14 Weird Android Apps I Don’t Want On My Phone

There are millions of titles available, and the usual tranche barely touches the surface in Google Play, at least… Outside of messaging, maps and browsers, there are a handful of visionary Android apps I will not hesitate to reinstall on any new phone because they’re so good at what they do that dropping them would seem tantamount to bailing on the future altogether; they wrestle with niche problems in exactly the right way; they teach me something exciting about our universe, or perhaps just make life more interesting one tap at a time.

Naming birds, plants, peaks and stars with smart apps

whoBIRD turns any hike into a field lesson. It leverages the BirdNET model trained by the Cornell Lab of Ornithology and German researchers to recognize species based on their sound using your phone mic. You can nudge accuracy by inputting season and region, which replicates the process by which ecologists restrict possible species in actual surveys.

PlantNet is where I turn to for my flora fix. Take a snap of the leaf or flower, choose your region and the app ranks likely species from a comprehensive image data store curated by European research centers like INRIA and CIRAD. It’s a part-identification tool, it’s a citizen-science project, and the results get better over time as community-validated submissions come in.

PeakFinder is hiking magic. Aim your camera at a skyline for an augmented sketch overlay with names and elevations of mountains. It operates offline, via GPS and preloaded panoramas, so you can trust it when your signal goes M.I.A. atop remote ridgelines.

Sky Map is an app that turns your phone into a mobile planetarium. Customized for your location and orientation, it identifies planets, constellations and bright stars. It’s particularly useful during astronomical events monitored by groups like NASA or when city light pollution turns naked-eye stargazing into Russian roulette.

Sound sleep and focus tools that truly stick around

Noice plays soothing soundscapes — campfires, coffee shops, light rain and good old brown noise — to lull you to sleep. Many people find white noise has a calming effect, the Sleep Foundation reports, as consistent background sound can help mask disruptive noises and allow some to fall asleep faster. Noice’s slick interface minimizes friction; the trade-off is you need a data connection if you’re going to stream.

Tomato is my minimalist Pomodoro. The technique, developed by Francesco Cirillo, divides work into intense sprints with brief recovery periods. Studies in the attention literature and beyond, such as at the University of Illinois, have shown that small breaks can help reboot attention and stave off mental fatigue. All in all, Tomato also sports a tasty Material design, not to mention that the persistence of its notifications makes it very easy not to lose track.

Designing your outdoor plans with accuracy and care

Golden Hour charts the movement of the sun and moon throughout the day, alerting photographers to golden and blue hour windows. Under the hood, it uses well-established solar position calculations that are already used by organizations like NOAA. Reminders, map overlays and moon phases help you time shoots instead of chasing them.

Book of Survival is the app I hope never to need, yet keep around anyway. It compiles offline primers on navigation, shelter, water, signaling and first aid. Preparedness advice from outfits like the Red Cross is all about planning in advance for calamities; this app puts crucial tips at your fingertips when connections to others — and nerves — are frazzled.

Everyday utilities with a twist that actually helps

Historical Calendar is an on-this-day engine for history buffs. It highlights significant births, achievements and turning points associated with any date, then adds quizzes and curated readings. It’s a light-touch way to turn idle minutes into a history rabbit hole.

Unit Lab is my trusty converter when recipes, road trips or repairs run into unfamiliar units. It supports volume, mass, temperature, pressure, energy, velocity and currency. The base conversions function offline — handy when kitchen counters are sticky and Wi‑Fi is shaky.

Entertainment Extras That Were Unexpected

RunPee is solving a weirdly ubiquitous problem: when to duck out for a bathroom break during a movie. It highlights safe, spoiler-free break times, reminds you not to leave your seat during the post-credits scenes — a superhero franchise tradition — and combines user ratings with fast links to major movie databases. It’s also surprisingly accurate, thanks to a combination of editor input and community contributions.

Drinkable is a free, open-source cocktail companion that filters recipes by what you have in your cabinet. It also serves as a party planner, complete with a shopping list and extensive recipe library. For home bartenders, it’s a smarter index card box that actually keeps up to date with your pantry.

Tracking the invisible infrastructure around us

MarineTraffic enables you to view the world’s shipping lanes in almost real time. It visualizes AIS broadcasts, which the International Maritime Organization requires of most large ships, to display origin and destination information, speed and class of vessel. Go down to any harbor and the silhouettes offshore are fairy tales made flesh.

WiFiAnalyzer is where I start when trying to fix my perpetually flaky home internet. It maps out nearby networks, the signal strength it can receive from each, and even noisy overlap conditions so that you can choose uncluttered channels — there’s often no clear path to settling on a Wi‑Fi channel in 2.4 GHz because only channels 1, 6 and 11 do not overlap, according to the IEEE 802.11 specification. A few minutes spent in the app will frequently result in a clear bump to your stability.

Why these apps feel different and keep earning a spot

They each solve a real, often strange problem with smart design: what you hear or see, falling asleep faster, triggering sunlight at the right times in your schedule, converting anything and avoiding buffering and bathroom breaks.

Amid a sea of sameness, they land on my phone and never leave because they are so deliciously specific — and endlessly useful.
