Live, AI Cloudspotter. NOTE: Newer devices are recommended for better performance in using this app. Recently got into the hobby of cloud-spotting? Ever wondered why different clouds have different looks? Atmosphere is the app for you. Leveraging on the latest machine learning and artificial intelligence technologies, Atmosphere classifies and tells you what kind of a cloud you are currently looking at, via your device’s cameras. Atmosphere includes the following features: ◆ LIVE CLASSIFICATION ◆ - Atmosphere processes each image frame from your camera using Artificial Intelligence, providing you with live classification results and confidence levels, of what it believes it is seeing. ◆ SNAP*, IMPORT* OR AUTO CLASSIFY ◆ - Take a picture of a cloud and that picture will be automatically classified according to the type of cloud it belongs to. - You can also import an image from your Photo Library for analysis by the AI. ◆ NO INTERNET CONNECTION NEEDED ◆ - This app processes everything on device, ensuring you all the privacy you deserve, while you spot the clouds. ◆ CLASSIFY IT THE WAY YOU LIKE IT ◆ - Artificial Intelligence can have its flaws at times, and when that happens, you can still take a picture of the cloud, and classify it yourself. ◆ NO TRACKING PRIVACY POLICY ◆ - Atmosphere does not, and will not track you. It’s that simple. Proudly Made in Singapore. Atmosphere is created by me, Vincent Neo, an individual developer. I believe that being curious about nature is amazing, and that this app would be able to tell individuals what cloud they are looking at, in an easy to use manner. Get Atmosphere Today! *In App Purchase is required for the picture taking feature. Prolonged use of app may decrease battery life more than usual, due to the heighten CPU usage when the camera is on, with live AI processing.

Practice holdings, radial intercepts, and DME arcs on your phone before your next simulator session. Calculate the procedure, fly it with live instruments, and review your track in the debrief. IFR Flight Simulator combines focused IFR procedure training with real-time flight simulation, worldwide navigation data, and a choice of glass cockpit or classic gauges. What you can practice: • Holding Trainer: Randomized holding situations. Determine the entry, calculate the wind correction angles, then fly the pattern. • Intercept Trainer: Inbound and outbound radial intercepts as well as QDM/QDR intercepts. • DME Arc Trainer: Fly DME arcs and calculate the angle of lead to turn onto the inbound course at the right moment. • Approaches: Set up a final intercept, a position in the pattern (downwind, base, or final), or a full approach at any airport, including ILS. • IFR mental math: Practice entries, wind correction angles, and lead points until the calculations become automatic. Worldwide navigation database: • Navigation data from a recent AIRAC cycle, with worldwide coverage: 13,000+ airports and 10,000+ VORs, NDBs, and other navaids. • Train with real airports and navaids instead of generic exercise locations. Real-time flight simulator: • Modern glass cockpit (PFD and ND) or classic gauges. • Autopilot with rotary controls for heading, altitude, and speed, or fly manually by tilting your device. • Fast-forward mode to repeat procedures efficiently. • Live Map: your position and flight path in real time. • Live Needle Overlay: watch where the HSI and CDI needles actually point as they move with the aircraft symbol across the map. • Optimal Holding Entry Path Overlay: compare your flown track with the wind-corrected entry and holding pattern. • Flight Log with Debrief: every flight is recorded. Replay the track and the needle movement, or resume the flight later. Built for instrument rating training, proficiency practice, and simulator assessments. "I am currently training for my Instrument Rating, and my FI recommended this app to me. I didn't think such a high quality, useful training tool was possible as an app. Incredible for VOR bearings, practicing holds and command headings." App Store review by Sa4mmy Questions or feedback?

Verdict

The call

The clearest difference is update cadence: IFR Flight Simulator at every 5 days against Atmosphere's every 3 months. IFR Flight Simulator also leads on rating (4.3 vs 4.1). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Atmosphere sells 1 one-off in-app purchase and IFR Flight Simulator sells 8 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

IFR Flight Simulator holds the better App Store score, 4.3 against 4.1. Both are backed by a comparable volume of ratings — 73 and 103 respectively. Written reviews complicate that: 67% of Atmosphere's written reviews are positive against 65% of IFR Flight Simulator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Atmosphere ships an update every 3 months, IFR Flight Simulator every 5 days. The most recent releases landed on October 7, 2026 and October 17, 2026 respectively.
