Neue App: Fuel Usage Tracker — Auch in Deutsch

Nachdem es bei der letzten App ja etwas Feedback gab, dass wir doch mal unsere Apps bitte auch in Deutsch online stellen sollen, jetzt hier heute also die Ankündigung: Unsere neue App “Fuel Usage Tracker” gibt es jetzt in Englisch und in Deutsch.

Fuel Usage Tracker hilft dir den Überblick über deinen Spritverbrauch zu behalten und ihn ggf. zu optimieren. Bei mir funktioniert das einwandfrei und es ist ein bisschen fast eine Challenge. Frei nach dem Motto: “Vielleicht schaffe ich bei der nächsten Tankfüllung doch noch einen halben Liter weniger im L/100km Verbrauch.”

Fuel Usage Tracker steht ab sofort zum kostenlosen Download bereit:

Wer die offizielle Ankündigung auf der Webseite lesen möchte, kann sich dies gern antun. Ist allerdings in Englisch: Fuel Usage Tracker Launched – Find out what your car’s real fuel consumption is

Aktuell werden Fahrzeuge mit Benzin und Diesel unterstützt. Bald sollen auch EVs folgen. Es können auch mehrere Fahrzeuge in einer App verwaltet werden, allerdings ist nur ein Fahrzeug kostenfrei. Sollte jemand mehr Fahrzeuge verwalten wollen, dann ist das Upgrade für €0,99 nötig. Des Weiteren erlaub Fuel Usage Tracker es, die Tankfüllinformationen als CSV Datei zu exportieren. Diese Dateien können dann ganz einfach in Microsoft Excel importiert und weiter verarbeitet werden.

Hier gibts noch ein paar Screenshots zum anschauen:

P.S.: Wer noch eine Kfz-Versicherung benötigt, kann sich gerne hier einmal umschauen: Günstige Kfz-Versicherungen.

New productivity app to reschedule tasks with fixed time spans

We recently launched this new app called ARS, which stands for Auto-Re-Schedule. It is a very niche productivity app for people who have tasks that need to be done at fixed time spans — starting from the time the task was completed.

Traditional productivity apps like Apple’s “Reminder” app, Google Calendar or the like, usually pre-schedule tasks for a certain date/time. For example, every Monday morning 8:00 am “Bring child to kindergarten”. Just an example, not that I would forget that 🙂 So technically, all future tasks of that one thing to do, are scheduled in advance for every Monday morning. There was simply no need for us to create another app that can do exactly the same.

Download & Full Announcement: ARS – Auto-Re-Schedule Launched – Reschedule Tasks with Fixed Time Spans

ARS is different. At ARS you can schedule a task for Monday 9:30am as “Pick up mail from postbox” and you can set a fixed time span, for example 7 days. So when you complete this task, it will automatically re-schedule itself 7 days after you have completed that task.

Early Completion. So if you pick up your mail early, say on Thursday morning 9:30am, you can mark your task as completed. It will automatically be re-scheduled for the next Thursday 9:30am, i.e. 7 days later.

Late Completion. Should you miss your time and complete the task two days late: Wednesday 9:30am; then you mark the task as “done” and it will automatically re-schedule itself for the following Wednesday at 9:30am, i.e. 7 days later.

Again, ARS works differently in that sense. Of course, you could keep using the existing Calendar/Reminder app and will work just as fine — as long as you manually edit the next alert time if you’ve completed your task early or late.

Use Cases. ARS only makes sense for very specific tasks, like emptying the postbox here in Germany. I have a maximum of 7 days I can keep my mail there before the post office ladies will send it back to the sender. So I’d like to make sure I pick up my mail on time. Same counts for pre-paid SIM cards in certain countries. In Hong Kong at Smartone for example, pre-paid SIM cards can be topped up and from the time of last top-up the card is valid for 180 days. If you top up early, that 180 day counter resets. So you got to make sure your SIM card is topped up on time and if you top up early, that fixed time span is being kept and the reminder to top up is being set properly.

ARS can be downloaded for free. Your first 3 reminders are free. If you’d like to use more, you can purchase the upgrade through the app for $0.99.

Yo compared to our Battery Watch app – Why Investors Value Yo At $10 Million – and – if Yo = $10m then Battery Watch = $20+m

I’m still baffled by the bold move of Silicon Valley investors valuing the company behind the Yo app at $10,000,000 USD. According to themselves Yo is:

The simplest & most efficient communication tool in the world.
Yo is a single-tap zero-character communication tool.
Yo is everything and anything, it all depends on you, the recipient and the time of the Yo.

To an ordinary mind like mine the app does not sound very interesting and from a targeting point of view too general than you could actually define a specific target audience for it. Yet, I was intrigued by the simplicity and most importantly by the buzz around it. About a month or so ago, I decided to download Yo. Right after it launched publicly, actually. I have 6 contacts on there and in the beginning it was kind of fun to Yo people just for the heck of it. Nowadays I only Yo ‘back’ if someone Yos me first.

The Wall Street Journal apparently has made a very compelling case that Yo might become a communications and marketing platform to allow people and brands to communicate with each other in a more simplified yet sophisticated way. For example, adding a link (that opens a website) to a Yo notification. To be honest, the real key word here is platform. That is what gets investors all nervous to throw money at you. To them, there is no benefit in funding just another app. It’s the platform behind the app that makes all the difference. Based on the anticipation of creating a simple and very direct marketing platform to bring brands closer to consumers makes check books open magically and throw money at an app that actually is absurd. In fact, Michael Santoli of Yahoo! Finance said: “When almost everyone immediately agrees that something is absurd – how can it possibly fail?”

So let’s look at the plain numbers thus far. According to the Yahoo! Finance article, Yo has “been downloaded 1 million times and has around 50,000 active users.” Based on a per active user valuation (which is how many tech and especially social media companies are valued by) that makes a staggering $200 per active user valuation. Compared to the $19bn WhatsApp takeover by Facebook which valued each of their 450 million active users at $42 per such user. The Yo valuation at 5 fold seems a little high. Anyway, another interesting aspect to look at, is the “stickiness” of an app. We at S4BB Limited look at a metric called “Retention” to determine the stickiness. In very simple terms, that’s the ratio between total downloads and active users. So at 50k active users and 1m total downloads, Yo has a retention of 5%. Common industry standard for a good / sticky app is something around the 20-25% retention mark.

Just to compare this to our recently re-launched Battery Watch app on Android: 193k total users, 103k active users, 58% retention. Here is a screen shot taken this morning in our Flurry app analytics console:

Based on the number of active users our valuation for Battery Watch should be twice the Yo valuation so we’d end up at $20 million. Based on the retention rate our Battery Watch should be valued at 11.6 times the Yo valuation. That would be an outrageous $116 million. Plus, compared to Yo, Battery Watch is even profitable already. Yo, b***!

Sure, Yo has all the publicity, the advantage of being located in Silicon Valley and the platform (hope) story behind it. While we don’t have the first and second point, our platform is currently being designed as well and will be launched in select markets very soon.

It remains to be seen how successful Yo can be in the long run. Right now it seems to be hip – at least on the investor and media side – but to build a long-term sustainable business model on top of that will be challenging. I wish the Yo team all the best in their endeavors.

More about Battery Watch: Battery Watch is a very simple, useful and yet fun battery monitoring tool. It combines essential battery information, useful TSA / UK DfT-compliant battery warnings with funny voices that make such a usually “boring / ordinary” utility app really fun to use.
