuously updated. This makes PlanMyDay the perfect day-planning tool. Also, some users which suffer from ADHD use the app to avoid distractions.

Activities can be imported from Google tasks and/or from your Toodledo account or can be entered manually.
Also, events from your calendars can be imported, keep these time slots free for planning.

So you have a continuous overview, how much time is left for the day - the perfect day planning-tool.
