I recently unpublished Gallus — the first and only gyroscope stabilizing hyperlapse app on Android, capturing and stabilizing 4K/60FPS video in real time with overlaid instrumentation like route, speed, distance, etc — from the Google Play Store. It had somewhere in the range of 50,000 installs at the time of unpublishing, with an average rating just under 4.
It was an enjoyable project to work on primarily because it was extremely challenging (75% of the challenge being dealing with deficiencies of Android devices), and in the wake of the change a previous negotiation to sell the technology/source code and possible involvement was revived. That old discussion had been put on indefinite hold in an advanced stage when a buyer was acquired by a larger company, which quite reasonably led them to regroup to analyze how their technologies overlapped and what their ongoing strategy would be.
I put far too many eggs into that deal going smoothly, leading to significant personal costs. It taught me a lesson about contingencies. I’m pleased it is coming to fruition now.
I never had revenue plans with the free app by itself (no ads, no data collection, no coupling with anything else…just pure functionality), and ultimately the technology sell was my goal.
Nonetheless, the experience was illuminating, so I’m taking a moment to document my observations for future me to search up later-
- Organic search is useless as a means of getting installs. Use a PR-style approach. 50,000 is two magnitudes below my expectation.
- No matter how simple and intuitive your interface is, people will misunderstand it. When a product is widely used we naturally think “I must be doing something wrong” with the worst interfaces, putting in the time and effort to learn its idioms and standards. When a product isn’t widely used we instead think “This product is doing something wrong.” and blame the product. I abhor the blame the user type mentality, but at the same time it was eye opening how little time people would spend with the most rudimentary of investigations before giving up.
- The higher expectations are about your product — the more a user wants to leverage it and sees it adding value to their life — the more vigorous and motivated their anger/disappointment is if for some reason they can’t. Over the duration on the market some of the feedback I got because an app wouldn’t work on someone’s strange brand device that I’d never heard of, with a chipset that I’d never seen before, was extraordinary. A sort of “you owe me this working perfectly on my device“.
- The one-star-but-will-five-star-if-you… users are terrible people. There’s simply no other way to put it. Early on I played along, but quickly learned that they’ll be back with a one star in the future with a new demand.
- I have spoken about the exaggeration of Android fragmentation on here many times before: For most apps it is a complete non-issue. Most apps can reasonably target 4.4 and above with little market impact. Cutting out obsolete devices will often just save you from negative feedback later — it is Pyrrhic to reach back and support people’s abandoned, obsolete devices — but if you do try to reach back for 100% coverage it’s made easier with the compatibility support library.
At the same time, though, if you touch the camera pipeline it is nothing but a world of hurt. The number of defects, non-conformance, broken codecs, and fragile systems that I encountered on devices left me shell-shocked. Wrong pixel formats, codecs that die in certain combinations with other codecs, the complete and the utter mystery of what a given device can handle (resolution, bitrate, i-frame interval, frame rate, etc).For a free little app I certainly couldn’t have a suite of test devices (for a given Samsung Galaxy S device there are often dozens of variations, each with unique quirks), and could only base my work on the six or so devices I do have, so it ends up being a game of “if someone complains just block the device”, but then I’d notice months earlier that someone on a slight variation of the device gave a five star review and reported great results.
I enjoyed the project, and finally it looks like it will pay off financially, but the experience dramatically changed my future approach to Android development.
