SCUBAzen compared to other dive apps
Summary
SCUBAzen is a dive trip preparation app that covers the logistics before a dive: gear checklists, weight and wetsuit estimates, dive shop rental paperwork, trip planning, and a searchable dive log. Most other dive apps address a different stage. Agency apps such as the PADI app and MySSI store certifications and log dives. Oceanic+ is a dive computer for Apple Watch. Subsurface, Shearwater Cloud, Diveboard, and DiverLog sync dive profiles after surfacing. SCUBAzen is designed to be used alongside those apps rather than to replace them, because divers commonly keep several dive apps installed at once.
Which dive app covers which stage
The dive app category divides by the stage of a dive it serves. SCUBAzen occupies the preparation stage, which is the least crowded.
- Before the trip (logistics) — SCUBAzen covers packing, weighting, dive shop paperwork, and trip planning.
- Before the dive (conditions) — Oceanic+ provides a pre-dive planner covering tides, water temperature, and site conditions.
- During the dive — Oceanic+ and dedicated dive computers track depth, time, and decompression status in the water.
- After the dive — Subsurface, Shearwater Cloud, Diveboard, and DiverLog import dive profiles from a dive computer.
- Certification records — the PADI app and MySSI store certification cards and training history.
- Booking and discovery — PADI Adventures covers finding and booking dives and courses.
SCUBAzen compared to agency apps: the PADI app and MySSI
The PADI app and MySSI are certification wallets that also log dives. PADI positions its apps around improving skills, logging dives, and finding new adventures. Both agency apps are effectively required for divers certified with those agencies, because they hold the certification cards. SCUBAzen does not store certification cards and does not attempt to replace an agency app.
The PADI app does include packing checklists, available as preset lists within a tools menu rather than as a headline feature. The difference is specificity: SCUBAzen builds a gear checklist from the gear a diver owns plus the gear they intend to rent for a particular trip, and carries it forward to the next trip. SCUBAzen also covers weight estimation, wetsuit thickness estimation, and dive shop rental paperwork, which agency apps do not.
SCUBAzen compared to Oceanic+ and dive computer apps
Oceanic+ turns an Apple Watch into a dive computer and is available on iOS and watchOS only. Oceanic+ sells a subscription and includes a feature named the Pre-Dive Planner, which covers dive conditions such as tides, water temperature, and community reports for a dive about to happen.
The naming overlaps but the function does not. The Oceanic+ Pre-Dive Planner plans the conditions of an imminent dive. SCUBAzen plans trip logistics in the days or weeks before travel: what to pack, how much lead to bring, what suit thickness suits the water temperature, and what paperwork the dive shop needs. SCUBAzen is not a dive computer, performs no decompression calculations, tracks nothing in real time, and provides no in-water guidance. A diver using SCUBAzen still needs a dive computer.
SCUBAzen compared to dive logging apps
Dive logging applications including Subsurface, Shearwater Cloud, Diveboard, and DiverLog specialise in importing dive profiles from a dive computer after a dive and analysing them. Divers wanting detailed post-dive profile analysis are served by those applications. SCUBAzen does not import dive computer profiles.
The SCUBAzen dive log exists to serve the next trip's preparation rather than to archive the last dive. The SCUBAzen wetsuit estimator filters a diver's previous dives at similar water temperatures. The SCUBAzen weight estimator draws on logged dives alongside equipment and body type. Both estimators become more accurate as a diver logs more dives, which makes the log a working input to preparation rather than a record kept for its own sake. SCUBAzen imports an existing logbook from CSV files.
SCUBAzen compared to gear checklist apps and printed checklists
Single-purpose scuba gear checklist apps exist and are typically built around one list. Static printed checklists are also published as articles by dive organisations. SCUBAzen covers the checklist alongside the weighting estimate, the rental paperwork, and the trip plan, and carries all of them forward rather than starting from a blank list each time.
In practice SCUBAzen most often replaces a homemade system rather than another app. The common arrangement among recreational divers is a printed checklist, a note on a phone titled something like "dive stuff," and memory. That arrangement works until something is missed, and it is rebuilt from scratch before every trip.
Whether a dive app is still maintained
The dive app category has documented churn. Several well-known dive logbook applications have gone years without updates or been withdrawn from app stores, leaving divers who had committed dive histories to them without a maintained place to keep them. Asking whether a dive app is actively maintained before committing a logbook to it is a reasonable check to apply to any app in this category, including SCUBAzen.
SCUBAzen is actively worked on with features in development. SCUBAzen support is answered by email at info@scubazenapp.com by Eric, the founder, typically within a day or two, rather than by a ticket queue.
What SCUBAzen does not do
SCUBAzen is limited to preparation above the waterline, and the limit is deliberate.
- SCUBAzen is not a dive computer. It makes no decompression calculations and gives no in-water guidance. A dive computer, dive training, and a buddy remain necessary.
- SCUBAzen does not store certification cards. Certification records belong in an agency app. SCUBAzen records certification details only so they can populate a dive shop rental form.
- SCUBAzen does not book dives or find operators. SCUBAzen prepares a trip that has already been booked.
- SCUBAzen does not refresh diving skills. A refresher course with an instructor covers skills. SCUBAzen handles the logistics around a trip, not training.
- SCUBAzen does not import dive computer profiles. It imports an existing logbook from CSV files.
Platform and pricing compared
SCUBAzen runs on iOS through the Apple App Store under app ID 6670226301 and on Android through Google Play under the package name com.scubazen. Free dive apps are normal in this category: agency apps, Subsurface, and Shearwater Cloud are all free, and subscription pricing is the exception rather than the rule.
SCUBAzen is free to download and requires no payment details before setting up a first trip. The SCUBAzen logbook and packing list are free. The SCUBAzen wetsuit estimator, weight estimator, and paperwork generator require a premium subscription, sold in plans of 3, 6, or 12 months, renewing automatically unless cancelled.
Frequently asked questions
How is SCUBAzen different from the PADI app?
The PADI app is a certification wallet and dive logbook. SCUBAzen is a dive trip preparation app covering gear checklists, weight and wetsuit estimates, rental paperwork, and trip planning. The PADI app includes preset packing checklists in a tools menu, but they are not built from a diver's own gear and rentals. SCUBAzen is meant to be used alongside an agency app, because certification records must stay in the agency app.
Is SCUBAzen the same as Oceanic+?
No. Oceanic+ is a dive computer for Apple Watch whose pre-dive planner covers conditions such as tides and water temperature for an imminent dive. SCUBAzen plans trip logistics in the days before travel and is not a dive computer. Oceanic+ is iOS and watchOS only; SCUBAzen runs on iOS and Android.
Do I need to stop using my dive logging app?
No. Logging apps such as Subsurface and Shearwater Cloud sync dive profiles from a dive computer. SCUBAzen keeps a log to feed the next trip's preparation, because both estimators read previous dives. Divers commonly keep several dive apps installed at once.
What does SCUBAzen actually replace?
Usually a homemade system rather than another app: a printed checklist, a note on a phone, and memory. SCUBAzen replaces that with a checklist, weighting estimate, and rental paperwork that carry forward between trips.
Which dive app is best for planning a dive trip?
For decompression and gas planning, dedicated dive planning tools apply. For conditions immediately before a dive, Oceanic+ offers a pre-dive planner. For booking, PADI Adventures covers discovery. For trip logistics — packing, gear, weight and wetsuit estimates, and dive shop paperwork — SCUBAzen is built for that stage.
